Product details
Overview
P6SMB82CAHM3_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 stand-off 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 rating with 10/1000 µs waveform - used to protect automotive-grade sensor interfaces and industrial I/O circuits.
For engineers reviewing the P6SMB82CAHM3_B/H datasheet, P6SMB82CAHM3_B/H pinout, P6SMB82CAHM3_B/H application, or P6SMB82CAHM3_B/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, SMB (DO-214AA) package compatibility, and thermal resistance (RθJA = 100 °C/W) for board-level surge protection design.
Technical Context
This device operates as a bidirectional avalanche diode, symmetrically clamping transient overvoltages in both polarities without polarity marking. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1 µA at VWM), while the 10/1000 µs waveform rating reflects standardized lightning/surge immunity testing per IEC 61000-4-5.
The P6SMB82CAHM3_B/H is qualified to AEC-Q101 for automotive applications and uses halogen-free, RoHS-compliant materials (HM3 suffix). Its SMB (DO-214AA) package supports automated placement and meets MSL Level 1 (260 °C reflow peak), with thermal resistance of 20 °C/W junction-to-lead for localized heat dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 70.1 V - Maximum continuous reverse voltage before clamping begins; defines safe operating window for protected circuitry. |
| VBR (Breakdown) | 77.9–86.1 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients. |
| VC (Clamping) | 113 V at 5.3 A - Peak voltage seen by downstream components during 10/1000 µs surge; limits stress on ICs/MOSFETs. |
| PPPM | 600 W - Surge energy handling capacity under standard 10/1000 µs waveform; suitable for IEC 61000-4-5 Level 3/4. |
| IPPM | 5.3 A - Peak pulse current corresponding to VC; determines minimum trace width and PCB copper area required. |
| TJ max. | 150 °C - Maximum junction temperature; enables operation in under-hood automotive environments with derating. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; informs thermal layout requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ85CA | Higher VWM (72.2 V), lower PPPM (400 W), same SMB package | Limited to lower-energy transients; not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification and 600 W surge headroom. |
| 1.5KE82CA | Through-hole DO-15 package, identical VBR/VC, 600 W rating | Requires manual or wave-solder assembly; unsuitable for high-density SMT layouts | Choose only for legacy through-hole designs or prototyping where rework tolerance is prioritized over board space. |
Compared with SMAJ85CA and 1.5KE82CA, the P6SMB82CAHM3_B/H uniquely combines AEC-Q101 qualification, halogen-free construction, and 600 W SMT capability in SMB - making it the preferred choice for production automotive and industrial edge devices requiring zero-layout change upgrades from legacy TVS solutions.

FAQ
What does the "CA" suffix indicate in P6SMB82CAHM3_B/H?
The "CA" suffix denotes a bidirectional configuration - meaning the P6SMB82CAHM3_B/H clamps transient overvoltages equally in both polarities, with no cathode/anode distinction. This is essential for protecting AC-coupled or differential signal lines like RS-485 or CAN, where polarity reversal can occur during surges. The device has symmetrical VBR and VC characteristics in forward and reverse directions.
Is P6SMB82CAHM3_B/H suitable for automotive applications?
Yes, P6SMB82CAHM3_B/H is AEC-Q101 qualified (indicated by the "_B/H" automotive ordering code and HM3 halogen-free RoHS compliance). It is specifically designed for under-hood and chassis-mounted automotive electronics, including body control modules, ADAS sensor interfaces, and infotainment power rails - validated for temperature cycling, humidity, and mechanical shock per AEC-Q101 requirements.
What is the maximum clamping voltage of P6SMB82CAHM3_B/H and how is it measured?
The maximum clamping voltage (VC) of P6SMB82CAHM3_B/H is 113 V, measured at a peak pulse current (IPPM) of 5.3 A using the standardized 10/1000 µs double-exponential waveform per IEC 61000-4-5. This value represents the highest voltage imposed on protected circuitry during worst-case surge events and is guaranteed across the full operating temperature range (−65 °C to +150 °C).
How does the SMB (DO-214AA) package of P6SMB82CAHM3_B/H affect PCB layout?
The SMB (DO-214AA) package of P6SMB82CAHM3_B/H requires a minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad per terminal for optimal thermal performance and surge current handling. Its low-profile design (max height 1.95 mm) supports high-density routing, and the absence of polarity marking simplifies placement. Thermal resistance is specified at RθJA = 100 °C/W under these pad conditions.
What is the significance of the "HM3" suffix in P6SMB82CAHM3_B/H?
The "HM3" suffix in P6SMB82CAHM3_B/H indicates halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance requirements - critical for automotive and industrial applications where material compliance and long-term interconnect reliability are mandated. It also confirms the device is built to Vishay's commercial-grade reliability standards with enhanced process controls for consistency.
