Product details

TVS Diode for 70V Rails – 1500W Peak Pulse, Bidirectional

The SMCJ70CE3/TR13 is a bidirectional Zener TVS diode from Microchip Technology, rated for 1500W peak pulse power (10/1000µs waveform) with a reverse standoff voltage of 70V. It clamps transients to 125V maximum at 12A peak pulse current, making it a fit for protecting 48V to 70V DC power buses, telecom lines, and industrial control inputs against surges. The DO-214AB (SMC) package is surface-mount, with a wide operating temperature range from -65°C to 150°C junction, suited for outdoor or under-hood environments where thermal cycling is a factor.

The 12A peak pulse current (Ipp) at the clamping voltage gives the actual current the diode will shunt during a surge. If your application has a known source impedance, you can calculate whether the diode will stay within its SOA — for example, a 1000V transient through a 50-ohm source yields 20A, which exceeds this rating, so a higher-power TVS or series resistance would be needed.

Frequently asked questions

What is the difference between SMCJ70CE3/TR13 and SMCJ70A?

The SMCJ70CE3/TR13 is a bidirectional TVS (single bidirectional channel), while the SMCJ70A is unidirectional. Both share the same 70V reverse standoff voltage, 1500W peak pulse power, and DO-214AB package. Choose the bidirectional version when the signal or power rail swings both positive and negative relative to ground, such as on AC-coupled lines or bipolar supplies.

Is SMCJ70CE3/TR13 RoHS compliant?

The evidence does not explicitly list RoHS compliance status, but Microchip's standard TVS diodes in this series are typically RoHS-compliant and lead-free. Confirm the specific date code and lot against the manufacturer's RoHS certificate at order time.
