Product details

1500W peak pulse power, 5V rail protection – DO-214AB SMD

The SMCJ5.0CE3/TR13 is a bidirectional Zener TVS diode from Microchip, rated for 1500W peak pulse power per the 10/1000 µs waveform. It clamps a 5V nominal rail at 9.6V maximum, with a breakdown voltage starting at 6.4V. This part is typically specified for general-purpose transient suppression on low-voltage DC buses, signal lines, or I/O ports where a single bidirectional device protects against both positive and negative surges.

Clamping voltage, peak current, and temperature range

At the 1500W peak pulse rating, the device handles 156.2A of peak pulse current (Ipp) under the 10/1000 µs test condition. The 9.6V clamping voltage means a 5V supply rail sees less than 10V during a surge event — well within the tolerance of most 5V logic and transceivers.

Active lifecycle and surface-mount packaging

The DO-214AB (SMC) package is a standard JEDEC outline with a low profile for dense PCB layouts.

Frequently asked questions

Is the SMCJ5.0CE3/TR13 bidirectional or unidirectional?

It is a single bidirectional channel, meaning it clamps both positive and negative transients with one device. This simplifies BOM placement on AC-coupled or bipolar signal lines where two unidirectional diodes in anti-series would otherwise be needed.

Can SMCJ5.0CE3/TR13 be used in automotive applications?

The evidence does not list an AEC-Q101 qualification, so it is not formally automotive-grade. However, its -65°C to 150°C operating range covers typical underhood temperatures. For production automotive designs, verify with Microchip whether a qualified variant exists in the SMCJ family.
