Product details
Overview
P6SMB82CAHM3_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 82 V breakdown voltage (VBR min/max = 77.9 V / 86.1 V at 1 mA), 70.1 V standoff voltage (VWM), and clamps to ≤113 V at 5.3 A peak pulse current (IPPM) under 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the P6SMB82CAHM3_A/H datasheet, P6SMB82CAHM3_A/H pinout, P6SMB82CAHM3_A/H application, or P6SMB82CAHM3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, SMB (DO-214AA) package compatibility, and 600 W peak pulse power handling with low incremental surge resistance.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling suppression of positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the low thermal resistance (RθJL = 20 °C/W) supports reliable energy dissipation during repetitive surges.
The device complies with J-STD-020 MSL Level 1 (peak reflow = 260 °C) and is halogen-free, RoHS-compliant, and AEC-Q101 qualified - confirming suitability for automotive-grade PCB assembly. Its 100 °C/W junction-to-ambient thermal resistance (RθJA) assumes standard 0.2" × 0.2" copper pads per terminal, defining layout-dependent derating above 25 °C ambient.

Use Scenario: Safeguarding 4–20 mA current loop inputs in programmable logic controllers against field-wiring induced surges and lightning-induced coupling. IC Role / Device Role / Timing Role: Parallel-connected TVS shunting transient energy away from precision op-amps and ADC front-ends during 1 kV/500 A surge events. Use Value: Maintains measurement accuracy by limiting input voltage excursion to ≤113 V, avoiding saturation or damage to 24 V-rated signal conditioning circuitry. |
| Telecom Line Card Protection | Consumer Appliance Motor Control |
|

IC Role / Device Role / Timing Role: TVS mounted at motor connector to absorb inductive kickback spikes generated during PWM commutation. Use Value: Extends MCU lifetime by limiting voltage stress to ≤113 V during 100 A inrush events, preventing I/O port latch-up or reset corruption. |
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/VBR/VC, but not AEC-Q101 qualified; rated for 600 W, 10/1000 µs | Targeted at commercial/industrial systems where automotive qualification is not required | Select when cost sensitivity outweighs automotive reliability validation needs |
| 1.5KE82CA | Through-hole DO-201 package; same electrical specs but higher RθJA (75 °C/W vs. 100 °C/W); 1.5 kW rating | Suitable for prototyping or legacy through-hole designs; less suitable for high-density SMT layouts | Choose only if board design mandates axial/DO-201 footprint or requires higher single-pulse energy margin |
Compared with SMBJ82CA and 1.5KE82CA, P6SMB82CAHM3_A/H uniquely combines AEC-Q101 qualification, halogen-free construction, and SMB footprint - making it the preferred choice for production automotive modules requiring zero-layout change and full compliance traceability.

FAQ
What is the clamping voltage of P6SMB82CAHM3_A/H at its rated peak pulse current?
The P6SMB82CAHM3_A/H clamps to a maximum of 113 V when subjected to its specified peak pulse current of 5.3 A under the standard 10/1000 µs waveform. This value is measured at the device terminals and represents the upper limit of voltage imposed on protected circuitry during transient events - critical for ensuring downstream ICs remain within their absolute maximum ratings. The clamping occurs rapidly, typically within <1 ns of transient onset.
Is P6SMB82CAHM3_A/H suitable for automotive applications?
Yes, P6SMB82CAHM3_A/H is AEC-Q101 qualified and manufactured with halogen-free, RoHS-compliant materials - explicitly intended for automotive use cases including engine control units, body electronics, and ADAS sensor interfaces. Its qualification covers temperature cycling, mechanical shock, and humidity testing per AEC standards, and the HM3 suffix confirms automotive-grade traceability and process control.
What does the "CA" suffix indicate in P6SMB82CAHM3_A/H?
The "CA" suffix in P6SMB82CAHM3_A/H denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., P6SMB82A), this version has no cathode band marking and functions identically regardless of terminal orientation, simplifying layout for AC-coupled or floating signal paths.
What is the thermal resistance of P6SMB82CAHM3_A/H from junction to lead?
The P6SMB82CAHM3_A/H has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, measured under standard test conditions. This low value enables efficient heat transfer from the silicon die to the PCB copper pads via the SMB package leads, supporting reliable operation during repetitive surge events - especially important in automotive applications where ambient temperatures may exceed 105 °C.
How does the SMB package of P6SMB82CAHM3_A/H compare to SMA or SMC in terms of power handling?
The SMB (DO-214AA) package used by P6SMB82CAHM3_A/H delivers 600 W peak pulse power - less than SMC's ~1500 W but more than SMA's ~400 W. Its 5.59 mm × 4.06 mm footprint offers a balance between board space efficiency and thermal performance, making it ideal for dense automotive PCBs where SMC would be oversized and SMA insufficient for demanding transients. Mounting on 0.2" × 0.2" copper pads is required to achieve rated performance.
