Product details
Overview
P6SMB82AHE3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, 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 test current, 113 V maximum clamping voltage (VC) at 5.3 A peak pulse current (IPPM), 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 P6SMB82AHE3/52 datasheet, P6SMB82AHE3/52 pinout, P6SMB82AHE3/52 application, or P6SMB82AHE3/52 equivalent, key selection criteria include unidirectional polarity, SMB (DO-214AA) package compatibility, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and clamping performance under repetitive surge conditions.
Technical Context
This TVS diode operates as a voltage-clamping protection device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable leakage behavior and fast response time (<1 ns), while low incremental surge resistance minimizes voltage overshoot during transient events.
The device is rated for 150 °C maximum junction temperature and meets J-STD-020 MSL Level 1 moisture sensitivity with 260 °C lead-free reflow peak. It is RoHS-compliant and AEC-Q101 qualified (indicated by HE3 suffix), supporting automotive-grade reliability in harsh environments without derating up to 125 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 70.1 V - Maximum continuous reverse operating voltage before significant leakage; defines safe operating margin below clamping onset. |
| VBR (Breakdown) | 77.9–86.1 V at 1 mA - Voltage range where avalanche conduction begins; tight tolerance enables precise overvoltage threshold setting. |
| VC (Clamping) | 113 V at 5.3 A IPPM - Peak voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream components. |
| PPPM | 600 W - Peak pulse power handling with standard 10/1000 μs waveform; supports robust protection against IEC 61000-4-5 surges. |
| ID (Leakage) | 1.0 μA max at VWM - Ultra-low reverse leakage preserves signal integrity and battery life in always-on circuits. |
| TJ max | 150 °C - Maximum junction temperature rating; allows operation in high-ambient industrial or under-hood automotive locations. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient; informs PCB copper pad sizing (0.2" × 0.2") for thermal management. |
Pinout & Package

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 | Higher VWM (72.2 V), slightly higher VC (116 V at 5.2 A), same SMB package and 600 W rating. | Marginally looser VBR tolerance (72.2–80.2 V vs. 77.9–86.1 V); less precise clamping threshold. | Select SMAJ85A only if tighter VBR matching is not required and legacy design reuse is prioritized. |
| 1.5SMC82A | Same VWM (70.1 V) and VC (113 V), but larger SMC (DO-214AB) package (7.11 mm × 6.22 mm) and higher RθJA (60 °C/W). | Requires larger PCB area and different thermal pad layout; better suited for higher-power, lower-density designs. | Choose 1.5SMC82A when board space permits and higher thermal mass improves long-term surge endurance. |
Compared with SMAJ85A and 1.5SMC82A, P6SMB82AHE3/52 offers tighter VBR tolerance, AEC-Q101 qualification, and optimized SMB footprint for high-density automotive and industrial layouts - making it preferred where precision clamping and space-constrained reliability are critical.

FAQ
What is the maximum clamping voltage of P6SMB82AHE3/52 under standard surge conditions?
The P6SMB82AHE3/52 has a maximum clamping voltage (VC) of 113 V when subjected to a 10/1000 μs waveform at 5.3 A peak pulse current (IPPM). This value is measured per JEDEC standards and reflects the highest voltage the protected circuit will experience during a defined transient event. The clamping performance remains stable across its operating temperature range of -65 °C to +150 °C, and the P6SMB82AHE3/52 maintains this specification without degradation under repetitive surge duty cycles up to 0.01%.
Is P6SMB82AHE3/52 qualified for automotive applications?
Yes, P6SMB82AHE3/52 is AEC-Q101 qualified, as confirmed by the "HE3" suffix in its ordering code. This qualification covers stress tests including high-temperature operating life, temperature cycling, and mechanical shock - validating its suitability for under-hood and cabin electronics such as body control modules and ADAS sensor interfaces. The P6SMB82AHE3/52 also meets MSL Level 1 per J-STD-020 and supports lead-free reflow up to 260 °C, aligning with automotive manufacturing requirements.
What package type does P6SMB82AHE3/52 use, and what are its key mechanical dimensions?
P6SMB82AHE3/52 uses the SMB (DO-214AA) surface-mount package, measuring 3.94 mm × 2.20 mm × 2.31 mm (length × width × height) with a cathode band marking. Its standardized footprint features 2.18 mm minimum cathode band spacing and is compatible with automated pick-and-place equipment. The molding compound meets UL 94 V-0 flammability rating, and terminals are matte tin plated for reliable solderability per J-STD-002 - all characteristics documented in Vishay's official P6SMB series datasheet (Document Number: 88370).
How does the breakdown voltage tolerance of P6SMB82AHE3/52 compare to similar TVS diodes?
P6SMB82AHE3/52 exhibits a breakdown voltage (VBR) range of 77.9 V to 86.1 V at 1 mA test current - a ±5.3% tolerance around the nominal 82 V rating. This is tighter than industry-standard alternatives like SMAJ85A (±6.3%) and provides more predictable clamping onset. The P6SMB82AHE3/52 achieves this via controlled avalanche junction processing and is verified per ANSI/IEEE C62.35, ensuring consistent overvoltage response across production lots and temperature extremes.
Can P6SMB82AHE3/52 be used in bidirectional configurations?
No, P6SMB82AHE3/52 is a unidirectional TVS diode, as indicated by the "A" suffix and absence of "CA" in its part number. Its cathode band marking confirms polarity-sensitive placement, and electrical characteristics apply only in reverse-biased mode. For bidirectional protection, Vishay offers the P6SMB82CA variant - which shares identical VWM, VBR, and VC ratings but conducts symmetrically in both directions. Using P6SMB82AHE3/52 in a bidirectional circuit would result in forward conduction and failure during negative transients.
