The SMAJ51CA-E3/61 is a bidirectional transient voltage suppression (TVS) diode from Vishay Dale. It is designed to protect voltage-sensitive electronic components from transient overvoltage events. This device features a working standoff voltage of 51V and a maximum clamping voltage of 82.4V.
Key electrical ratings include a peak pulse power dissipation of 400W for a 10/1000μs waveform, with a reduced rating of 300W above 78V. The junction operating temperature range spans -55°C to 150°C, and the device can dissipate up to 3.3W when mounted on an infinite heatsink at 50°C ambient.
Packaged in a DO-214AC (SMA) surface-mount package, this TVS diode is suitable for automated assembly. It is commonly used in power supplies, industrial controls, and automotive electronic modules for circuit protection against surges and transients.
