Overview
P6SMB82CAHM3_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 or power lines. It features a 82 V breakdown voltage (VBR min/max = 77.9 V / 86.1 V), 600 W peak pulse power (10/1000 µs), and clamps to ≤113 V at 5.3 A peak pulse current - deployed in automotive sensor interfaces, industrial I/O protection, and telecom line surge suppression.
For engineers reviewing the P6SMB82CAHM3_A/I datasheet, P6SMB82CAHM3_A/I pinout, P6SMB82CAHM3_A/I application, or P6SMB82CAHM3_A/I equivalent, this device delivers AEC-Q101-qualified transient immunity in SMB (DO-214AA) package with halogen-free RoHS compliance, low incremental surge resistance, and fast response time critical for ESD and lightning-induced surge protection in harsh environments.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction ensures stable clamping performance under repetitive surge events, and its MSL Level 1 rating supports lead-free reflow up to 260 °C peak temperature.
The device is rated for 150 °C maximum junction temperature and exhibits a typical thermal resistance of 100 °C/W (junction-to-ambient) on standard 0.2" × 0.2" copper pads. Its 0.106 g unit weight and DO-214AA mechanical outline enable high-density automated placement in space-constrained PCB layouts.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ85CA | Same SMB package, but lower 500 W PPPM, higher VC (120 V @ 5.0 A), and no AEC-Q101 qualification | Not approved for automotive use; limited to commercial/industrial grade designs with relaxed surge margin | Select when cost sensitivity outweighs automotive qualification and 600 W headroom is not required |
| SMCJ85CA | Larger SMC (DO-214AB) package, 1500 W PPPM, same VBR range, AEC-Q101 available (HM3 suffix) | Requires larger PCB area and higher mounting thermal mass; suited for higher-energy surge environments | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4 and board space permits larger footprint |
Compared with SMAJ85CA and SMCJ85CA, P6SMB82CAHM3_A/I uniquely balances AEC-Q101 compliance, 600 W capability, and SMB footprint - making it optimal for space-constrained automotive and industrial modules where qualification and moderate surge energy coexist.

FAQ
What does the "CA" suffix indicate in P6SMB82CAHM3_A/I?
The "CA" suffix denotes a bidirectional configuration: P6SMB82CAHM3_A/I provides symmetrical transient suppression in both polarities, with identical VBR, VWM, and VC values for positive and negative surges. This eliminates polarity concerns during PCB layout and simplifies design for AC-coupled or differential signal lines. Unlike unidirectional variants (e.g., P6SMB82AHM3_A/I), the CA version has no cathode band marking and functions identically regardless of terminal orientation.
Is P6SMB82CAHM3_A/I suitable for automotive applications?
Yes, P6SMB82CAHM3_A/I is AEC-Q101 qualified (denoted by the "HM3" suffix and "_A/I" tape-and-reel packaging), making it suitable for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. It meets stress tests for temperature cycling, high-temperature reverse bias, and surge endurance per AEC-Q101 Rev D. The device's 150 °C TJ max and MSL Level 1 rating further support under-hood deployment and lead-free reflow compatibility.
How does the "HM3" suffix differ from "E3" or "M3" in P6SMB82CAHM3_A/I?
The "HM3" suffix indicates halogen-free, RoHS-compliant construction with AEC-Q101 qualification - distinguishing it from "E3" (RoHS-compliant commercial grade) and "M3" (halogen-free RoHS-compliant commercial grade). Only HM3 and HE3 variants carry automotive qualification. The "_A/I" denotes 13-inch tape-and-reel packaging (3200 units/reel), whereas "_A/H" would indicate 7-inch reels (750 units/reel). All three suffixes share identical electrical specs but differ in reliability certification and material compliance.
What is the maximum clamping voltage of P6SMB82CAHM3_A/I under surge conditions?
The maximum clamping voltage (VC) of P6SMB82CAHM3_A/I is 113 V, measured at its rated peak pulse current (IPPM) of 5.3 A using the standard 10/1000 µs double-exponential waveform. This value is guaranteed across the full operating temperature range and represents the highest voltage the device allows across its terminals during worst-case transient events - critical for ensuring downstream components remain within absolute maximum ratings.
Can P6SMB82CAHM3_A/I be used in place of P6SMB82AHE3_B/I?
No - P6SMB82CAHM3_A/I is bidirectional (CA), while P6SMB82AHE3_B/I is unidirectional (A) and AEC-Q101 qualified (HE3). Their VBR, VWM, and clamping behavior differ fundamentally: the unidirectional part conducts only in reverse bias and requires correct polarity placement, whereas the CA version clamps equally in both directions. Substitution would require circuit redesign to accommodate polarity constraints and verify that 113 V clamping meets system requirements without directional dependence.
