Product details
Overview
P6SMB82AHE3_B/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 sensitive electronics. It features a 70.1 V stand-off voltage (VWM), 77.9–86.1 V breakdown voltage (VBR) at 1 mA test current, and clamps transients to ≤113 V at 5.3 A peak pulse current (IPPM) under 10/1000 µs waveform - deployed on power rails and signal lines in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the P6SMB82AHE3_B/I datasheet, P6SMB82AHE3_B/I pinout, P6SMB82AHE3_B/I application, or P6SMB82AHE3_B/I equivalent, key selection criteria include its AEC-Q101 qualification, 600 W peak pulse power rating, low 100 °C/W junction-to-ambient thermal resistance, SMB (DO-214AA) package compatibility with automated SMT assembly, and unidirectional polarity with cathode band marking.
Technical Context
This TVS diode operates as a clamping device that remains high-impedance below VWM = 70.1 V and rapidly transitions to low-impedance conduction above VBR (min 77.9 V), limiting transient voltages to ≤113 V at rated IPPM. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response time (<1.0 ns), critical for protecting MOSFET gates and microcontroller I/O pins.
The device is rated for 100 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), supports continuous power dissipation of 5.0 W at 50 °C ambient, and maintains operation across –65 °C to +150 °C junction temperature range - validated per JESD22-B102 solderability and J-STD-020 MSL Level 1 (260 °C peak reflow).
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 rail margin. |
| VBR (Breakdown) | 77.9–86.1 V at 1 mA - Confirmed avalanche onset range; ensures reliable triggering without premature conduction. |
| VC (Clamping) | ≤113 V at 5.3 A (10/1000 µs) - Actual worst-case transient suppression level; determines protected circuit's voltage stress ceiling. |
| PPPM | 600 W - Peak pulse power handling capacity; enables survival of high-energy ESD and load-dump events. |
| IPPM | 5.3 A - Peak pulse current supported at VC; directly correlates with system-level surge immunity (e.g., ISO 7637-2 Pulse 5a). |
| TJ max | +150 °C - Maximum junction temperature; allows operation in under-hood automotive environments and sealed industrial enclosures. |
| RθJA | 100 °C/W - Thermal resistance junction-to-ambient; informs derating requirements on standard 0.2" × 0.2" copper pads. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads compliant with J-STD-002 and JESD22-B102. Cathode indicated by molded band; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line (e.g., VCC or signal); conducts surge current to ground during overvoltage event. |
| Anode (unmarked end) | Reference node | Typically tied to system ground or lower-potential rail; completes clamping path and defines unidirectional polarity. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, ADAS sensors, and infotainment power rails. |
| 600 W peak pulse power (10/1000 µs) | Withstands ISO 7637-2 load-dump surges up to 120 V/300 ms and IEC 61000-4-5 combination wave (40 Ω source) events. |
| Glass passivated junction | Ensures stable VBR tolerance (±5 %), low leakage (<1 µA), and long-term reliability under thermal cycling. |
| MSL Level 1 (260 °C) | Compatible with standard lead-free reflow profiles without preconditioning; eliminates moisture-related popcorning risk. |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., ESD >15 kV contact discharge). |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Clamping |

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-E3/5B | Higher VWM = 72.2 V, VBR = 85–94.4 V, VC = 129 V at 4.7 A; same SMB package but lower PPPM (400 W). | Limited to lower-energy surges; unsuitable for automotive load-dump where 600 W is required. | Select only if system-level testing confirms 400 W suffices and higher clamping voltage (129 V vs. 113 V) is acceptable. |
| 1.5SMC82A | Same VWM/VBR/VC specs, but SMC (DO-214AB) package - 2.5 mm wider, incompatible with SMB footprints. | Requires PCB redesign; not suitable for space-constrained automotive modules using SMB layout. | Choose only when board real estate permits larger SMC footprint and AEC-Q101 qualification is not mandatory. |
Compared with SMAJ85A-E3/5B and 1.5SMC82A, P6SMB82AHE3_B/I uniquely combines AEC-Q101 qualification, 600 W pulse rating, SMB footprint compatibility, and 113 V clamping - making it the only option meeting full ISO 16750-2 load-dump and IEC 61000-4-5 Level 4 requirements in compact automotive and industrial designs.

FAQ
What is the clamping voltage of the P6SMB82AHE3_B/I under a 10/1000 µs surge?
The P6SMB82AHE3_B/I clamps to a maximum of 113 V when subjected to its rated peak pulse current of 5.3 A under the standardized 10/1000 µs waveform. This value is measured per JEDEC standards and reflects worst-case voltage seen by downstream circuitry during surge events - critical for validating protection margins in 12 V automotive systems and industrial 24 V rails. The P6SMB82AHE3_B/I achieves this with low incremental resistance, minimizing overshoot beyond the specified VC.
Is the P6SMB82AHE3_B/I qualified for automotive use?
Yes, the P6SMB82AHE3_B/I is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3_B", where "_B" denotes AEC-Q101 qualification for the P6SMB6.8A to P6SMB220A family. This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - making the P6SMB82AHE3_B/I suitable for under-hood and chassis-mounted automotive electronics such as body control modules and ADAS sensor power supplies.
What does the "HE3_B/I" suffix mean in P6SMB82AHE3_B/I?
In P6SMB82AHE3_B/I, "HE3" indicates RoHS-compliant construction with AEC-Q101 qualification, "_B" specifies AEC-Q101 qualification level for the 6.8 V–220 V unidirectional/bidirectional range, and "/I" denotes packaging in 13-inch diameter tape-and-reel format with 3200 units per reel. This full suffix confirms the part meets automotive reliability standards and ships in high-volume SMT-ready packaging - distinct from commercial-grade "E3" or halogen-free "HM3" variants.
How does the P6SMB82AHE3_B/I compare to bidirectional TVS diodes like P6SMB82CA?
The P6SMB82AHE3_B/I is unidirectional and features a cathode band for polarity-sensitive placement, whereas P6SMB82CA is bidirectional with no polarity marking and symmetric clamping in both directions. The P6SMB82AHE3_B/I offers tighter VBR tolerance (77.9–86.1 V) and lower leakage (<1.0 µA) versus the bidirectional version's higher ID spec. Use P6SMB82AHE3_B/I on DC rails where polarity is fixed (e.g., +12 V to ground); choose P6SMB82CA only for AC-coupled or floating signal lines requiring symmetrical protection.
What is the maximum continuous power dissipation for the P6SMB82AHE3_B/I?
The P6SMB82AHE3_B/I has a maximum continuous power dissipation (PD) of 5.0 W when mounted on an infinite heatsink at TA = 50 °C. In typical PCB layouts with 0.2" × 0.2" copper pads per terminal, derating applies per Figure 2 in the datasheet - e.g., ~3.5 W at 70 °C ambient. This rating governs steady-state thermal management during sustained overvoltage conditions or high-duty-cycle transients, and must be verified alongside RθJA = 100 °C/W in actual layout simulations. The P6SMB82AHE3_B/I's thermal design supports long-term reliability in sealed enclosures.
