Product details
Overview
P6SMB7.5AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 6.40 V stand-off voltage (VWM), 7.13–7.88 V breakdown voltage (VBR) at 10 mA, 11.3 V maximum clamping voltage (VC) at 53.1 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor protection and industrial I/O interface circuits.
For engineers reviewing the P6SMB7.5AHM3/I datasheet, P6SMB7.5AHM3/I pinout, P6SMB7.5AHM3/I application, or P6SMB7.5AHM3/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification (HM3 suffix), 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a clamping device that remains non-conductive below its 6.40 V stand-off voltage and rapidly transitions to low-impedance conduction when transient overvoltage exceeds its 7.13–7.88 V breakdown threshold. Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns).
The device delivers 11.3 V clamping voltage at 53.1 A peak pulse current under 10/1000 μs waveform, with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead). It meets J-STD-020 MSL Level 1 and JESD201 Class 2 whisker resistance requirements.

Use Scenario: Secondary-side overvoltage suppression on 5 V/9 V USB-C PD adapter outputs subject to no-load regulation overshoot and ESD events. IC Role / Device Role: Unidirectional clamping diode between VOUT and GND, sized to handle 600 W pulses without thermal runaway. Use Value: Prevents damage to connected devices during transient overvoltage conditions while supporting full 5.0 W steady-state power dissipation capability. |
Use Scenario: Front-end protection for RS-485 transceivers in base station backhaul links exposed to lightning-induced surges on twisted-pair lines. IC Role / Device Role: Primary-stage TVS on differential pair (A/B lines), used in conjunction with common-mode chokes and secondary-stage MOVs. Use Value: Clamps common-mode transients to ≤11.3 V before they reach the transceiver's ±15 kV ESD-rated inputs, reducing failure rate in outdoor deployments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.0A | Lower VWM (6.0 V), higher VC (12.0 V at 49.2 A), same SMB package and 600 W rating. | Marginally tighter stand-off tolerance but reduced clamping efficiency; less suitable for 5 V systems requiring strict <12 V clamping. | Select only if system tolerates higher clamping voltage and requires tighter VWM match to 5 V rail. |
| 1.5SMC7.5A | Same VWM/VBR/VC specs, but larger SMC (DO-214AB) package (7.11 mm × 6.22 mm); 1.5 kW rating (derated to 600 W at TA = 25 °C). | Requires PCB layout change; better thermal performance but incompatible with space-constrained SMB footprints. | Choose only when board real estate allows larger package and enhanced thermal headroom is prioritized over miniaturization. |
Compared with SMAJ7.0A and 1.5SMC7.5A, the P6SMB7.5AHM3/I offers optimal balance of AEC-Q101 qualification, SMB footprint compatibility, and 11.3 V clamping - making it preferred for automotive and high-density industrial designs where reliability, size, and precise voltage coordination are jointly critical.

FAQ
What is the maximum clamping voltage of the P6SMB7.5AHM3/I under rated surge conditions?
The P6SMB7.5AHM3/I exhibits a maximum clamping voltage (VC) of 11.3 V when subjected to its rated peak pulse current of 53.1 A using the standard 10/1000 μs waveform. This value is measured at TJ = 25 °C with device mounted on 0.2" × 0.2" copper pads per JEDEC standards. The P6SMB7.5AHM3/I maintains this clamping performance across its operational temperature range, making it suitable for protecting 5 V logic interfaces.
Is the P6SMB7.5AHM3/I qualified for automotive applications?
Yes, the P6SMB7.5AHM3/I carries the HM3 suffix, indicating halogen-free, RoHS-compliant construction and full AEC-Q101 qualification. It has passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per AEC-Q101 Rev D. The P6SMB7.5AHM3/I is approved for use in automotive subsystems such as body control modules, infotainment power rails, and ADAS sensor signal conditioning.
What does the "I" suffix in P6SMB7.5AHM3/I indicate?
The "I" suffix in P6SMB7.5AHM3/I specifies the packaging configuration: 13-inch diameter plastic tape and reel, containing 3200 units per reel. This format supports high-volume automated pick-and-place assembly. The "HM3" portion denotes halogen-free, RoHS-compliant materials and AEC-Q101 qualification, while "A" confirms unidirectional polarity and "7.5" designates the nominal breakdown voltage family.
How does the P6SMB7.5AHM3/I compare to bidirectional TVS diodes in the same series?
The P6SMB7.5AHM3/I is unidirectional and intended for DC-biased lines like power rails or single-ended signals referenced to ground. Bidirectional variants (e.g., P6SMB7.5CA) lack polarity markings and suppress transients in both directions - suitable for AC lines or differential pairs. The P6SMB7.5AHM3/I provides lower leakage at VWM (≤500 μA vs. ≤1000 μA for CA types) and is optimized for asymmetric voltage environments.
What is the thermal resistance profile of the P6SMB7.5AHM3/I?
The P6SMB7.5AHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead resistance (RθJL) of 20 °C/W, measured under standard JEDEC test conditions (0.2" × 0.2" copper pads). These values enable reliable operation at 5.0 W steady-state power dissipation up to +50 °C ambient, with derating above that temperature per Figure 2 in the datasheet. The P6SMB7.5AHM3/I's low RθJL supports effective heat transfer to PCB copper planes during transient events.
