Product details
Overview
P6SMB82CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal or power 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 (IPPM), and 600 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the P6SMB82CAHE3_A/H datasheet, P6SMB82CAHE3_A/H pinout, P6SMB82CAHE3_A/H application, or P6SMB82CAHE3_A/H equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification status, SMB (DO-214AA) package thermal performance, and compliance with IEC 61000-4-2/4-4/4-5 surge immunity requirements.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, delivering identical clamping behavior above ±70.1 V standoff. Its glass-passivated junction enables fast response (<1 ns) to ESD and lightning-induced transients while maintaining low incremental surge resistance (ΔVC/ΔIPPM ≈ 21.3 Ω).
Designed for surface-mount assembly on 5.0 mm × 5.0 mm copper pads per terminal, it achieves 100 °C/W junction-to-ambient thermal resistance and supports repetitive surge duty cycles up to 0.01 % - validated under AEC-Q101 stress conditions including temperature cycling, HTRB, and ESD-HBM ≥ 8 kV.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ82CA | Same VWM (70.1 V), VC (113 V), and SMB package; rated for 600 W but not AEC-Q101 qualified | Lacks automotive qualification; suitable for commercial/industrial use only | Select when AEC-Q101 is not required and cost optimization is prioritized |
| 1.5KE82CA | Through-hole DO-15 package; same electrical specs but higher RθJA (70 °C/W vs. 100 °C/W) and larger footprint | Requires PCB layout change; less suitable for high-density SMT designs | Choose only if legacy through-hole assembly or higher surge margin (1500 W) is needed |
Compared with SMBJ82CA and 1.5KE82CA, P6SMB82CAHE3_A/H uniquely combines AEC-Q101 qualification, SMB footprint, and 600 W surge rating - making it the preferred choice for space-constrained automotive electronics where qualification and reliability are mandatory.

FAQ
What is the clamping voltage of P6SMB82CAHE3_A/H at its rated peak pulse current?
The P6SMB82CAHE3_A/H has a maximum clamping voltage (VC) of 113 V at 5.3 A peak pulse current (IPPM), measured under the standardized 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is confirmed in the Vishay datasheet revision 09-Jan-2024, page 2, Electrical Characteristics table.
Is P6SMB82CAHE3_A/H qualified for automotive applications?
Yes, P6SMB82CAHE3_A/H is AEC-Q101 qualified, as indicated by the "HE3" suffix and documented in the Vishay P6SMB datasheet section "Mechanical Data" and "Ordering Information". This qualification covers temperature cycling, high-temperature reverse bias, and ESD testing - confirming suitability for under-hood and ADAS-related deployments.
What does the "CA" suffix mean in P6SMB82CAHE3_A/H?
The "CA" suffix in P6SMB82CAHE3_A/H denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression in both polarities. Unlike unidirectional variants (e.g., P6SMB82A), this part has no cathode marking and functions identically whether voltage stress is applied in positive or negative direction relative to ground.
What is the standoff voltage (VWM) specification for P6SMB82CAHE3_A/H?
The standoff voltage (VWM) for P6SMB82CAHE3_A/H is 70.1 V - the maximum DC or continuous peak reverse voltage the device can withstand without entering avalanche conduction. This parameter ensures reliable operation in 48 V automotive systems and 24 V industrial buses where normal operating voltages remain safely below clamping onset.
Does P6SMB82CAHE3_A/H meet RoHS and halogen-free requirements?
P6SMB82CAHE3_A/H is RoHS-compliant (per EU Directive 2011/65/EU) and carries the "HE3" suffix, indicating RoHS compliance and AEC-Q101 qualification. It is not halogen-free; for halogen-free compliance, the "HM3" variant (e.g., P6SMB82CAHM3_A/H) must be selected instead.
