Product details
Overview
P6SMB62CAHM3_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 53.0 V standoff voltage (VWM), 65.1 V maximum breakdown voltage (VBR), 85.0 V clamping voltage (VC) at 7.1 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6SMB62CAHM3_A/I datasheet, P6SMB62CAHM3_A/I pinout, P6SMB62CAHM3_A/I application, or P6SMB62CAHM3_A/I equivalent, key selection considerations include bidirectional clamping symmetry, AEC-Q101 qualification status, SMB (DO-214AA) package thermal resistance (RθJA = 100 °C/W), low leakage (<1.0 μA at VWM), and halogen-free RoHS compliance per HM3 suffix.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, delivering identical clamping performance regardless of transient polarity - critical for AC-coupled or floating signal lines. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance under repetitive 10/1000 μs surges at 0.01% duty cycle.
The device is rated for 150 °C maximum junction temperature and meets J-STD-020 MSL Level 1 (peak reflow ≤260 °C), enabling compatibility with standard SMT assembly processes. Its SMB (DO-214AA) package provides 5.0 mm × 5.0 mm copper pad thermal dissipation per terminal, supporting 5.0 W steady-state power dissipation at TA = 50 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff) | 53.0 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold |
| VBR (Breakdown) | 58.9–65.1 V at 1.0 mA - Confirmed avalanche initiation range; ensures reliable turn-on during transients |
| VC (Clamping) | 85.0 V at 7.1 A (10/1000 μs) - Peak voltage seen by protected circuit during worst-case surge; limits stress on downstream components |
| PPPM | 600 W - Peak transient energy absorption capacity; supports IEC 61000-4-5 Level 4 surge immunity testing |
| IPPM | 7.1 A - Maximum non-repetitive surge current the device safely clamps without degradation |
| TJ max | 150 °C - Enables operation in under-hood automotive or high-ambient industrial environments |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 2.2 mm height and 3.94 mm length; compatible with automated pick-and-place |
Pinout & Package

| MSL Level 1 moisture sensitivity | Enables use without dry-pack or baking prior to reflow; compatible with standard SMT production flow at peak 260 °C |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
|
Use Scenario: Protecting CAN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load-dump and inductive switching transients in 12 V/24 V vehicle subsystems. IC Role / Device Role: Bidirectional clamping element placed across differential signal pairs or supply rails to limit transient excursions. Use Value: Prevents latch-up or permanent damage to microcontrollers and analog front-ends while maintaining signal integrity due to symmetric clamping behavior. |
Use Scenario: Safeguarding digital input modules in programmable logic controllers against field-wiring surges, electrostatic discharge, and relay coil flyback in factory automation. IC Role / Device Role: Primary transient suppression component installed at connector entry points on 24 V DC input channels. Use Value: Ensures system uptime by absorbing 600 W surges without failure, meeting IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge) immunity requirements. |
| Telecom Line Interface Protection | Consumer Power Adapter ESD Guard |
|
Use Scenario: Shielding Ethernet PHY interfaces, RS-485 transceivers, and PoE injectors from lightning-induced surges and cable discharge events in outdoor telecom cabinets. IC Role / Device Role: First-line protection device placed between connector and IC, operating in bidirectional mode to handle AC-coupled signals. Use Value: Maintains data integrity by clamping transients to ≤85.0 V within nanoseconds, preventing bit errors or PHY reset during surge events. |
Use Scenario: Adding secondary-level surge protection on AC-DC adapter output rails (e.g., 5 V/12 V USB-C PD outputs) to meet UL 62368-1 transient immunity requirements. IC Role / Device Role: Secondary TVS deployed after primary MOV or fuse, providing precise low-leakage clamping for sensitive downstream regulators. Use Value: Reduces risk of overvoltage shutdown in buck converters by limiting transient overshoot to <85 V while drawing <1.0 μA at nominal output voltage. |
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 | Unidirectional variant with same VWM/VC specs but asymmetric conduction; lacks bidirectional symmetry | Requires polarity-aware layout; unsuitable for AC or floating lines where polarity reversal occurs | Select only when unidirectional DC rail protection is confirmed and PCB space allows orientation-sensitive placement |
| SMCJ64CA | Higher 1500 W PPPM, larger SMC (DO-214AB) package, RθJA = 35 °C/W - lower thermal resistance but 2× footprint area | Used where higher surge margin is required (e.g., mains-connected equipment), but incompatible with dense SMB layouts | Choose when surge test levels exceed 600 W or board thermal design cannot accommodate SMB's 100 °C/W junction-to-ambient rise |
Compared with SMAJ64CA and SMCJ64CA, P6SMB62CAHM3_A/I delivers verified bidirectional clamping in the smallest standardized surface-mount TVS footprint (SMB), making it optimal for space-constrained automotive and industrial modules where polarity-agnostic protection and AEC-Q101 qualification are mandatory.

FAQ
What does the "CA" suffix indicate in P6SMB62CAHM3_A/I?
The "CA" suffix in P6SMB62CAHM3_A/I denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage clamping in both polarities. Unlike unidirectional variants (e.g., P6SMB62AHM3_A/I), this version has no cathode band marking and functions identically whether positive or negative transients occur - essential for protecting AC-coupled or floating signal paths without polarity constraints.
Is P6SMB62CAHM3_A/I qualified for automotive applications?
Yes, P6SMB62CAHM3_A/I is AEC-Q101 qualified, as confirmed by its HM3 suffix and documentation in Vishay's P6SMB series datasheet (Document Number: 88370, Revision: 09-Jan-2024). This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD, validating its suitability for under-hood and chassis-mounted automotive electronics such as body control modules and sensor interfaces.
What is the clamping voltage of P6SMB62CAHM3_A/I at its rated peak pulse current?
The clamping voltage (VC) of P6SMB62CAHM3_A/I is 85.0 V at 7.1 A peak pulse current with a 10/1000 μs waveform. This value is measured per standard test conditions (TA = 25 °C, mounted on 0.2" × 0.2" copper pads), and represents the maximum voltage imposed on the protected circuit during a worst-case transient event - a critical parameter for ensuring downstream ICs remain within absolute maximum ratings.
How does the HM3 suffix affect the environmental compliance of P6SMB62CAHM3_A/I?
The HM3 suffix in P6SMB62CAHM3_A/I indicates halogen-free, RoHS-compliant construction per IPC-4101D/21 and JEDEC J-STD-609A Class 1, with no brominated or chlorinated flame retardants. It retains UL 94 V-0 flammability rating and meets whisker resistance per JESD 201 Class 2 - ensuring compatibility with green manufacturing standards while maintaining electrical and thermal performance identical to non-halogen-free variants.
Can P6SMB62CAHM3_A/I replace P6SMB62AHE3_B/I in a design?
No - P6SMB62CAHM3_A/I is bidirectional (CA), while P6SMB62AHE3_B/I is unidirectional (A) and AEC-Q101 qualified (HE3_B). Their polarity behavior, marking, and conduction characteristics differ fundamentally. Substitution would require layout revision to accommodate cathode orientation and may compromise protection on AC or polarity-reversing lines. Always verify functional equivalence using Vishay's official cross-reference tools before replacement.
