Overview
P6SMB7.5AHM3_B/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 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 (IPPM), and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6SMB7.5AHM3_B/I datasheet, P6SMB7.5AHM3_B/I pinout, P6SMB7.5AHM3_B/I application, or P6SMB7.5AHM3_B/I equivalent, this AEC-Q101 qualified, halogen-free, RoHS-compliant TVS diode delivers verified clamping performance, low incremental surge resistance, and fast response time for robust overvoltage protection in space-constrained PCB layouts.
Technical Context
The P6SMB7.5AHM3_B/I operates as a unidirectional avalanche diode with glass-passivated junction, optimized for transient suppression in DC power rails and low-voltage signal paths. Its 600 W peak pulse power rating is specified under 10/1000 µs waveform at 0.01% duty cycle, with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead).
It exhibits 0.061 %/°C temperature coefficient of VBR, 5.0 W steady-state power dissipation, and 100 A non-repetitive forward surge current (IFSM). The device is rated for -65 °C to +150 °C operating junction temperature and meets MSL level 1 per J-STD-020 with 260 °C reflow peak.

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-E3/5B | Same SMB package, 7.13–7.88 V VBR, but 400 W PPPM and non-AEC-Q101 rated. | Limited to commercial-grade consumer or office equipment; not qualified for automotive temperature cycling or humidity testing. | Select when cost sensitivity outweighs automotive qualification requirements and surge energy remains ≤400 W. |
| 1.5SMC7.5A | Higher-power SMC package (1500 W PPPM), same VWM/VBR range, but 2.5× larger footprint and higher thermal mass. | Suitable for high-energy industrial AC mains inputs or DC link protection where PCB space allows larger case. | Choose only if system-level surge testing exceeds 600 W or thermal dissipation requires lower RθJA than SMB permits. |
Compared with SMAJ7.5A-E3/5B and 1.5SMC7.5A, the P6SMB7.5AHM3_B/I uniquely balances AEC-Q101 compliance, 600 W surge capacity, and SMB footprint-making it optimal for automotive and space-constrained industrial designs requiring validated reliability without layout redesign.

FAQ
What is the clamping voltage of P6SMB7.5AHM3_B/I at its rated peak pulse current?
The P6SMB7.5AHM3_B/I has a maximum clamping voltage (VC) of 11.3 V at 53.1 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is measured per JEDEC standards and ensures downstream ICs see no more than 11.3 V during a full 600 W transient event. The P6SMB7.5AHM3_B/I maintains this clamping performance across its qualified temperature range (-65 °C to +150 °C) with minimal drift due to its 0.061 %/°C VBR coefficient.
Is P6SMB7.5AHM3_B/I suitable for automotive applications?
Yes, the P6SMB7.5AHM3_B/I is AEC-Q101 qualified, as confirmed by its HM3 suffix and documentation in Vishay's P6SMB datasheet revision 09-Jan-2024. It undergoes stress testing including temperature cycling, high-temperature reverse bias (HTRB), and ESD per AEC-Q101 requirements. The P6SMB7.5AHM3_B/I is deployed in automotive body control modules, lighting controllers, and sensor interfaces where sustained operation at 150 °C junction temperature and immunity to load-dump transients are mandatory.
What does the "_B/I" suffix indicate in P6SMB7.5AHM3_B/I?
The "_B" denotes AEC-Q101 qualification for the P6SMB7.5AHM3_B/I, specifically for devices in the 6.8 V to 220 V VWM range. The "/I" indicates packaging in 13-inch diameter plastic tape and reel, with 3200 units per reel - optimized for high-volume SMT placement. The "HM3" portion confirms halogen-free, RoHS-compliant construction per Vishay's material categorization standard.
How does P6SMB7.5AHM3_B/I compare to bidirectional TVS diodes like P6SMB7.5CA?
The P6SMB7.5AHM3_B/I is unidirectional and intended for DC rail protection where polarity is fixed (e.g., 5 V supply to ground), offering lower leakage and tighter VBR tolerance than its bidirectional counterpart P6SMB7.5CA. The P6SMB7.5CA supports AC or floating signal lines but exhibits higher leakage and symmetric clamping in both directions. Use P6SMB7.5AHM3_B/I when protecting polarized circuits with defined ground reference and strict leakage budgets.
What is the thermal resistance of P6SMB7.5AHM3_B/I, and how does it affect PCB layout?
The P6SMB7.5AHM3_B/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 on 0.2" × 0.2" copper pads per datasheet Fig. 2. To maintain safe junction temperatures under repetitive surges, PCB layout must use minimum recommended pad dimensions (0.086" × 0.060") and avoid excessive copper isolation. The P6SMB7.5AHM3_B/I's low RθJL enables effective heat transfer to PCB traces, reducing reliance on large thermal vias in compact designs.
