Product details
Overview
P6SMB62CAHM3/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), 62.0 V minimum breakdown voltage (VBR), 85.0 V maximum clamping voltage (VC) at 7.1 A peak pulse current (IPPM), and 600 W peak pulse power capability with a 10/1000 μs waveform - used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P6SMB62CAHM3/I datasheet, P6SMB62CAHM3/I pinout, P6SMB62CAHM3/I application, or P6SMB62CAHM3/I equivalent, key selection criteria include bidirectional clamping symmetry, MSL Level 1 moisture sensitivity, halogen-free RoHS compliance, AEC-Q101 qualification status, and SMB (DO-214AA) package thermal performance under repetitive surge conditions.
Technical Context
This device operates as a voltage-clamped shunt protector: during transient overvoltage events exceeding its breakdown threshold, it rapidly switches to low-impedance conduction to divert surge current away from downstream circuitry. Its bidirectional architecture ensures symmetrical clamping in both polarities without polarity dependence.
It delivers 600 W peak pulse power handling per the 10/1000 μs standard waveform, with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling reliable operation up to 150 °C junction temperature. The glass-passivated junction ensures stable leakage and fast response time (<1 ns).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 53.0 V - Maximum continuous reverse operating voltage before clamping initiates; defines safe working range for protected line. |
| VBR (min) | 58.9 V - Minimum voltage at which device enters avalanche breakdown under 1 mA test current; guarantees consistent turn-on threshold. |
| VC @ IPPM | 85.0 V - Clamped voltage across device at 7.1 A peak pulse current; determines maximum stress imposed on protected IC or MOSFET. |
| PPPM | 600 W - Peak pulse power dissipation capability with 10/1000 μs waveform; supports high-energy transient suppression in industrial environments. |
| TJ max | +150 °C - Maximum allowable junction temperature; enables use in under-hood automotive or high-ambient industrial applications. |
| Package | SMB (DO-214AA) - Surface-mount package with 5.0 mm × 5.0 mm copper pad thermal footprint; meets UL 94 V-0 flammability rating. |

Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|
|

IC Role / Device Role / Timing Role: Shunt-type transient suppressor placed directly at connector or IC input pins to clamp overvoltage before reaching sensitive circuitry. Use Value: Maintains signal integrity by limiting clamped voltage to 85.0 V while surviving 600 W surges - prevents latch-up or gate oxide damage in 5 V/12 V automotive ICs. |
Use Scenario: Safeguarding PLC digital input modules against induced surges from nearby motor contactors or solenoid switching. IC Role / Device Role / Timing Role: Bidirectional voltage clamp on 24 V DC field wiring to absorb repetitive inductive kickback without polarity constraints.

| Telecom Line Protection | Consumer Power Adapter Input |
|
Use Scenario: Shielding Ethernet PHY front-end circuits and PoE injectors from lightning-induced surges on twisted-pair cabling. IC Role / Device Role / Timing Role: Primary-level surge suppressor located at board edge before isolation transformers or data-line filters. Use Value: Fast sub-nanosecond response and symmetrical bidirectional clamping ensure minimal signal distortion on differential pairs up to 100 MHz. |
Use Scenario: Secondary-side transient suppression on 12–24 V DC outputs of wall adapters powering IoT hubs or smart home controllers. IC Role / Device Role / Timing Role: Final-stage overvoltage guard between power supply output and downstream microcontroller or communication IC. Use Value: Halogen-free, RoHS-compliant construction meets global safety certifications; 150 °C max junction temperature supports sealed enclosure thermal profiles. |
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 min, 100 V VC @ 6.1 A - higher clamping voltage, lower peak pulse current (400 W). | Limited to lower-energy transients; not AEC-Q101 qualified. | Select when cost sensitivity outweighs automotive qualification or when system-level clamping margin allows higher VC. |
| SMCJ64CA | Higher-power SMC package (1500 W PPPM), same 64 V VBR min, 103 V VC @ 14.5 A - larger footprint, greater thermal mass. | Used where sustained surge energy exceeds P6SMB62CAHM3/I capability, e.g., main power rail protection. | Choose when PCB space permits and system-level surge testing requires >600 W handling capacity. |
Compared with SMAJ64CA and SMCJ64CA, P6SMB62CAHM3/I offers optimal balance of AEC-Q101 qualification, compact SMB footprint, and 600 W surge rating - making it preferred for space-constrained automotive and industrial edge nodes where qualification and reliability are mandatory.

FAQ
What is the clamping voltage of P6SMB62CAHM3/I at its rated peak pulse current?
The P6SMB62CAHM3/I has a maximum clamping voltage (VC) of 85.0 V when subjected to its rated peak pulse current (IPPM) of 7.1 A using the standard 10/1000 μs waveform. This value is measured per the test conditions specified in the Vishay datasheet (Document Number: 88370), and defines the upper voltage limit imposed on protected circuitry during surge events. The P6SMB62CAHM3/I maintains this clamping performance across its full operating temperature range.
Is P6SMB62CAHM3/I suitable for automotive applications?
Yes, P6SMB62CAHM3/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant, and automotive-grade construction. It is explicitly rated for use in automotive subsystems including engine control units, body electronics, and ADAS sensor interfaces. The P6SMB62CAHM3/I meets stringent requirements for thermal cycling, humidity resistance, and surge endurance defined in AEC-Q101 Rev G.
What does the "CA" suffix indicate in P6SMB62CAHM3/I?
The "CA" suffix in P6SMB62CAHM3/I denotes a bidirectional configuration - meaning the device provides symmetrical transient voltage suppression for both positive and negative polarity surges without requiring polarity-aware PCB layout. Unlike unidirectional variants (e.g., P6SMB62AHM3/I), the P6SMB62CAHM3/I has no cathode band marking and functions identically regardless of mounting orientation.
What is the standoff voltage (VWM) of P6SMB62CAHM3/I, and why does it matter?
The standoff voltage (VWM) of P6SMB62CAHM3/I is 53.0 V - the maximum continuous DC or RMS voltage the device can withstand without entering avalanche conduction. This parameter ensures normal circuit operation without leakage or power loss, while still allowing rapid clamping when transients exceed the 58.9 V minimum breakdown voltage. Selecting a VWM ≥10–20% above the system's maximum operating voltage prevents false triggering in P6SMB62CAHM3/I deployments.
How does the SMB (DO-214AA) package of P6SMB62CAHM3/I affect thermal performance?
The SMB (DO-214AA) package of P6SMB62CAHM3/I provides a thermal resistance of 100 °C/W (junction-to-ambient) when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This enables effective heat dissipation during repetitive surge events, supporting continuous operation up to +150 °C junction temperature. The P6SMB62CAHM3/I's low RθJA value makes it viable for high-density layouts where airflow is limited, such as sealed automotive control modules.
