Product details
Overview
P6SMB82AHE3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping voltage transients on 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 capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P6SMB82AHE3/5B datasheet, P6SMB82AHE3/5B pinout, P6SMB82AHE3/5B application, or P6SMB82AHE3/5B equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and compliance with J-STD-020 MSL Level 1 handling requirements.
Technical Context
This TVS diode operates as a clamping device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold, limiting transient energy to downstream circuitry. Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns), while the low incremental surge resistance supports robust clamping under repetitive 10/1000 μs surges at 0.01% duty cycle.
The P6SMB82AHE3/5B is rated for -65 °C to +150 °C operating junction temperature and delivers 5.0 W steady-state power dissipation on an infinite heatsink at 50 °C ambient. Its matte tin-plated leads meet J-STD-002 solderability standards and JESD22-B102 whisker testing (Class 2).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 70.1 V - Maximum continuous reverse working voltage before significant leakage; defines safe operating margin below clamping onset. |
| VBR (Breakdown) | 77.9–86.1 V at 1 mA - Measured voltage range where avalanche conduction begins; determines minimum overvoltage trigger point. |
| VC (Clamping) | 113 V at IPPM = 5.3 A - Peak voltage seen across device during 10/1000 μs transient; directly limits stress on protected IC or MOSFET. |
| PPPM | 600 W - Peak pulse power handling with 10/1000 μs waveform; quantifies transient energy absorption capacity per event. |
| ID (Leakage) | 1.0 μA max at VWM - Reverse leakage current level; critical for low-power sensor or battery-backed circuits where quiescent drain matters. |
| TJ max | +150 °C - Maximum junction temperature; sets thermal design boundary for PCB copper pad sizing and airflow requirements. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance; used to calculate temperature rise under DC or repetitive pulse conditions. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads. Cathode indicated by band marking; unidirectional polarity confirmed per ordering code suffix "A".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / reverse voltage reference | Connected to lower-potential side of protected line; defines directionality of clamping action. |
| Cathode | Avalanche conduction terminal / clamping node | Banded end; connected to higher-potential rail (e.g., VBUS or signal line); conducts transient current to ground path. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD; suitable for under-hood and ADAS sensor protection. |
| Glass passivated junction | Ensures stable VBR tolerance and low leakage drift over time and temperature; improves long-term clamping consistency. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without preconditioning; eliminates moisture-related popcorning risk. |
| 600 W 10/1000 μs rating | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-earth) when properly laid out with low-inductance grounding. |
| Low profile SMB footprint | Enables high-density placement near connectors or IC inputs; reduces parasitic inductance versus larger DO-214AB packages. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ82A-E3/5B | Same VWM (70.1 V), VC (113 V), and PPPM (600 W), but in smaller SMA (DO-214AC) package with RθJA = 140 °C/W. | Limited thermal margin in high-ambient or high-duty-cycle environments; not AEC-Q101 qualified. | Select when board space is constrained and automotive qualification is unnecessary. |
| 1.5SMC82AHE3/A | Same electrical specs but in larger SMC (DO-214AB) package with higher thermal mass (RθJA = 60 °C/W) and 1.5 kW PPPM rating. | Over-specified for 600 W needs; requires larger PCB area and may increase layout inductance. | Choose only if system-level surge testing exceeds IEC 61000-4-5 Level 4 or long-term thermal derating is critical. |
Compared with SMAJ82A-E3/5B, the P6SMB82AHE3/5B offers superior thermal performance and automotive qualification; compared with 1.5SMC82AHE3/A, it provides optimal balance of surge capability, footprint size, and AEC-Q101 compliance for space-constrained automotive and industrial designs.

FAQ
What is the clamping voltage of the P6SMB82AHE3/5B under a 10/1000 μs surge?
The P6SMB82AHE3/5B 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 per Figure 1 in the Vishay datasheet 88370 and defines the upper voltage limit imposed on protected circuitry during standardized surge events. The P6SMB82AHE3/5B maintains this clamping performance across its full operating temperature range (-65 °C to +150 °C) when mounted per recommended pad layout.
Is the P6SMB82AHE3/5B AEC-Q101 qualified?
Yes, the P6SMB82AHE3/5B is AEC-Q101 qualified, as confirmed by the "HE3" suffix and documentation in Vishay's P6SMB series datasheet (Rev. 09-Jan-2024, Doc. #88370). The "_B" revision suffix further indicates AEC-Q101 qualification for models ranging from P6SMB6.8A to P6SMB220A. This qualification covers stress tests including temperature cycling, highly accelerated life testing (HALT), and ESD, making the P6SMB82AHE3/5B suitable for automotive powertrain and body electronics.
What does the "5B" in P6SMB82AHE3/5B signify?
The "5B" in P6SMB82AHE3/5B denotes the packaging configuration: 13-inch diameter plastic tape and reel, with 3200 units per reel. This differs from "52", which indicates a 7-inch reel containing 750 units. Both configurations use the same SMB (DO-214AA) package and identical electrical specifications. The P6SMB82AHE3/5B is RoHS-compliant and AEC-Q101 qualified, with matte tin-plated leads meeting J-STD-002 solderability standards.
How does the P6SMB82AHE3/5B compare to bidirectional variants like P6SMB82CAHE3/5B?
The P6SMB82AHE3/5B is unidirectional, with cathode marked by a band and intended for DC-biased lines where transients occur only in one polarity. In contrast, P6SMB82CAHE3/5B is bidirectional, lacking polarity marking and capable of clamping both positive and negative transients - suitable for AC lines or differential signals. Their VWM, VBR, and VC values differ: P6SMB82CAHE3/5B has VWM = 70.1 V (same), but VBR = 77.9–86.1 V in both directions and VC = 125 V at 4.8 A. The P6SMB82AHE3/5B is not interchangeable with P6SMB82CAHE3/5B without circuit redesign.
What is the maximum steady-state power dissipation for the P6SMB82AHE3/5B?
The P6SMB82AHE3/5B has a maximum steady-state power dissipation (PD) of 5.0 W when mounted on an infinite heatsink at TA = 50 °C, as specified in the "Maximum Ratings" table of Vishay's datasheet 88370. This rating assumes ideal thermal conduction and is derated linearly above 50 °C ambient. For typical PCB layouts with 0.2" x 0.2" copper pads per terminal, actual usable DC power is limited to ~1.2 W at 70 °C ambient due to RθJA = 100 °C/W. The P6SMB82AHE3/5B is not intended for continuous power dissipation but for transient suppression only.
