Product details
Overview
TPSMB7.5A1BHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) diode designed for clamping inductive switching surges and lightning-induced transients on power rails and signal lines. It features a 7.5 V breakdown voltage (VBR), 6.4 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 11.3 V maximum clamping voltage at 53.1 A, and operates up to +185 °C junction temperature. It is used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the TPSMB7.5A1BHE3_A/I datasheet, TPSMB7.5A1BHE3_A/I pinout, TPSMB7.5A1BHE3_A/I application, or TPSMB7.5A1BHE3_A/I equivalent, this page delivers verified electrical parameters, SMB (DO-214AA) package details, AEC-Q101 qualification status, thermal derating curves, and direct alternative part comparisons - all grounded in Vishay's official 88406 document revision 23-Jan-2024.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with optimized junction passivation for stable clamping under high-temperature stress. Its unidirectional polarity enables forward-biased surge conduction only during overvoltage events above VBR, while maintaining low leakage (<250 µA at VWM) at 25 °C and <500 µA at 150 °C.
The device is rated for 75 A non-repetitive forward surge current (8.3 ms half-sine), exhibits 0.052 %/°C temperature coefficient of VBR, and meets J-STD-020 MSL Level 1 with 260 °C reflow peak - confirming suitability for automated SMT assembly in automotive-grade production.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 7.13 / 7.50 / 7.88 V - ensures reliable turn-on before downstream IC damage thresholds |
| VWM | 6.4 V - blocks normal operating voltage while allowing margin for ripple and tolerance |
| VC @ IPPM | 11.3 V - clamps transient energy to safe levels for 3.3 V or 5 V logic and power stages |
| PPPM | 600 W (10/1000 µs) - handles typical load-dump and ISO 7637-2 pulse 5a surges |
| IFSM | 75 A (8.3 ms half-sine) - withstands repetitive motor-switching or relay-coil turn-off spikes |
| TJ max | +185 °C - supports under-hood automotive placement without thermal derating penalties |
| Leakage @ VWM | 250 µA @ 25 °C - minimizes standby power loss in battery-critical systems |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, matte tin-plated terminals, cathode indicated by color band. Dimensions: 4.06 mm × 3.30 mm × 2.20 mm (L × W × H). Complies with UL 94 V-0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry during reverse-biased clamping | Connected to protected line (e.g., VIN or signal); conducts surge current to ground path |
| Cathode | Current exit during reverse-biased clamping | Connected to system ground or low-impedance return; defines unidirectional conduction direction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including HTGB, HTRB, and TCT |
| Junction passivation | Reduces parameter drift and leakage increase after prolonged high-temperature operation |
| MSL Level 1 rating | Enables single-pass reflow without baking; compatible with standard SMT lines up to 260 °C peak |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ESD or inductive kick) |
| 185 °C TJ capability | Eliminates need for external thermal derating in engine control units and power inverters |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Clamping |
|---|---|
Use Scenario: Protecting 12 V supply inputs in body control modules against ISO 7637-2 pulse 5a load dump transients. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between VBAT and GND to clamp surges >11.3 V within nanoseconds. Use Value: Prevents latch-up or gate oxide rupture in downstream DC/DC converters and microcontrollers during cold-crank or alternator regulation faults. |
Use Scenario: Shielding analog sensor outputs (e.g., pressure or temperature sensors) from ESD and cable discharge events in factory automation. IC Role / Device Role / Timing Role: Low-capacitance TVS connected across differential signal pair to shunt transients before op-amp input stage. Use Value: Maintains signal integrity below 11.3 V clamping level while adding <1 nA leakage at 6.4 V, preserving measurement accuracy. |
