## Description

The 1N3070TR from Onsemi is a small signal silicon junction diode housed in a through-hole DO-35 (DO-204AH) axial package with two pins. Engineered for high-voltage general-purpose rectification and fast-switching circuits, this 2-pin single-configuration device handles a repetitive peak reverse voltage of 200V and an average rectified forward current of 500mA at a maximum operating junction temperature of 175°C. It features a maximum forward voltage drop of 1V at a test current of 100mA, a non-repetitive peak forward surge current capability of up to 4A (1-microsecond pulse width), and a tightly controlled reverse recovery time (trr) of 50ns using 30mA forward and reverse test currents.

Thermal and electrical characteristics include a power dissipation rating of 500mW with a junction-to-ambient thermal resistance of 300°C/W, alongside a low total capacitance of 5pF at 0V and 1MHz. Reverse leakage current is maintained at a maximum of 100nA at 25°C under a 175V reverse bias, increasing to 100µA at an elevated operating temperature of 150°C. The component's robust voltage handling and quick recovery profile make it well-suited for high-frequency signal demodulation, clamping, logic switching, and medium-voltage freewheeling or decoupling applications within industrial and consumer electronic systems.

- These ratings are limiting values above which the serviceability of the diode may be impaired. 

## **NOTES:** 

- 1) These ratings are based on a maximum junction temperature of 200 degrees C. 

- 2) These are steady limits. The factory should be consulted on applications involving pulsed or low duty cycle operations.
