Product details
Overview
P6SMB82CAHE3_A/I 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 and power 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 and automotive electronics.
For engineers reviewing the P6SMB82CAHE3_A/I datasheet, P6SMB82CAHE3_A/I pinout, P6SMB82CAHE3_A/I application, or P6SMB82CAHE3_A/I equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification status, SMB (DO-214AA) package compatibility, thermal resistance (RθJA = 100 °C/W), and compliance with IEC 61000-4-2/4-4/4-5 surge immunity standards.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, delivering identical clamping performance regardless of transient polarity - critical for protecting AC-coupled or differential signal paths. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while the low incremental surge resistance enables rapid energy absorption without thermal runaway.
The device is rated for repetitive 10/1000 μs surges at 0.01 % duty cycle and supports operating junction temperatures from –65 °C to +150 °C. Its MSL Level 1 rating (per J-STD-020) and matte tin-plated leads ensure robust manufacturability in lead-free reflow processes up to 260 °C peak.
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 |
|---|---|---|---|
| SMAJ85CA | Higher VWM (72.2 V), higher VC (125 V at 4.8 A), same SMB package and 600 W rating | Less margin between VWM (72.2 V) and system nominal voltage - risk of premature conduction in 72 V industrial rails | Select when tighter VBR tolerance (±5 %) is required and 125 V clamping is acceptable for downstream 130 V-rated components. |
| 1.5SMC82CA | Same VWM/VC specs but in larger SMC (DO-214AB) package; RθJA = 60 °C/W vs. 100 °C/W | Requires more PCB area; better thermal performance allows higher sustained surge repetition rates | Choose for high-duty-cycle surge environments (e.g., motor drive feedback loops) where thermal management outweighs space constraints. |
Compared with SMAJ85CA and 1.5SMC82CA, P6SMB82CAHE3_A/I offers optimal balance of compact SMB footprint, AEC-Q101 qualification, and precise 70.1 V stand-off - making it preferred for space-constrained automotive and industrial designs requiring certified reliability.

FAQ
What does the "CA" suffix indicate in P6SMB82CAHE3_A/I?
The "CA" suffix denotes a bidirectional configuration - meaning P6SMB82CAHE3_A/I provides symmetrical transient suppression in both polarities, with identical breakdown and clamping characteristics regardless of voltage polarity. This eliminates polarity orientation concerns during PCB placement and simplifies protection of AC-coupled or differential signal paths.
Is P6SMB82CAHE3_A/I qualified for automotive use?
Yes, P6SMB82CAHE3_A/I is AEC-Q101 qualified, as confirmed by its HE3 suffix and documentation in Vishay's P6SMB datasheet (Rev. 09-Jan-2024). This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and ESD, validating its suitability for under-hood and cabin electronics such as body control modules and sensor interfaces.
How does the SMB (DO-214AA) package of P6SMB82CAHE3_A/I compare thermally to larger packages?
P6SMB82CAHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. While larger packages like SMC offer lower RθJA (~60 °C/W), the SMB footprint enables high-density layouts - and P6SMB82CAHE3_A/I's 600 W rating remains fully achievable within its specified derating curve up to +150 °C junction temperature.
What is the maximum clamping voltage of P6SMB82CAHE3_A/I under standard test conditions?
The maximum clamping voltage (VC) of P6SMB82CAHE3_A/I is 113 V, measured at 5.3 A peak pulse current (IPPM) using the industry-standard 10/1000 μs double-exponential waveform. This value represents the highest voltage imposed on protected circuitry during worst-case transient events, and is guaranteed across the full operating temperature range.
Does P6SMB82CAHE3_A/I require polarity-aware PCB layout?
No - P6SMB82CAHE3_A/I is a bidirectional TVS with no cathode marking and electrically symmetric terminals. Unlike unidirectional variants (e.g., P6SMB82A), it imposes no polarity constraints during placement, enabling simplified routing for differential signals, AC power lines, or any application where transient direction is unpredictable.
