Product details
Overview
P6SMB62CAHM3/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 V / 65.1 V), 85.0 V maximum clamping voltage at 7.1 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6SMB62CAHM3/H datasheet, P6SMB62CAHM3/H pinout, P6SMB62CAHM3/H application, or P6SMB62CAHM3/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification status, SMB (DO-214AA) package compatibility, and thermal resistance (RθJA = 100 °C/W) for board-level surge protection design.
Technical Context
The P6SMB62CAHM3/H operates as a bidirectional avalanche diode, conducting symmetrically in both polarities above its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low incremental surge resistance, enabling consistent clamping performance under repetitive 10/1000 μs transients at 0.01 % duty cycle.
Designed for surface-mount assembly on standard PCB copper pads (0.2" × 0.2"), it delivers 600 W peak pulse power dissipation without derating up to TA = 25 °C and maintains operation across -65 °C to +150 °C junction temperature range. The HM3 suffix confirms halogen-free, RoHS-compliant construction with AEC-Q101 qualification for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V - defines precise voltage threshold where avalanche conduction begins in either polarity; critical for matching system overvoltage trip levels. |
| VC @ IPPM | 85.0 V at 7.1 A - maximum clamped voltage seen by protected circuit during 10/1000 μs surge; determines worst-case stress on downstream components. |
| PPPM | 600 W - peak transient energy handling capacity with standardized waveform; enables robust protection against ESD, lightning-induced surges, and inductive switching spikes. |
| VWM | 53.0 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA; sets upper limit for normal-mode signal or bias rail voltage. |
| TJ max | +150 °C - maximum junction temperature; supports high-ambient deployments in engine compartments or industrial enclosures without thermal shutdown. |
| RθJA | 100 °C/W - thermal resistance from junction to ambient air; informs minimum copper pad area (0.2" × 0.2") required for safe power dissipation at rated pulse conditions. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional device with no polarity marking - terminals are symmetrical anode/cathode pair. Molding compound meets UL 94 V-0 flammability rating; matte tin-plated leads comply with J-STD-002 solderability and JESD 22-B102 whisker testing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward conduction (unidirectional mode); one side of bidirectional clamping path | Connected to line under protection; forms symmetrical clamp node with cathode - no functional distinction in bidirectional operation. |
| Cathode | Current exit point in forward conduction (unidirectional mode); other side of bidirectional clamping path | Connected to reference plane (e.g., ground or supply rail); completes low-impedance surge shunt path during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines (e.g., RS-485, CAN, sensor bridges) without polarity concerns. |
| AEC-Q101 qualified (HM3 suffix) | Validated for automotive applications including powertrain control modules and body electronics where reliability under thermal cycling and vibration is mandatory. |
| 600 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 3 (1 kV/2 Ω) surge immunity without external current limiting, reducing BOM count in industrial I/O designs. |
| Low clamping ratio (VC/VBR ≈ 1.34) | Minimizes voltage overshoot during transient events, preserving margin for 3.3 V/5 V logic interfaces and analog front-end components. |
| MSL Level 1 (260 °C peak reflow) | Compatible with standard lead-free SMT reflow profiles without moisture sensitivity handling - simplifies manufacturing logistics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64A-E3/5B | Unidirectional; VBR = 64–71.1 V; VC = 103 V @ 5.8 A; same SMB package but lacks AEC-Q101 qualification | Requires polarity-aware layout; suitable for DC-biased rails only; not approved for automotive use | Select when cost sensitivity outweighs automotive compliance needs and unidirectional clamping suffices. |
| SMCJ64CA-Q | Bidirectional; higher 1500 W PPPM; VC = 103 V @ 14.5 A; larger SMC (DO-214AB) package | Occupies more PCB area; better suited for high-energy surges like lightning-induced grid coupling | Choose for enhanced surge margin in outdoor telecom or solar inverter applications where space permits larger footprint. |

FAQ
What is the clamping voltage of the P6SMB62CAHM3/H under a 10/1000 μs surge?
The P6SMB62CAHM3/H has a maximum clamping voltage (VC) of 85.0 V at 7.1 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88370 and reflects worst-case voltage seen by protected circuitry during surge events - critical for verifying margin against downstream component absolute maximum ratings.
Is the P6SMB62CAHM3/H qualified for automotive applications?
Yes, the P6SMB62CAHM3/H carries the HM3 suffix, confirming it is halogen-free, RoHS-compliant, and AEC-Q101 qualified. This certification validates its suitability for automotive applications including engine control units, ADAS sensors, and body electronics where extended temperature operation (-65 °C to +150 °C) and reliability under thermal cycling are required.
What does the "CA" suffix indicate in P6SMB62CAHM3/H?
The "CA" suffix in P6SMB62CAHM3/H denotes a bidirectional configuration - meaning the device provides symmetrical transient voltage suppression in both polarities. Unlike unidirectional variants (e.g., P6SMB62AHM3/H), it requires no polarity alignment during placement and is ideal for AC-coupled or floating signal lines such as RS-485, CAN, or sensor bridge outputs.
What is the standoff voltage (VWM) of the P6SMB62CAHM3/H?
The standoff voltage (VWM) of the P6SMB62CAHM3/H is 53.0 V - the maximum continuous reverse voltage that can be applied without exceeding 1 μA leakage current. This parameter ensures reliable operation on 48 V DC systems or 36 V nominal automotive rails while maintaining low standby power loss and avoiding false triggering during normal operation.
Does the P6SMB62CAHM3/H require special PCB layout considerations?
Yes, the P6SMB62CAHM3/H must be mounted on minimum recommended copper pads: 0.2" × 0.2" (5.0 mm × 5.0 mm) per terminal to achieve specified thermal resistance (RθJA = 100 °C/W) and 600 W pulse power rating. Short, direct traces to protected nodes and low-inductance grounding are essential to preserve fast response time and minimize voltage overshoot during surge events.
