Product details
Overview
P6SMB82A-E3/52 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 standoff 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 ECUs, industrial I/O modules, and DC power rail protection.
For engineers reviewing the P6SMB82A-E3/52 datasheet, P6SMB82A-E3/52 pinout, P6SMB82A-E3/52 application, or P6SMB82A-E3/52 equivalent, key selection considerations include its SMB (DO-214AA) package compatibility, unidirectional polarity with cathode band marking, AEC-Q101 qualification eligibility (via HE3/HM3 variants), and thermal resistance (RθJA = 100 °C/W) under standard PCB pad layout.
Technical Context
The P6SMB82A-E3/52 operates as a clamping-type TVS diode, leveraging an avalanche breakdown mechanism to limit transient overvoltages before they damage downstream ICs or MOSFETs. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<1 µA at VWM), while the 10/1000 µs surge response enables effective suppression of inductive switching spikes and ESD events.
Designed for surface-mount assembly on standard 0.2" × 0.2" copper pads per terminal, it delivers 600 W peak pulse power with 0.01% duty cycle repeatability and meets J-STD-020 MSL Level 1 (260 °C reflow peak). Its unidirectional configuration supports DC-biased rails where reverse conduction must be blocked.
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 bias margin. |
| VBR (Breakdown) | 77.9–86.1 V at 1 mA - 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 surge; determines stress on downstream components. |
| PPPM | 600 W - Surge energy handling capacity; sufficient for automotive load-dump and industrial inductive kickback. |
| IPPM | 5.3 A - Peak pulse current capability at rated clamping voltage; correlates directly with system-level surge immunity. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard PCB; informs derating above 25 °C ambient. |
| TJ max | +150 °C - Maximum junction temperature; supports operation in under-hood automotive and high-temp industrial environments. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode identified by black band; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when VLINE exceeds VBR. |
| Anode (unbanded end) | Reference node | Typically tied to ground or low-impedance return path; completes clamping loop during overvoltage event. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables single-device protection against ISO 7637-2 Pulse 5a (load dump) in 12 V automotive systems. |
| Low incremental surge resistance | Minimizes VC overshoot during fast transients, improving protection margin for 3.3 V/5 V logic interfaces. |
| Glass passivated junction | Ensures long-term stability of VBR and leakage performance across temperature and lifetime stress. |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow without preconditioning or special handling requirements. |
| AEC-Q101 qualification path | HE3/HM3 variants available for automotive applications requiring qualified TVS devices (e.g., body control modules). |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Module |
|---|---|

Use Value: Suppresses sub-100 ns ringing and cross-talk spikes that exceed IC absolute maximum ratings but fall below primary OVP thresholds. |
Use Scenario: Safeguards high-side and low-side gate drivers in half-bridge inverters from shoot-through-induced voltage spikes during MOSFET switching. IC Role / Device Role / Timing Role: Localized clamping device placed at driver IC supply pins to clamp VDD-to-ground transients.

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 (Microchip) | Same SMB package, 85 V VBR min (80.8–89.2 V), 118 V VC at 5.1 A; slightly higher clamping voltage and lower IPPM. | Marginally reduced surge margin in 12 V automotive systems due to +5 V higher VC; acceptable for non-critical I/O protection. | Select when sourcing diversification is required and 118 V clamping is acceptable for protected IC VDS/VIN rating. |
| 1.5SMC82A (ON Semiconductor) | SAME VWM/VBR/VC specs, identical 600 W rating, but in larger SMC (DO-214AB) package; 1.5× footprint area and higher RθJA (85 °C/W). | Requires PCB layout change; better suited for high-power industrial boards where thermal mass compensates for larger size. | Choose only if existing design uses SMC footprint or requires enhanced thermal dissipation via larger copper area. |
Compared with SMAJ85A and 1.5SMC82A, the P6SMB82A-E3/52 offers optimal balance of compact SMB packaging, precise 70.1 V standoff, and industry-leading 113 V clamping - making it preferred for space-constrained automotive and industrial control designs where layout efficiency and voltage margin are critical.

FAQ
What is the standoff voltage (VWM) of the P6SMB82A-E3/52?
The P6SMB82A-E3/52 has a maximum reverse standoff voltage (VWM) of 70.1 V at 25 °C. This value represents the highest continuous DC or RMS voltage the device can block without entering breakdown - critical for ensuring no leakage or false triggering during normal operation of a 60 V nominal system. The P6SMB82A-E3/52 maintains this rating across its specified temperature range with minimal drift.
Is the P6SMB82A-E3/52 RoHS-compliant and halogen-free?
Yes, the P6SMB82A-E3/52 carries the "E3" suffix, indicating it is RoHS-compliant and manufactured to Vishay's commercial-grade specifications. It is not halogen-free; for halogen-free compliance, the "M3" variant (e.g., P6SMB82A-M3/52) must be selected. Both E3 and M3 meet JESD 201 Class 2 whisker resistance and J-STD-002 solderability standards.
Does the P6SMB82A-E3/52 have AEC-Q101 qualification?
The base P6SMB82A-E3/52 is not AEC-Q101 qualified; however, Vishay offers automotive-grade versions under ordering codes P6SMB82AHE3_B and P6SMB82AHM3_B (with "_B" revision code), which are fully AEC-Q101 qualified for use in automotive applications such as body control modules and infotainment power supplies. The P6SMB82A-E3/52 itself is commercial-grade.
What is the clamping voltage (VC) of the P6SMB82A-E3/52 at its rated peak pulse current?
The P6SMB82A-E3/52 exhibits a maximum clamping voltage (VC) of 113 V when subjected to its rated 10/1000 µs peak pulse current of 5.3 A. This value is measured under standardized test conditions (TA = 25 °C, mounted on 0.2" × 0.2" copper pads) and defines the upper voltage limit imposed on protected circuitry during surge events - a key parameter for verifying compatibility with downstream IC absolute maximum ratings.
Can the P6SMB82A-E3/52 be used in bidirectional configurations?
No, the P6SMB82A-E3/52 is a unidirectional TVS diode, indicated by the "A" suffix (as opposed to "CA" for bidirectional types like P6SMB82CA). Its cathode band marks the polarity-sensitive terminal, and it conducts only during positive overvoltage relative to its anode. For AC or dual-polarity signal line protection, a bidirectional variant must be selected - the P6SMB82A-E3/52 is unsuitable for such applications.
