Product details
Overview
P6SMB82AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 82 V breakdown voltage (VBR = 77.9–86.1 V at IT = 1.0 mA), 113 V maximum clamping voltage (VC) at 5.3 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 µs waveform). It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and ESD in industrial and automotive electronics.
For engineers reviewing the P6SMB82AHM3/I datasheet, P6SMB82AHM3/I pinout, P6SMB82AHM3/I application, or P6SMB82AHM3/I equivalent, this device delivers verified clamping performance, AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, and MSL Level 1 moisture sensitivity - critical for high-reliability PCB assembly and automotive-grade surge protection design.
Technical Context
The P6SMB82AHM3/I operates as a unidirectional avalanche diode with cathode-band polarity marking, optimized for fast transient response (<1 ns) and low incremental surge resistance. Its glass-passivated junction ensures stable breakdown characteristics over temperature (-65 °C to +150 °C).
It is designed for mounting on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, delivering 600 W peak pulse power under standardized 10/1000 µs waveform conditions with 0.01% duty cycle. Thermal resistance is 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead).

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 VBR (80.8–89.2 V), same SMB package, 600 W rating, but commercial-grade (not AEC-Q101 qualified) | Lacks automotive qualification; suitable for industrial/commercial designs where AEC-Q101 is not mandated | Select when cost optimization is prioritized and automotive qualification is unnecessary |
| 1.5SMC82A | Same VBR range and clamping, but larger SMC (DO-214AB) package (7.11 mm × 6.22 mm), higher thermal mass | Requires larger PCB footprint and different pad layout; better suited for higher average power dissipation scenarios | Choose when board space allows and enhanced thermal performance under repetitive surges is required |
Compared with SMAJ85A-E3/5B and 1.5SMC82A, the P6SMB82AHM3/I uniquely combines AEC-Q101 qualification, halogen-free construction, and compact SMB footprint - making it optimal for space-constrained, automotive-grade designs requiring traceable compliance and zero rework risk in reflow assembly.

FAQ
What is the maximum clamping voltage of the P6SMB82AHM3/I under standard test conditions?
The P6SMB82AHM3/I has a maximum clamping voltage (VC) of 113 V at 5.3 A peak pulse current (IPPM) using the 10/1000 µs waveform. This value is measured per JEDEC standards and reflects the actual voltage imposed on the protected circuit during a defined surge event. The P6SMB82AHM3/I maintains this clamping performance across its specified operating temperature range and is validated for repeatable operation in automotive environments.
Is the P6SMB82AHM3/I suitable for automotive applications?
Yes, the P6SMB82AHM3/I is AEC-Q101 qualified (indicated by the HM3 suffix), meaning it has passed stress tests for temperature cycling, humidity, mechanical shock, and surge endurance required for automotive electronic components. Its halogen-free, RoHS-compliant construction and MSL Level 1 rating further support use in engine control, body electronics, and ADAS sensor modules where reliability and process compatibility are mandatory. The P6SMB82AHM3/I meets these criteria without derating.
What does the "HM3" suffix signify in P6SMB82AHM3/I?
The "HM3" suffix in P6SMB82AHM3/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. Specifically, "H" indicates halogen-free molding compound, "M3" confirms RoHS compliance and JESD201 Class 2 whisker resistance, and the "/I" denotes packaging in 13-inch tape-and-reel (3200 units per reel). This full suffix ensures traceability to Vishay's automotive-grade manufacturing flow and material declarations required by Tier 1 suppliers. The P6SMB82AHM3/I is certified to these specifications per Vishay Document Number 88370.
How does the P6SMB82AHM3/I compare to bidirectional TVS diodes in the same series?
The P6SMB82AHM3/I is unidirectional and intended for DC-biased lines where polarity is fixed (e.g., power rails, grounded signal lines). Bidirectional variants like P6SMB82CA have symmetric clamping in both directions and are used for AC-coupled or floating signals (e.g., USB, RS-485). The P6SMB82AHM3/I offers lower leakage (<1.0 µA at 70.1 V) than bidirectional equivalents at the same standoff voltage and supports higher IFSM (100 A vs. N/A for bidirectional), making it preferable for high-current DC protection. Its cathode band also simplifies automated placement verification.
What is the thermal resistance and recommended pad layout for the P6SMB82AHM3/I?
The P6SMB82AHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead (RθJL) of 20 °C/W. Vishay specifies mounting on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 600 W pulse power. Pad dimensions must follow the DO-214AA outline: minimum 2.18 mm width, 1.52 mm length, with 5.59 mm overall reference length. Proper pad sizing ensures thermal stability during surge events and prevents solder joint fatigue. The P6SMB82AHM3/I's performance is validated only with this layout.
