Product details
Overview
TPSMC7.5HE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, designed for clamping inductive switching surges and lightning-induced transients on power rails and signal lines. It features 6.75 V to 8.25 V breakdown voltage (VBR), 6.05 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 μs), 128 A peak pulse current (IPPM), and 11.7 V clamping voltage (VC) at rated surge - used in automotive power supply protection and industrial sensor interface circuits.
For engineers reviewing the TPSMC7.5HE3_A/I datasheet, TPSMC7.5HE3_A/I pinout, TPSMC7.5HE3_A/I application, or TPSMC7.5HE3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 185 °C junction temperature rating, DO-214AB mechanical compatibility, and clamping performance under 10/1000 μs surge conditions.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with optimized junction passivation for stable high-temperature operation up to TJ = 185 °C. Its unidirectional architecture provides low forward voltage (VF = 3.5 V at 100 A) and fast response time to transient events.
The device meets MSL Level 1 per J-STD-020 with 260 °C reflow peak, uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and passes JESD 201 Class 2 whisker testing - confirming suitability for automotive and industrial reflow assembly.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.5AHE3_A/I | Lower PPPM (600 W), same DO-214AA package, tighter VBR tolerance (±5 % vs. ±10 % for TPSMC7.5) | Targeted for lower-energy transients; not rated for AEC-Q101 | Select when cost sensitivity outweighs automotive qualification and 1500 W surge requirement |
| TPSMC7.5AHE3_A/I | Higher VBR (7.13–7.88 V), same package and rating, ±5 % tolerance (denoted by "A" suffix) | Better noise immunity in noisy 5 V systems due to higher VWM (6.4 V) | Choose for designs requiring tighter voltage margin between VWM and nominal rail voltage |
Compared with SMBJ7.5AHE3_A/I and TPSMC7.5AHE3_A/I, the TPSMC7.5HE3_A/I delivers higher surge energy handling and automotive qualification at the expense of looser VBR tolerance - making it optimal for cost-constrained, high-reliability 12 V automotive subsystems where 1500 W clamping is mandatory.

FAQ
What is the breakdown voltage range for TPSMC7.5HE3_A/I?
The TPSMC7.5HE3_A/I has a specified breakdown voltage (VBR) range of 6.75 V minimum to 8.25 V maximum at 10 mA test current. This ±10 % tolerance reflects the standard binning for the non-"A" variant and ensures reliable initiation of clamping above the 6.05 V stand-off voltage (VWM) under defined test conditions.
Is TPSMC7.5HE3_A/I qualified for automotive applications?
Yes, the TPSMC7.5HE3_A/I is AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 22-Jul-16 (Document Number: 88407). This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and mechanical shock - validating its use in automotive powertrain, body electronics, and ADAS systems.
What package does TPSMC7.5HE3_A/I use and what are its mounting requirements?
The TPSMC7.5HE3_A/I uses the DO-214AB (SMC) surface-mount package. Per Vishay specification, it must be mounted on 8.0 mm × 8.0 mm copper pads at each terminal to achieve rated 1500 W peak pulse power. The cathode is marked by a color band, and the device meets MSL Level 1 with 260 °C reflow peak.
How does TPSMC7.5HE3_A/I differ from TPSMC7.5AHE3_A/I?
The TPSMC7.5HE3_A/I has a VBR range of 6.75–8.25 V (±10 %), while TPSMC7.5AHE3_A/I offers tighter 7.13–7.88 V (±5 %) tolerance. Both share identical package, power rating, and AEC-Q101 qualification, but the "A" variant provides higher VWM (6.4 V vs. 6.05 V), improving noise margin in sensitive 5 V applications.
What is the clamping voltage of TPSMC7.5HE3_A/I at its rated surge current?
The TPSMC7.5HE3_A/I exhibits a maximum clamping voltage (VC) of 11.7 V at 128 A peak pulse current under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during a full-rated transient event.
