Applications
The TPSMC24CA is used for ESD and surge protection on 24 V automotive supply rails, industrial sensor interfaces, and RS-485 or CAN bus transceiver inputs where bidirectional transient suppression is required. Its 1500 W peak power rating and AEC-Q101 qualification make it suitable for powertrain ECU input protection, ADAS sensor supply clamping, and motor drive gate drive protection circuits. The DO-214AB SMC surface-mount package facilitates automated PCB assembly in high-reliability production environments.

Frequently Asked Questions
What is the peak pulse power and clamping voltage of the TPSMC24CA, and how do these values protect a 24 V supply rail?
The TPSMC24CA is rated for 1500 W peak pulse power using a 10/1000 µs test waveform, with a maximum clamping voltage of 33.2 V at peak pulse current. On a 24 V supply rail, any transient above 22.8 V (minimum breakdown) triggers conduction, and the diode clamps the line to 33.2 V or below, protecting downstream components from damage during lightning-induced surges or load-dump events up to 1500 W.
Why is the bi-directional CA suffix important for protecting CAN bus or RS-485 interfaces compared to a uni-directional variant?
The CA suffix in TPSMC24CA indicates bidirectional clamping, allowing the device to suppress both positive and negative transient spikes. RS-485 and CAN bus lines swing across a differential voltage that can go both positive and negative relative to ground; a uni-directional TVS would only clamp one polarity and leave the other unprotected. The TPSMC24CA clamps transients in both directions within a ±33.2 V window, providing full-cycle protection for differential communication interfaces.
What automotive qualification does the TPSMC24CA hold, and which vehicle system designs can it support?
The TPSMC24CA is qualified to AEC-Q101, the automotive component stress test standard, confirming reliable performance from -55°C to +150°C under automotive thermal and mechanical stress. This qualification makes it suitable for 24 V vehicle supply protection in heavy-duty truck ECUs, ADAS sensor power supply inputs, body control modules, and EV battery management systems where IEC 61000-4-5 surge immunity up to 1500 W is required.
How does the DO-214AB SMC package of the TPSMC24CA influence PCB thermal dissipation compared to smaller SMD packages?
The DO-214AB SMC package of the TPSMC24CA has a thermal resistance of approximately 40°C/W junction-to-lead and benefits from a large solder pad footprint of about 7.5×5.6 mm, which improves heat spreading into the PCB copper pour compared to smaller DO-214AA (SMA) or DO-214AC (SMB) packages. Designers targeting 1500 W peak pulse handling should use a minimum 1 oz copper pour area of at least 1 cm² under the SMC pad to maintain junction temperature below 150°C during repetitive surge events.
