Product details
Overview
TPSMC7.5AHM3_B/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping inductive switching transients and lightning-induced surges 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 - deployed in automotive power supply rails and industrial sensor interfaces.
For engineers reviewing the TPSMC7.5AHM3_B/H datasheet, TPSMC7.5AHM3_B/H pinout, TPSMC7.5AHM3_B/H application, or TPSMC7.5AHM3_B/H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating curves, SMC package mechanical data, and direct alternative part comparisons for surge protection design validation.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with optimized junction passivation for stable clamping under high-temperature operation. Its unidirectional polarity enables forward-biased surge conduction during overvoltage events on DC-biased lines, while maintaining low leakage (<500 µA at VWM) at 25 °C and <5000 µA at 150 °C.
The device delivers 133 V clamping voltage at 133 A IPPM (10/1000 µs waveform), with 0.052 %/°C temperature coefficient of VBR, enabling predictable voltage margining across -65 °C to +185 °C operating range. It meets MSL Level 1 per J-STD-020 and is halogen-free, RoHS-compliant, and AEC-Q101 qualified.
Key Specifications

Use Scenario: Adding secondary-level surge protection on VBUS line of USB-C ports in portable monitors and docking stations. IC Role / Device Role / Timing Role: Standoff-clamp TVS located after Type-C CC logic but before USB PD controller VBUS switch. Use Value: Withstands 200 A IFSM (8.3 ms half-sine), surviving repeated hot-plug insertion surges without parametric shift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5AHE3/A | Same VBR (7.13–7.88 V), lower PPPM = 400 W, SMA package (smaller thermal mass) | Not rated for AEC-Q101; limited to consumer/industrial use below 150 °C ambient | Select when board space is constrained and surge energy is ≤400 W (e.g., low-power IoT nodes) |
| TPSMC7.5AHE3_B/H | Identical electrical specs, same SMC package, HE3 suffix indicates RoHS+AEC-Q101 but not halogen-free | Acceptable for automotive use but lacks halogen-free compliance required by Tier 1 OEMs post-2025 | Choose if halogen-free is not mandated and cost optimization is prioritized over material compliance |
Compared with TPSMC7.5AHM3_B/H, SMAJ7.5AHE3/A offers smaller footprint but sacrifices 73% peak power handling and high-temp reliability; TPSMC7.5AHE3_B/H matches performance but omits halogen-free certification needed for new automotive platforms.

FAQ
What is the exact breakdown voltage tolerance for TPSMC7.5AHM3_B/H?
The TPSMC7.5AHM3_B/H has a guaranteed breakdown voltage range of 7.13 V to 7.88 V at 10 mA test current, with 7.50 V as the nominal value. This ±4.7% tolerance is measured per ANSI/IEEE C62.35 and remains stable across temperature due to its 0.052 %/°C VBR temperature coefficient. The TPSMC7.5AHM3_B/H maintains this spec under JEDEC JESD22-A108 stress testing.
Is TPSMC7.5AHM3_B/H certified for automotive use?
Yes, TPSMC7.5AHM3_B/H is AEC-Q101 qualified, as confirmed by Vishay's documentation (Document Number 88407, Revision 19-Jan-2024). The HM3 suffix explicitly denotes halogen-free, RoHS-compliant, and AEC-Q101 qualified construction. It passes all required stress tests including HTRB, HTGB, and temperature cycling for automotive under-hood deployment.
What is the maximum clamping voltage of TPSMC7.5AHM3_B/H at rated surge current?
The TPSMC7.5AHM3_B/H exhibits a maximum clamping voltage (VC) of 11.3 V when subjected to its rated 133 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured per Fig. 1 in the datasheet and ensures protected circuits remain below critical overvoltage thresholds during transient events.
Does TPSMC7.5AHM3_B/H support lead-free reflow assembly?
Yes, TPSMC7.5AHM3_B/H is rated for lead-free reflow with a maximum peak temperature of 260 °C and meets MSL Level 1 per J-STD-020. Its matte tin-plated terminals are solderable per J-STD-002 and JESD22-B102, and it passes JESD201 Class 2 whisker testing - confirming robust manufacturability in modern SMT lines without pre-baking.
How does TPSMC7.5AHM3_B/H differ from TPSMC7.5AHE3_B/H?
The TPSMC7.5AHM3_B/H and TPSMC7.5AHE3_B/H share identical electrical specifications and SMC packaging, but differ in material compliance: HM3 denotes halogen-free + RoHS + AEC-Q101, whereas HE3 is RoHS + AEC-Q101 only. Both are functionally interchangeable in circuit design, but TPSMC7.5AHM3_B/H satisfies stricter OEM material declarations for new automotive platforms.
