Product details
Overview
P6SMB82AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, 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 capability with a 10/1000 μs waveform - deployed in automotive-grade industrial power supplies and sensor interfaces.
For engineers reviewing the P6SMB82AHM3_A/I datasheet, P6SMB82AHM3_A/I pinout, P6SMB82AHM3_A/I application, or P6SMB82AHM3_A/I equivalent, this part serves as a halogen-free, AEC-Q101-qualified TVS for high-reliability 12–48 V systems requiring low-leakage (<1 μA), fast-response transient suppression with MSL Level 1 reflow compatibility and 150 °C junction temperature rating.
Technical Context
This device operates as a unidirectional avalanche diode, conducting only during reverse overvoltage events while remaining high-impedance under normal bias. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance, enabling precise clamping within ±5% tolerance across temperature.
The P6SMB82AHM3_A/I is rated for repetitive 10/1000 μs transients at 0.01% duty cycle and supports surge currents up to 5.3 A without degradation. Its thermal resistance (RθJA = 100 °C/W) and junction-to-lead resistance (RθJL = 20 °C/W) are optimized for PCB pad-limited SMB (DO-214AA) mounting per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 70.1 V - Maximum continuous reverse operating voltage before leakage exceeds 1 μA; defines safe DC rail margin. |
| VBR (Breakdown) | 77.9–86.1 V at 1 mA - Tight 5% tolerance window ensures predictable turn-on during transients. |
| VC (Clamping) | 113 V at 5.3 A IPPM - Limits downstream voltage stress during 600 W surge events. |
| PPPM | 600 W - Peak pulse power handling with 10/1000 μs waveform; validated for automotive load-dump immunity. |
| Leakage (ID) | <1 μA at VWM - Minimizes standby power loss in battery-backed or low-power sensor circuits. |
| TJ max. | 150 °C - Enables operation in under-hood automotive environments and enclosed industrial enclosures. |
| Package | SMB (DO-214AA) - Low-profile SMD footprint (4.57 × 3.94 × 2.20 mm) compatible with automated placement and IPC-7351B land patterns. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, unidirectional polarity marked by cathode band. Matte tin-plated leads meet J-STD-002 solderability and JESD22-B102 whisker resistance Class 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., GND or return path); conducts during forward surge (IFSM = 100 A). |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 48 V rail); avalanches when reverse voltage exceeds VBR, shunting surge to ground. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive electronics per stress test requirements - supports under-hood ECU, ADAS camera, and infotainment power rails. |
| Halogen-free & RoHS-compliant (HM3) | Meets IEC 61249-2-21 and JEDEC J-STD-020 MSL Level 1 - enables lead-free reflow at 260 °C peak without delamination. |
| 600 W peak pulse power | Withstands ISO 7637-2 Pulse 1/2a/5a transients and IEC 61000-4-5 Level 4 surges on 24–48 V systems without derating. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage overshoot during fast transients - critical for protecting 75 V-rated MOSFETs and CAN transceivers. |
| 1 μA max reverse leakage @ VWM | Preserves efficiency in always-on circuits (e.g., telematics wake-up receivers) and avoids false triggering in high-impedance sensing nodes. |

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 | Higher VWM (72.2 V), same SMB package, non-AEC-Q101, standard RoHS (E3 suffix) | Lacks automotive qualification and halogen-free certification; suitable for commercial-grade telecom or computing power rails. | Select when AEC-Q101 and halogen-free compliance are not required; verify layout compatibility with identical SMB footprint. |
| 1.5SMC82A | Same VWM/VBR specs, higher RθJA (125 °C/W), DO-214AB (SMC) package (larger footprint) | Requires larger PCB area and different land pattern; better thermal dissipation in non-space-constrained designs. | Choose for cost-sensitive industrial applications where board space permits larger SMC package and automotive grade is unnecessary. |
Compared with SMAJ85A and 1.5SMC82A, the P6SMB82AHM3_A/I uniquely combines AEC-Q101 qualification, halogen-free construction, and SMB footprint - making it the only option among the three qualified for automotive Tier-1 power supply designs requiring zero material exemptions and MSL Level 1 assembly.

FAQ
What is the maximum clamping voltage of P6SMB82AHM3_A/I at its rated peak pulse current?
The P6SMB82AHM3_A/I has a maximum clamping voltage (VC) of 113 V at 5.3 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured under standardized test conditions per JEDEC and ensures predictable overvoltage limiting for protected ICs and MOSFETs downstream of the P6SMB82AHM3_A/I.
Is P6SMB82AHM3_A/I suitable for automotive applications?
Yes, P6SMB82AHM3_A/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant, and automotive-grade construction. It is explicitly rated for under-hood environments with TJ max = 150 °C and validated for repetitive surge stress - making it appropriate for engine control units, ADAS cameras, and body electronics using the P6SMB82AHM3_A/I.
What does the "_A/I" suffix mean in P6SMB82AHM3_A/I?
The "_A/I" suffix in P6SMB82AHM3_A/I indicates packaging: "A" denotes the revision code (per Vishay's ordering nomenclature), and "I" specifies 13-inch diameter plastic tape-and-reel delivery containing 3200 units. This matches the documented ordering format for AEC-Q101 HM3 variants in the P6SMB series datasheet.
How does P6SMB82AHM3_A/I differ from the standard P6SMB82A-E3 variant?
The P6SMB82AHM3_A/I differs from P6SMB82A-E3 in three key ways: it uses halogen-free molding compound (HM3 vs. E3), is AEC-Q101 qualified (vs. commercial grade), and ships in 13″ tape-and-reel (I) rather than 7″ (H). Electrically and dimensionally, both share identical VWM, VBR, VC, and SMB package - but only the P6SMB82AHM3_A/I meets automotive material and reliability requirements.
What is the reverse leakage current specification for P6SMB82AHM3_A/I at its stand-off voltage?
The P6SMB82AHM3_A/I exhibits a maximum reverse leakage current (ID) of 1 μA at its rated stand-off voltage (VWM) of 70.1 V and ambient temperature of 25 °C. This ultra-low leakage preserves power efficiency in always-on circuits and prevents false triggering in high-impedance monitoring paths where the P6SMB82AHM3_A/I is deployed.
