Product details
Overview
P6SMB7.5AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on power and signal lines. It features a 7.13 V minimum breakdown voltage (VBR), 6.40 V standoff voltage (VWM), 11.3 V maximum clamping voltage at 53.1 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power rails.
For engineers reviewing the P6SMB7.5AHM3_A/I datasheet, P6SMB7.5AHM3_A/I pinout, P6SMB7.5AHM3_A/I application, or P6SMB7.5AHM3_A/I equivalent, key selection criteria include its AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, SMB (DO-214AA) package, unidirectional polarity with cathode band marking, and thermal resistance of 100 °C/W junction-to-ambient - critical for board-level surge protection design under repetitive transient stress.
Technical Context
This TVS diode operates as a clamping device that enters avalanche conduction when reverse voltage exceeds its 7.13–7.88 V breakdown range at 10 mA test current. Its low 11.3 V clamping voltage at 53.1 A ensures effective suppression of fast transients while limiting downstream component stress.
Designed for surface-mount assembly on 0.2" × 0.2" copper pads, it delivers 600 W peak pulse power per 10/1000 μs waveform with 0.01% duty cycle, and supports operating junction temperatures from –65 °C to +150 °C - validated for automotive-grade reliability per AEC-Q101.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.13 V / 7.88 V at 10 mA - defines precise avalanche onset threshold for repeatable clamping behavior |
| VWM | 6.40 V - maximum continuous reverse working voltage before leakage exceeds 500 μA |
| VC @ IPPM | 11.3 V at 53.1 A - clamped voltage during 600 W transient, directly limiting stress on protected ICs |
| IPPM | 53.1 A - peak pulse current capability under standardized 10/1000 μs waveform |
| PPPM | 600 W - surge energy handling capacity without degradation under defined pulse conditions |
| TJ max | +150 °C - enables operation in under-hood automotive and high-temperature industrial environments |
| RθJA | 100 °C/W - thermal resistance indicating required PCB copper area for safe power dissipation |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode identified by a single band on the body end.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A | Same VWM (6.4 V), but lower PPPM (400 W) and higher VC (12.0 V); SMA package (DO-214AC), larger footprint | Limited to lower-energy transients; less suitable for automotive load dump where 600 W margin is required | Select P6SMB7.5AHM3_A/I when 600 W rating, AEC-Q101 qualification, or SMB footprint is mandatory |
| 1.5SMC7.5A | Same VBR range and PPPM, but SMC (DO-214AB) package - 2.5 mm wider, higher RθJA (~120 °C/W) | Requires more PCB area; thermal performance inferior in dense layouts without added copper | Choose P6SMB7.5AHM3_A/I for space-constrained designs needing optimal thermal efficiency and automotive qualification |
Compared with SMAJ7.5A and 1.5SMC7.5A, the P6SMB7.5AHM3_A/I delivers superior surge margin (600 W), tighter clamping (11.3 V), AEC-Q101 validation, and optimized thermal resistance (100 °C/W) in the smallest standardized SMB footprint - making it the preferred choice for high-reliability automotive and industrial TVS placement.

FAQ
What is the breakdown voltage tolerance for P6SMB7.5AHM3_A/I?
The P6SMB7.5AHM3_A/I has a specified breakdown voltage (VBR) range of 7.13 V to 7.88 V at 10 mA test current, representing ±5% tolerance around the nominal 7.5 V rating. This tight distribution ensures predictable clamping onset across production lots and supports reliable design margining in safety-critical applications such as automotive power rails.
Is P6SMB7.5AHM3_A/I suitable for bidirectional transient protection?
No, P6SMB7.5AHM3_A/I is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. For bidirectional protection, Vishay offers the P6SMB7.5CA variant. Using P6SMB7.5AHM3_A/I in bidirectional configurations risks forward conduction during negative transients and invalidates its specified clamping performance.
Does P6SMB7.5AHM3_A/I meet automotive qualification standards?
Yes, P6SMB7.5AHM3_A/I is AEC-Q101 qualified, as confirmed by the "HM3" suffix denoting halogen-free, RoHS-compliant, and automotive-grade construction. It undergoes stress testing for temperature cycling, humidity, mechanical shock, and surge endurance - validating suitability for under-hood and chassis-mounted automotive electronics.
What is the maximum reverse leakage current for P6SMB7.5AHM3_A/I at rated VWM?
At its 6.40 V standoff voltage (VWM), the P6SMB7.5AHM3_A/I exhibits a maximum reverse leakage current (ID) of 500 μA at 25 °C. This low leakage preserves power efficiency in always-on circuits and avoids false triggering in high-impedance sensor bias networks.
How does the SMB package of P6SMB7.5AHM3_A/I compare thermally to larger packages like SMC?
The SMB (DO-214AA) package of P6SMB7.5AHM3_A/I provides a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W - lower than the ~120 °C/W of the larger SMC (DO-214AB) package. This allows more efficient heat dissipation in compact layouts, especially when mounted on 0.2" × 0.2" copper pads, supporting sustained operation near its 150 °C maximum junction temperature.