| Consumer Power Adapter Surge Suppression | Telecom DC Input Line Protection |
Use Scenario: Safeguarding AC/DC adapter secondary-side 5 V or 9 V outputs from transient coupling via shared mains wiring. IC Role / Device Role / Timing Role: Standoff-rated TVS mounted at output connector to absorb fast-rising line-to-ground surges. Use Value: Enables compliance with IEC 61000-4-5 Level 3 (1 kV/2 Ω) without increasing board area beyond SMB footprint. |
Use Scenario: Securing -48 V DC telecom power inputs against lightning-induced longitudinal surges on copper distribution lines. IC Role / Device Role / Timing Role: Unidirectional TVS configured anode-to-line, cathode-to-ground to clamp negative-going surges. Use Value: Withstands 75 A surge current and maintains <11.3 V clamping at full rating - critical for protecting PoE controllers and line cards. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A | Lower PPPM (400 W), same SMB package, VBR = 7.22–7.98 V, VC = 12.0 V @ 32.5 A | Not AEC-Q101 qualified; suitable for commercial-grade consumer products only | Select when cost sensitivity outweighs automotive qualification and 600 W surge headroom |
| SMCJ7.5A | Higher PPPM (1500 W), larger SMC (DO-214AB) package, VC = 12.9 V @ 116 A, same VBR range | Requires PCB layout change; preferred for higher-energy industrial surge standards (IEC 61000-4-5 Level 4) | Choose when system-level testing requires >1 kV/2 Ω immunity and board space permits larger footprint |
Compared with SMAJ7.5A and SMCJ7.5A, the TPSMB7.5A1BHE3_A/I uniquely balances AEC-Q101 qualification, 600 W surge capacity, and SMB footprint - making it optimal for space-constrained automotive ECUs where reliability and manufacturability must coexist.

FAQ
What is the exact breakdown voltage range for TPSMB7.5A1BHE3_A/I?
The TPSMB7.5A1BHE3_A/I has a guaranteed breakdown voltage (VBR) range of 7.13 V (minimum) to 7.88 V (maximum) at 10 mA test current, with a nominal value of 7.50 V. This specification is confirmed in Vishay's Document Number 88406, Table on page 2, and applies directly to the TPSMB7.5A1BHE3_A/I variant with HE3 suffix and revision code A.
Is TPSMB7.5A1BHE3_A/I AEC-Q101 qualified?
Yes, TPSMB7.5A1BHE3_A/I is AEC-Q101 qualified. The HE3 suffix explicitly denotes RoHS-compliant and AEC-Q101-qualified construction, as stated in the "MECHANICAL DATA" section of Vishay's 88406 datasheet. This qualification covers high-temperature operating life, temperature cycling, and unbiased high-temperature storage tests required for automotive electronics.
What does the "1B" in TPSMB7.5A1BHE3_A/I signify?
The "1B" in TPSMB7.5A1BHE3_A/I is the device marking code per Vishay's ordering convention - corresponding to the KGP marking shown in the Electrical Characteristics table for TPSMB7.5A. It identifies the specific breakdown voltage bin and manufacturing lot traceability, not a functional variant. All TPSMB7.5A devices with HE3 suffix share identical electrical specs regardless of "1B" or other marking codes.
What is the maximum clamping voltage of TPSMB7.5A1BHE3_A/I at rated surge current?
The maximum clamping voltage (VC) of TPSMB7.5A1BHE3_A/I is 11.3 V at its peak pulse current (IPPM) of 53.1 A, measured using the 10/1000 µs waveform. This value is specified in the Electrical Characteristics table on page 2 of Vishay Document 88406 and defines the upper voltage limit imposed on protected circuits during worst-case surge events.
Does TPSMB7.5A1BHE3_A/I have bidirectional polarity?
No, TPSMB7.5A1BHE3_A/I is unidirectional only. The datasheet explicitly states "Available in unidirectional polarity only" under FEATURES, and the device uses anode/cathode terminal configuration with cathode marked by a band. Bidirectional variants (e.g., TPSMB7.5CA) are separate part numbers and are not functionally interchangeable with TPSMB7.5A1BHE3_A/I.
