Product details
Overview
P6SMB82CAHE3_B/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, and 600 W peak pulse power capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6SMB82CAHE3_B/H datasheet, P6SMB82CAHE3_B/H pinout, P6SMB82CAHE3_B/H application, or P6SMB82CAHE3_B/H equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification for automotive use, SMB (DO-214AA) package compatibility with automated SMT placement, and thermal resistance (RθJA = 100 °C/W) under standard PCB pad layout.
Technical Context
This device operates as a voltage-clamping protector with symmetrical reverse/forward conduction behavior due to its bidirectional construction. Its glass-passivated junction ensures stable avalanche characteristics and low incremental surge resistance, enabling fast response (<1 ns) to ESD and lightning-induced transients.
The P6SMB82CAHE3_B/H is rated for repetitive 10/1000 μs pulses at 0.01% duty cycle and supports continuous power dissipation of 5.0 W at 50 °C ambient on an infinite heatsink. Junction temperature range spans −65 °C to +150 °C, and it meets MSL Level 1 per J-STD-020 with peak reflow temperature up to 260 °C.

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 SMB package, identical VWM/VC, but not AEC-Q101 qualified; lower surge rating (600 W vs. same) | Commercial-grade only; unsuitable for automotive production without additional qualification | Select when AEC-Q101 is not required and cost sensitivity outweighs automotive compliance needs |
| 1.5SMC82CA | Larger SMC (DO-214AB) package; same electrical specs but higher RθJA (70 °C/W); 1.5 kW peak power rating | Used where higher single-pulse energy handling is needed, but board space and thermal layout differ significantly | Choose for legacy designs using SMC footprints or applications demanding >600 W single-event margin |
Compared with SMBJ82CA and 1.5SMC82CA, the P6SMB82CAHE3_B/H uniquely combines AEC-Q101 qualification, SMB footprint, and precise 600 W/113 V clamping performance - making it optimal for space-constrained automotive and industrial modules requiring certified reliability without package redesign.

FAQ
What does the "CA" suffix indicate in P6SMB82CAHE3_B/H?
The "CA" suffix denotes a bidirectional configuration, meaning the P6SMB82CAHE3_B/H provides symmetrical clamping in both forward and reverse directions - essential for protecting AC-coupled signals, differential buses like RS-485, or floating sensor inputs where polarity is undefined. Unlike unidirectional variants (e.g., P6SMB82A), it has no cathode marking and identical VBR and VC in either direction.
Is P6SMB82CAHE3_B/H suitable for automotive applications?
Yes, the P6SMB82CAHE3_B/H is AEC-Q101 qualified (indicated by the "HE3_B" suffix), validating its performance across temperature cycling, humidity, mechanical shock, and surge endurance tests required for automotive electronics. It is commonly deployed in body control modules, ADAS sensor interfaces, and infotainment power rails where certified reliability is mandatory.
What is the maximum clamping voltage of P6SMB82CAHE3_B/H under surge conditions?
The maximum clamping voltage (VC) of P6SMB82CAHE3_B/H is 113 V, measured at 5.3 A peak pulse current (IPPM) using the standardized 10/1000 μs waveform. This value defines the highest voltage imposed on the protected circuit during a transient event and must be compared against the absolute maximum ratings of downstream ICs to ensure safe operation.
How does the SMB (DO-214AA) package of P6SMB82CAHE3_B/H compare to SMC (DO-214AB)?
The SMB package of P6SMB82CAHE3_B/H measures 4.57 mm × 3.94 mm × 2.20 mm - approximately 30% smaller in footprint than the SMC (DO-214AB) package. While both share similar thermal performance under defined pad layouts, the SMB enables higher PCB density and is optimized for fine-pitch automated assembly, whereas SMC offers higher single-pulse energy handling (e.g., 1.5SMC82CA at 1.5 kW).
What is the standoff voltage (VWM) of P6SMB82CAHE3_B/H, and why does it matter?
The standoff voltage (VWM) of P6SMB82CAHE3_B/H is 70.1 V - the maximum continuous reverse voltage the device can block without entering avalanche conduction. This parameter ensures the P6SMB82CAHE3_B/H remains non-conductive during normal operation, minimizing leakage current and avoiding false triggering, while still providing sufficient margin below its 77.9–86.1 V breakdown range for reliable transient response.
