Product details
Overview
P6SMB82A-E3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power 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 - deployed in automotive sensor interfaces, industrial I/O modules, and DC power rail protection.
For engineers reviewing the P6SMB82A-E3/5B datasheet, P6SMB82A-E3/5B pinout, P6SMB82A-E3/5B application, or P6SMB82A-E3/5B equivalent, this page delivers verified electrical parameters, SMB (DO-214AA) package details, clamping performance under surge conditions, thermal derating behavior, and AEC-Q101-qualified alternatives for automotive-grade design-in.
Technical Context
This unidirectional TVS diode operates as a shunt-clamping device that remains high-impedance below VWM (70.1 V) and rapidly transitions to low-impedance conduction above VBR (min. 77.9 V) to limit transient voltages. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and repeatable breakdown characteristics across temperature.
Designed for automated SMT assembly on standard PCB pads (0.2" × 0.2"), it delivers 600 W peak pulse power handling with 10/1000 μs waveform at ≤0.01% duty cycle, and exhibits a 0.105 %/°C temperature coefficient of VBR, enabling predictable clamping behavior from −65 °C to +150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 70.1 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC/AC working margin. |
| VBR (Breakdown) | 77.9–86.1 V at 1 mA - Confirmed avalanche onset range; ensures reliable triggering above normal operating voltage. |
| VC (Clamping) | 113 V at 5.3 A (10/1000 μs) - Peak voltage seen by protected circuit during worst-case surge; critical for downstream IC survival. |
| PPPM | 600 W - Surge energy absorption capacity per pulse; supports repetitive transients up to 0.01% duty cycle. |
| IPPM | 5.3 A - Peak pulse current capability at rated clamping voltage; determines minimum trace width and layout robustness. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive or high-ambient industrial environments. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; informs thermal management requirements. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads; meets UL 94 V-0 flammability and JESD201 Class 2 whisker resistance. Cathode indicated by band on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference | Connected to lower-potential side (e.g., GND or return path); defines polarity-sensitive placement in unidirectional configuration. |
| Cathode | Reverse voltage input / Clamping node | Connected to protected line (e.g., 24 V rail or signal input); conducts surge current to ground when VAK exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power | Enables protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) on 24 V systems without cascaded devices. |
| Glass-passivated junction | Ensures long-term stability of VBR and leakage under thermal cycling and humidity stress (J-STD-020 MSL level 1). |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ISO 7637-2 pulse 1/2a), improving system immunity margin. |
| AEC-Q101 qualified option | Available as P6SMB82AHE3_B (suffix _B) for automotive applications requiring validated reliability per stress test standards. |
| RoHS-compliant, halogen-free variants | E3 suffix indicates commercial-grade RoHS compliance; M3 suffix adds halogen-free molding compound for green manufacturing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ82A-E3/5B | Same VWM/VBR/VC specs but in SMA (DO-214AC) package; 10% smaller footprint, 20% lower PPPM (400 W). | Limited to lower-energy transients (IEC 61000-4-5 Level 2); unsuitable for automotive load dump or industrial 4 kV testing. | Select when board space is constrained and surge threat level is moderate (e.g., consumer USB power ports). |
| P6SMB82AHM3_B | Identical electrical specs and SMB package; adds AEC-Q101 qualification and halogen-free construction. | Required for automotive OEM designs needing certified reliability; not necessary for commercial/industrial use. | Choose for Tier-1 automotive programs where qualification documentation and extended lifetime validation are mandatory. |
Compared with P6SMB82A-E3/5B, SMAJ82A-E3/5B trades surge robustness for compactness, while P6SMB82AHM3_B retains full 600 W capability with added automotive qualification - making the latter a drop-in upgrade for automotive BOMs without layout change.

FAQ
What is the maximum clamping voltage of the P6SMB82A-E3/5B under a 10/1000 μs surge?
The P6SMB82A-E3/5B has a maximum clamping voltage (VC) of 113 V when subjected to its rated peak pulse current of 5.3 A with a 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88370 and defines the upper voltage limit imposed on protected circuitry during standardized surge events. The P6SMB82A-E3/5B maintains this clamping performance across its specified operating temperature range.
Is the P6SMB82A-E3/5B suitable for automotive applications?
The base P6SMB82A-E3/5B is commercial-grade and RoHS-compliant but not AEC-Q101 qualified. For automotive use, Vishay offers the P6SMB82AHE3_B variant (with suffix _B), which shares identical electrical specs and SMB packaging while meeting AEC-Q101 stress test requirements. The P6SMB82A-E3/5B itself is appropriate for non-safety-critical aftermarket or industrial-adjacent automotive subsystems where formal qualification is not mandated.
What is the thermal resistance of the P6SMB82A-E3/5B, and how does it affect PCB layout?
The P6SMB82A-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimal copper area; increasing pad size or adding internal ground planes reduces RθJA and improves surge endurance. Layout must follow Vishay's recommended mounting pad dimensions in Document 88370 to achieve rated 600 W pulse power without thermal runaway.
How does the P6SMB82A-E3/5B differ from bidirectional TVS diodes like P6SMB82CA?
The P6SMB82A-E3/5B is unidirectional and functions only in reverse-bias mode, with polarity marked by a cathode band; it blocks forward current beyond ~3.5 V. In contrast, P6SMB82CA is bidirectional, offering symmetric clamping in both directions with no polarity marking. The P6SMB82A-E3/5B is selected for DC supply rail protection where polarity is fixed, while P6SMB82CA suits AC lines or differential data buses like RS-485 where voltage reversals occur.
What is the leakage current specification for the P6SMB82A-E3/5B at its stand-off voltage?
The P6SMB82A-E3/5B exhibits a maximum reverse leakage current (ID) of 1.0 μA at its stand-off voltage (VWM) of 70.1 V and TA = 25 °C. This low leakage ensures minimal power loss and avoids false triggering in high-impedance sensing circuits. Leakage increases with temperature but remains below 10 μA up to +85 °C, as confirmed by Vishay's derating curves in Document 88370.
