Product details
Overview
P6SMB62CAHM3_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 62 V breakdown voltage (VBR min/max = 58.9–65.1 V), 600 W peak pulse power (10/1000 µs), and clamps to ≤85.0 V at 7.1 A peak pulse current - used in automotive sensor interface protection per AEC-Q101 qualification.
For engineers reviewing the P6SMB62CAHM3_B/H datasheet, P6SMB62CAHM3_B/H pinout, P6SMB62CAHM3_B/H application, or P6SMB62CAHM3_B/H equivalent, key selection criteria include bidirectional clamping capability, SMB (DO-214AA) package compatibility, AEC-Q101 qualification status, and thermal resistance (RθJA = 100 °C/W) for board-level transient suppression in harsh environments.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR, VWM, and IPPM specifications in forward and reverse directions. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for protecting sensitive inputs against ESD and inductive switching spikes.
The device is rated for 150 °C maximum junction temperature and meets J-STD-020 MSL Level 1 (peak reflow 260 °C). Its halogen-free, RoHS-compliant construction (HM3 suffix) and AEC-Q101 qualification (B/H suffix) confirm suitability for automotive-grade PCB assembly without derating penalties.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V - ensures reliable conduction onset above normal operating voltage while avoiding false triggering |
| VWM | 53.0 V - maximum continuous reverse stand-off voltage before leakage exceeds 1 µA |
| VC @ IPPM | 85.0 V at 7.1 A - clamped voltage during 600 W transient, defining worst-case stress on downstream ICs |
| PPPM | 600 W - peak pulse power handling with 10/1000 µs waveform, supporting repetitive surge events at 0.01% duty cycle |
| RθJA | 100 °C/W - thermal resistance from junction to ambient, requiring minimum 0.2" × 0.2" copper pads for rated power dissipation |
| TJ max | +150 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| AEC-Q101 | Qualified - validated for automotive reliability including temperature cycling, HTRB, and ESD per AEC standard |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional - no polarity marking; symmetrical terminals function as anode and cathode depending on transient polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | Either terminal conducts when voltage exceeds ±VBR; no fixed polarity - used interchangeably across differential or single-ended lines |
| Terminal 2 | Anode/Cathode (bidirectional) | Paired terminal completing the bidirectional clamp path; requires equal trace impedance for balanced transient suppression |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns |
| 600 W peak pulse power | Withstands high-energy transients such as ISO 7637-2 Pulse 1/2a/5a in automotive ECUs without degradation |
| AEC-Q101 qualified (HM3_B/H) | Validated for automotive use including temperature cycling, humidity bias, and mechanical shock per AEC standard |
| Halogen-free & RoHS-compliant | Meets environmental compliance requirements for Tier 1 automotive supply chains and industrial CE-marked equipment |
| MSL Level 1 rating | Allows direct placement into lead-free reflow profiles up to 260 °C peak without pre-baking |
Applications
| Automotive Sensor Interface | Industrial CAN Bus Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64CA | Same SMB package, 64 V VBR, but only commercial-grade (no AEC-Q101); RθJA = 110 °C/W | Lacks automotive qualification and has higher thermal resistance - suitable for cost-sensitive industrial designs only | Select when AEC-Q101 is not required and board layout allows marginally higher thermal rise |
| 1.5KE62CA | Through-hole DO-15 package, same 62 V rating, 600 W rating, but larger footprint and lower mounting density | Not compatible with automated SMT lines; unsuitable for space-constrained automotive PCBs | Choose only for legacy through-hole designs or prototyping where rework tolerance outweighs size constraints |
Compared with P6SMB62CAHM3_B/H, SMAJ64CA offers similar electrical performance but lacks automotive qualification and thermal efficiency, while 1.5KE62CA provides identical surge capability in a legacy through-hole form factor incompatible with modern SMT production.

FAQ
What is the breakdown voltage range of the P6SMB62CAHM3_B/H?
The P6SMB62CAHM3_B/H has a specified breakdown voltage (VBR) range of 58.9 V to 65.1 V at 1.0 mA test current. This bidirectional tolerance ensures consistent clamping behavior across manufacturing lots and temperature extremes, directly supporting design margin calculations for 48 V and 60 V automotive subsystems where the P6SMB62CAHM3_B/H is commonly deployed.
Is the P6SMB62CAHM3_B/H suitable for automotive applications?
Yes, the P6SMB62CAHM3_B/H is AEC-Q101 qualified (denoted by the HM3_B/H suffix), with validation across temperature cycling, high-temperature reverse bias, and ESD testing per automotive standards. Its halogen-free, RoHS-compliant construction and MSL Level 1 rating make the P6SMB62CAHM3_B/H appropriate for engine control units, ADAS sensors, and body electronics in production vehicles.
What does the "CA" suffix mean in P6SMB62CAHM3_B/H?
The "CA" suffix in P6SMB62CAHM3_B/H indicates a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities, with identical VBR, VC, and IPPM characteristics regardless of voltage polarity. This eliminates the need for orientation-aware placement and simplifies layout for differential or AC-coupled signal paths where the P6SMB62CAHM3_B/H is applied.
How does the P6SMB62CAHM3_B/H compare to unidirectional variants like P6SMB62AHM3_B/H?
The P6SMB62CAHM3_B/H differs from unidirectional P6SMB62AHM3_B/H in its symmetrical clamping behavior: it conducts during overvoltage events of either polarity, whereas the unidirectional version only clamps in reverse bias. The P6SMB62CAHM3_B/H is preferred for protecting floating or AC signals (e.g., CAN, RS-485), while the unidirectional variant suits DC power rail protection where polarity is fixed.
What is the maximum clamping voltage of the P6SMB62CAHM3_B/H under surge conditions?
The P6SMB62CAHM3_B/H clamps to a maximum of 85.0 V at its rated peak pulse current of 7.1 A (10/1000 µs waveform). This value defines the upper voltage limit imposed on protected circuitry during transient events and is critical for ensuring downstream components - such as microcontrollers or transceivers - remain within their absolute maximum ratings when the P6SMB62CAHM3_B/H is deployed.
