If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected. **1.** VDRM and VRRM for all types can be applied on a continuous basis. Ratings apply for zero or negative gate voltage; however, positive gate voltage shall not be applied concurrent with negative potential on the anode. Blocking voltages shall not be tested with a constant current source such that the voltage ratings of the devices are exceeded. **2.** Torque rating applies with use of compression washer (B52200-F006 or equivalent). Mounting torque in excess of 6 in. lb. does not appreciably lower case-to-sink thermal resistance. Anode lead and heatsink contact pad are common. (See AN209B). For soldering purposes (either terminal connection or device mounting), soldering temperatures shall not exceed +200°C. For optimum results, an activated flux (oxide removing) is recommended. **==> picture [506 x 318] intentionally omitted <==** **----- Start of picture text -----**<br> Thermal Characteristics<br>Rating Symbol Value Unit<br>Thermal Resistance, Junction−to−Case (AC) R Ɵ JC 3.0 °C/W<br>Junction−to−Ambient R Ɵ JA 75<br>Maximum Lead Temperature for Soldering Purposes, 1/8” from case for 10 seconds TL 260 °C<br>Electrical Characteristics - OFF (TJ = 25°C unless otherwise noted)<br>Characteristic Symbol Min Typ Max Unit<br>Peak Repetitive Forward or Reverse Blocking Current(VAK = Rated VDRM and VRRM; RGK=1Kohm) TTJJ = 25°C = 110°C IIDRMRRM, -- -- 20010 µA<br>Electrical Characteristics - ON (TJ = 25°C unless otherwise noted)<br>Characteristic Symbol Min Typ Max Unit<br>Peak Forward On−State Voltage (Note 3) (ITM = 4 A Peak) VTM _ _ 2.0 V<br>Gate Trigger Current (Continuous DC) (Note 4) (VRAKL = 100 Ω) = 7 Vdc; IGT _ _ 200 µA<br>(TC = −40ºC) _ _ 500<br>Gate Trigger Voltage (Continuous DC) (Note 4) (VAK = 12 V; RL = 100 Ω, TJ=110°C) VGT _ _ 1.0 V<br>Gate Trigger Non-Trigger Voltage (Note 4) VAK = 12VDC; RL = 100 Ω) VGD 0.2 _ _ V<br>Holding Current (VAK=7V,, Initiating Current = 200 mA, RGK = 1kΩ) IH _ _ 5.0 mA<br>**----- End of picture text -----**<br> © 2020 Littelfuse, Inc.

Founded in 1927 and headquartered in Chicago, Illinois, Littelfuse is a premier global manufacturer of circuit protection, power control, and sensing technologies. Widely recognized for pioneering the first small, fast-acting protective fuse, the company has grown into an industry leader whose highly reliable components are essential to modern industrial, transportation, and consumer electronics applications worldwide. At the core of the Littelfuse portfolio is an expansive and industry-leading range of circuit protection solutions. This encompasses a massive selection of traditional fuses, fuse holders, and resettable PTC thermistor fuses designed to safely interrupt overcurrent conditions. To defend against electrical overstress, Littelfuse also provides advanced transient voltage suppression (TVS) technologies, including thousands of specialized TVS diodes, TVS varistors, and gas discharge tubes (GDTs) that ensure robust defense against voltage spikes and environmental hazards. Beyond its foundational protection components, Littelfuse manufactures a diverse array of discrete semiconductors, sensors, and switching devices. Engineers rely on their high-performance thyristors, including TRIACs and SCRs, alongside power-efficient Schottky diodes and MOSFETs for demanding power control applications. Complemented by precision proximity sensors and highly reliable reed and solid-state relays, Littelfuse delivers the critical building blocks required for secure, efficient, and complete system design.
