## Description

The SMBJ43A is a unidirectional transient voltage suppressor (TVS) diode engineered by Taiwan Semiconductor, housed in a low-profile surface-mount DO-214AA (SMB) package with 2 pins. Designed for robust circuit protection, this device features a glass-passivated junction capable of delivering a peak pulse power dissipation of 600W using a standard 10/1000µs waveform. It provides a reverse standoff voltage ($V_{WM}$) of 43V, with a minimum breakdown voltage ($V_{BR}$) of 47.8V and a maximum breakdown voltage of 52.8V tested at a 1mA test current ($I_T$). 

Optimized for high-reliability applications, the SMBJ43A offers a maximum clamping voltage ($V_C$) of 69.4V at a peak impulse current ($I_{PP}$) of 9.0A, alongside a low maximum blocking leakage current ($I_{IR}$) of 1µA at the working standoff voltage. The component supports a wide operating and storage temperature range of -55°C to +150°C, exhibiting a junction-to-case thermal resistance ($R_{\theta JC}$) of 10°C/W and a junction-to-ambient thermal resistance ($R_{\theta JA}$) of 55°C/W. Its fast response time—typically less than 1.0ps—ensures immediate clamping of fast-rising voltage transients.

The DO-214AA (SMB) package is engineered for automated pick-and-place assembly, featuring matte tin-plated leads that comply with J-STD-002 solderability standards and meet JESD 201 Class 2 whisker test requirements. The molding compound achieves a UL 94V-0 flammability rating. This TVS diode is widely deployed in switching-mode power supplies (SMPS), telecommunication infrastructure, and industrial electronics to safeguard sensitive downstream silicon against electrostatic discharge (ESD) and inductive switching surges.

**Notes:** 

1. VBR measure after IT applied for 300μs, IT=square wave pulse or equivalent. 

2. Surge current waveform per Figure. 3 and derate per Figure. 2. 

3. All terms and symbols are consistent with ANSI/IEEE C62.35. 

4. For bidirectional use C or CA suffix for types SMBJ5.0 - SMBJ170 

5. For bipolar types having VWM of 10 volts (SMBJ8.0C) and under, the ID limit is doubled.
