Product details
Overview
TPSMC7.5AHE3/57T 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 a 7.5 V nominal breakdown voltage (VBR), 6.4 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 11.3 V maximum clamping voltage at 133 A, and 185 °C maximum junction temperature - enabling robust protection in automotive and industrial power rails.
For engineers reviewing the TPSMC7.5AHE3/57T datasheet, TPSMC7.5AHE3/57T pinout, TPSMC7.5AHE3/57T application, or TPSMC7.5AHE3/57T equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, 133 A peak pulse current rating, low clamping ratio (VC/VBR ≈ 1.51), and compatibility with high-temperature PCB assembly up to 260 °C reflow.
Technical Context
This TVS diode operates as a voltage-clamping device triggered by overvoltage events exceeding its 7.5 V breakdown threshold. Its passivated anisotropic rectifier structure ensures stable avalanche behavior under repetitive surge conditions, with thermal derating defined per Figure 2 for operation above 25 °C ambient.
The device delivers 1500 W peak pulse power handling using the standardized 10/1000 µs waveform and exhibits low incremental surge resistance, resulting in tight clamping performance (11.3 V at 133 A). It is rated for 200 A non-repetitive forward surge current (8.3 ms half-sine) and maintains functionality across -65 °C to +185 °C junction temperature range.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.5A | Lower peak pulse power (600 W), same VBR and package (SMB/DO-214AA) | Not suitable for 1500 W surge requirements; limited to lower-energy transients | Select only when system-level surge testing confirms <600 W compliance and space constraints favor smaller SMB footprint |
| TPSMC7.5AHM3/57T | Halogen-free variant; identical electrical specs and AEC-Q101 qualification | No functional difference; required only where halogen-free material compliance is mandated | Choose HM3 when RoHS + halogen-free certification (e.g., IEC 61249-2-21) is contractually required |
Compared with SMBJ7.5A and TPSMC7.5AHM3/57T, the TPSMC7.5AHE3/57T offers higher surge robustness (1500 W vs. 600 W) and full automotive qualification out-of-box, while maintaining identical mounting and circuit integration - making it the preferred choice for demanding automotive and industrial power-line protection.

What is the maximum clamping voltage of TPSMC7.5AHE3/57T and at what current is it specified?
The TPSMC7.5AHE3/57T has a maximum clamping voltage (VC) of 11.3 V, measured at its peak pulse current (IPPM) of 133 A using the 10/1000 µs waveform. This value reflects worst-case clamping performance under standardized surge conditions and is used to verify safe voltage margins for downstream components.
Does TPSMC7.5AHE3/57T support lead-free reflow soldering?
Yes, TPSMC7.5AHE3/57T meets J-STD-020 MSL Level 1 and supports peak reflow temperatures up to 260 °C, fully compatible with standard lead-free SAC305 solder profiles. Its matte tin-plated leads are solderable per J-STD-002 and JESD22-B102, and it passes JESD201 Class 2 whisker testing.
How does the leakage current of TPSMC7.5AHE3/57T compare at elevated temperature?
At VWM = 6.4 V, TPSMC7.5AHE3/57T exhibits 500 µA maximum reverse leakage at 25 °C and 5000 µA (5 mA) at 150 °C junction temperature. This controlled increase ensures stable standby behavior in high-temp environments while maintaining effective clamping integrity during surge events.
