Product details
Overview
P6SMB82AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 70.1 V stand-off voltage (VWM), 77.9–86.1 V breakdown voltage (VBR) at 1 mA, 113 V maximum clamping voltage (VC) at 5.3 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the P6SMB82AHM3/H datasheet, P6SMB82AHM3/H pinout, P6SMB82AHM3/H application, or P6SMB82AHM3/H equivalent, this device serves as a halogen-free, RoHS-compliant, AEC-Q101-qualified transient suppressor optimized for automotive and industrial systems requiring reliable surge immunity on 72 V nominal bus lines, sensor interfaces, and MOSFET gate drivers.
Technical Context
The P6SMB82AHM3/H operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its specified VBR range (77.9–86.1 V), thereby clamping transients to ≤113 V at 5.3 A. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 µA at 70.1 V).
Thermally, it exhibits RθJA = 100 °C/W and RθJL = 20 °C/W, enabling operation up to +150 °C junction temperature. The device meets MSL Level 1 per J-STD-020 and supports reflow soldering with peak temperature up to 260 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 70.1 V - Maximum continuous reverse operating voltage before conduction begins; defines safe DC working margin for 72 V systems. |
| VBR @ IT = 1 mA | 77.9–86.1 V - Measured breakdown threshold; ensures consistent triggering across production lots under standardized test conditions. |
| VC @ IPPM = 5.3 A | 113 V - Clamped voltage during 10/1000 µs surge; limits downstream component stress during 600 W transient events. |
| IPPM | 5.3 A - Peak pulse current capability; determines survivability against defined lightning or EFT surges per IEC 61000-4-5. |
| PPPM | 600 W - Peak pulse power rating with 10/1000 µs waveform; validates energy absorption capacity for repetitive surge duty cycles. |
| TJ max. | +150 °C - Maximum junction temperature; supports operation in under-hood automotive environments and high-ambient industrial enclosures. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 0.220" × 0.130" footprint; compatible with automated pick-and-place and reflow processes. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; cathode indicated by band marking on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference | Connected to system ground or lower-potential rail; establishes polarity-sensitive clamping direction. |
| Cathode | Reverse voltage input / Clamping output | Connected to protected line (e.g., 72 V supply); conducts avalanche current to anode during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ85A-E3/5B | Higher VWM = 72.2 V, VBR = 85–94.4 V, VC = 125 V at 4.8 A; same SMB package but non-AEC-Q101 rated. | Commercial-grade only; unsuitable for automotive qualification requirements. | Select when AEC-Q101 compliance is not required and higher clamping voltage is acceptable for system margin. |
| 1.5SMC82A | Same VWM/VBR/VC specs but in larger SMC (DO-214AB) package; 1.5 kW peak power rating. | Requires larger PCB area and different thermal layout; suited for higher-energy surge environments. | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4 and additional energy headroom is needed. |
Compared with SMAJ85A-E3/5B and 1.5SMC82A, the P6SMB82AHM3/H uniquely combines AEC-Q101 qualification, halogen-free construction, and precise 70.1 V stand-off in the compact SMB footprint-making it optimal for space-constrained, automotive-grade designs where regulatory compliance and material content are mandatory.

FAQ
What is the maximum clamping voltage of the P6SMB82AHM3/H under standard test conditions?
The P6SMB82AHM3/H has a maximum clamping voltage (VC) of 113 V when subjected to its rated peak pulse current of 5.3 A using a 10/1000 µs waveform. This value is measured per JEDEC standards and reflects worst-case voltage seen by downstream components during surge events, ensuring compatibility with 120 V-rated ICs and MOSFETs in the protected circuit.
Is the P6SMB82AHM3/H suitable for automotive applications?
Yes, the P6SMB82AHM3/H is AEC-Q101 qualified and specifically designated for automotive use via the "HM3" suffix (halogen-free, RoHS-compliant, and AEC-Q101 qualified). It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and mechanical shock per JESD22, making it appropriate for engine control units, body electronics, and ADAS power domains.
What does the "H" suffix indicate in P6SMB82AHM3/H?
The "H" suffix in P6SMB82AHM3/H denotes the packaging configuration: 7-inch diameter plastic tape and reel, with 750 units per reel. This format is optimized for high-speed SMT placement equipment and aligns with industry-standard logistics for volume manufacturing of automotive and industrial electronics.
How does the P6SMB82AHM3/H compare to bidirectional TVS diodes in the same series?
The P6SMB82AHM3/H is unidirectional, meaning it protects only against positive-going transients on the cathode side relative to anode (ground). Bidirectional variants like P6SMB82CA have symmetric clamping in both polarities and lack polarity marking. Use P6SMB82AHM3/H where DC bias polarity is fixed and negative transients are not expected-common in 72 V battery systems and regulated DC supplies.
What is the thermal resistance from junction to ambient for the P6SMB82AHM3/H?
The P6SMB82AHM3/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the minimum recommended 0.2" × 0.2" copper pads per terminal. This value assumes standard FR-4 PCB layout and natural convection cooling; actual thermal performance improves with enhanced copper pour or forced airflow.
