Product details
Overview
P6SMB82AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 600 W peak pulse power (10/1000 μs), 70.1 V stand-off voltage (VWM), and 113 V maximum clamping voltage (VC) at 5.3 A peak pulse current. It protects MOSFETs and ICs in automotive power supplies against inductive switching transients.
For engineers reviewing the P6SMB82AHE3_B/H datasheet, P6SMB82AHE3_B/H pinout, P6SMB82AHE3_B/H application, or P6SMB82AHE3_B/H equivalent, key selection criteria include clamping voltage margin relative to protected device VDS/VCC, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and unidirectional polarity with cathode band marking.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (<1 μA leakage at 70.1 V), but triggers avalanche conduction when transient voltage exceeds its 77.9–86.1 V breakdown range (IT = 1 mA). Its glass-passivated junction ensures stable breakdown and low incremental surge resistance.
Designed for automated SMT assembly on PCBs with 5.0 mm × 5.0 mm copper pads per terminal, it meets J-STD-020 MSL Level 1 (peak reflow 260 °C) and supports repetitive 0.01% duty-cycle surges. The HE3 suffix confirms RoHS compliance and AEC-Q101 qualification for automotive use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 70.1 V - Maximum continuous reverse operating voltage before leakage exceeds 1 μA; sets upper limit for protected circuit DC rail. |
| VBR min/max | 77.9 V / 86.1 V at 1 mA - Confirmed avalanche onset range; ensures reliable triggering above system nominal voltage. |
| VC @ IPPM | 113 V at 5.3 A - Clamped voltage during 10/1000 μs surge; must stay below protected device absolute maximum rating. |
| PPPM | 600 W - Peak pulse power handling capability; defines transient energy absorption capacity per event. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard pad layout; determines steady-state power derating above 25 °C. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, matte tin-plated leads, 5.59 mm × 4.06 mm × 2.20 mm body, cathode indicated by band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or low-voltage return path; completes shunt path during transient conduction. |
| Cathode | High-side protection node | Connected to protected line (e.g., 48 V rail); avalanche conduction initiates here when voltage exceeds VBR. |
Key Features
| Feature | Design Value |

| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without pre-baking or special handling. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., load dump), improving clamping precision. |
Applications
| Automotive Power Supply Protection | Industrial Motor Drive I/O Protection |
|---|---|

Use Scenario: Safeguarding microcontroller I/O pins and display backlight drivers against user-handling ESD in smart home hubs. IC Role / Device Role / Timing Role: Board-level TVS on USB, UART, and LED driver lines, leveraging fast response time (<1 ns) to divert ESD currents. Use Value: Delivers 30 kV air-gap ESD protection (IEC 61000-4-2 level 4) without requiring additional series impedance or filtering. |
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-E3/52 | Same SMB package, 85 V VBR min (80.8–89.2 V), 118 V VC @ 5.1 A, non-AEC-Q101 commercial grade. | Lacks automotive qualification; suitable for industrial/commercial designs where AEC-Q101 is not mandated. | Select when cost sensitivity outweighs automotive reliability requirements and clamping margin allows 118 V. |
| 1.5SMC82A | Same VWM/VBR/VC specs, but in larger SMC (DO-214AB) package (7.11 mm × 6.22 mm), RθJA = 40 °C/W. | Better thermal performance but requires larger PCB area; incompatible with dense automotive layouts. | Choose only if board space permits and thermal derating demands lower RθJA than SMB can provide. |
Compared with SMAJ85A-E3/52, P6SMB82AHE3_B/H offers AEC-Q101 validation critical for automotive deployment; versus 1.5SMC82A, it delivers identical electrical protection in 30% smaller footprint but requires tighter thermal management due to higher RθJA.

FAQ
What is the breakdown voltage range for P6SMB82AHE3_B/H?
The P6SMB82AHE3_B/H has a guaranteed breakdown voltage (VBR) range of 77.9 V to 86.1 V at 1 mA test current, measured per ANSI/IEEE C62.35. This range ensures reliable triggering above typical 48 V automotive system voltages while maintaining margin below protected device limits. The P6SMB82AHE3_B/H's specified VBR tolerance supports robust design against manufacturing variation and temperature drift.
Is P6SMB82AHE3_B/H suitable for automotive applications?
Yes, P6SMB82AHE3_B/H is AEC-Q101 qualified, with full stress testing including temperature cycling, high-temperature reverse bias, and ESD per automotive reliability standards. Its HE3 suffix explicitly denotes RoHS-compliant and AEC-Q101-qualified construction. The P6SMB82AHE3_B/H is validated for under-hood and cabin applications such as battery management, ADAS sensor interfaces, and infotainment power rails.
What is the maximum clamping voltage of P6SMB82AHE3_B/H during a surge?
The P6SMB82AHE3_B/H clamps to a maximum of 113 V at 5.3 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is guaranteed across temperature and lifetime, and defines the upper voltage seen by downstream components during transient events. Designers must ensure this clamping voltage remains below the absolute maximum ratings of protected ICs or MOSFETs in the P6SMB82AHE3_B/H-protected circuit.
Does P6SMB82AHE3_B/H have polarity markings?
Yes, P6SMB82AHE3_B/H is unidirectional and features a visible cathode band on the SMB package body. The banded end connects to the higher-potential side (e.g., 48 V rail), while the unbanded end connects to ground. This polarity must be observed during placement; reverse orientation prevents proper clamping and may cause catastrophic failure. No marking is used on bidirectional variants, but P6SMB82AHE3_B/H is strictly unidirectional.
What is the thermal resistance of P6SMB82AHE3_B/H?
The P6SMB82AHE3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value governs steady-state power dissipation derating: at 50 °C ambient, its 5.0 W rated power drops to ~3.3 W. For high-power or high-temperature environments, thermal relief traces or additional copper pour should be used to improve heat spreading beyond the baseline layout.
