Product details
Overview
TPSMC7.5AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on power and signal lines. It features 7.5 V nominal breakdown voltage (VBR), 6.4 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 133 V maximum clamping voltage at 133 A peak pulse current, and operates up to +185 °C junction temperature.
For engineers reviewing the TPSMC7.5AHE3_A/H datasheet, TPSMC7.5AHE3_A/H pinout, TPSMC7.5AHE3_A/H application, or TPSMC7.5AHE3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, MSL Level 1 rating, 10 mA test current for VBR, and 500 µA max reverse leakage at VWM - critical for automotive and industrial overvoltage protection design validation.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with junction passivation optimized for high-reliability operation. Its 185 °C maximum junction temperature supports under-hood automotive environments and high-temperature industrial PCB layouts without derating penalties.
The device delivers 1500 W peak pulse power per 10/1000 µs waveform with low incremental surge resistance and fast response time, enabling effective suppression of ESD, lightning-induced surges, and inductive switching transients on DC power rails and sensor interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | Lower PPPM (600 W), smaller SMB package, 7.0 V VBR, 100 A IPPM | Insufficient for ISO 7637-2 Pulse 5a; limited to low-energy consumer interfaces | Select when board space is constrained and surge threat level is ≤ 600 W |
| TPSMC7.0AHE3_A/H | 7.0 V nominal VBR, 6.0 V VWM, identical package and AEC-Q101 qualification | Lower clamping threshold better suited for 5 V logic rails; same thermal and mounting behavior | Choose for tighter VWM margin in 5 V systems where 6.4 V headroom is excessive |
Compared with SMBJ7.0A and TPSMC7.0AHE3_A/H, the TPSMC7.5AHE3_A/H provides higher energy absorption (1500 W vs. 600 W or 1500 W), tighter VWM-to-VBR ratio for 12 V systems, and validated automotive reliability - making it optimal for demanding power rail protection where clamping voltage and surge endurance are co-critical.

FAQ
What is the breakdown voltage tolerance for TPSMC7.5AHE3_A/H?
The TPSMC7.5AHE3_A/H has a guaranteed breakdown voltage range of 7.13 V (min) to 7.88 V at 10 mA test current, with 7.50 V as the nominal value. This ±5% tolerance ensures consistent clamping onset across production lots and supports reliable overvoltage detection in safety-critical circuits. The parameter is measured per ANSI/IEEE C62.35 standards and verified during 100% production testing.
Is TPSMC7.5AHE3_A/H suitable for automotive applications?
Yes, TPSMC7.5AHE3_A/H is AEC-Q101 qualified and carries the HE3 suffix denoting RoHS-compliance and automotive-grade reliability. It supports junction temperatures up to +185 °C, passes MSL Level 1 reflow, and is rated for 1500 W transient suppression - meeting requirements for engine control, body electronics, and ADAS power rail protection per ISO 7637-2 and ISO 16750-2.
What is the maximum clamping voltage of TPSMC7.5AHE3_A/H at rated surge current?
The TPSMC7.5AHE3_A/H exhibits a maximum clamping voltage (VC) of 11.3 V when subjected to its rated 133 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This low clamping ratio (VC/VBR ≈ 1.51) ensures protected downstream components experience minimal overvoltage stress during surge events.
Does TPSMC7.5AHE3_A/H have polarity markings, and how is it oriented on PCB?
Yes, TPSMC7.5AHE3_A/H uses a cathode band marking on the SMC (DO-214AB) package to indicate the cathode terminal. During PCB layout, the banded end must connect to the higher-potential node (e.g., VIN, signal line), while the anode connects to reference ground - ensuring correct unidirectional clamping action during reverse-biased transients.
What is the reverse leakage current specification for TPSMC7.5AHE3_A/H at room temperature?
The TPSMC7.5AHE3_A/H specifies a maximum reverse leakage current (IR) of 500 µA at its 6.4 V stand-off voltage (VWM) and 25 °C ambient temperature. This low leakage preserves efficiency in always-on systems and avoids false triggering in high-impedance sensor bias networks, aligning with design needs for battery-powered and precision analog applications.
