Product details
Overview
P6SMB100CAHM3_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 100 V standoff voltage (VWM), 137 V maximum clamping voltage at 4.4 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform.
For engineers reviewing the P6SMB100CAHM3_A/I datasheet, P6SMB100CAHM3_A/I pinout, P6SMB100CAHM3_A/I application, or P6SMB100CAHM3_A/I equivalent, key selection criteria include bidirectional transient suppression capability, SMB (DO-214AA) package compatibility, AEC-Q101 qualification status, and thermal resistance of 100 °C/W junction-to-ambient under standard mounting conditions.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity sensitivity. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 μA at 85.5 V), while the 100 °C/W thermal resistance reflects performance on 0.2" × 0.2" copper pads per terminal.
The device delivers 600 W peak pulse power handling with a 10/1000 μs waveform at 0.01% duty cycle, and exhibits a temperature coefficient of breakdown voltage of +0.106 %/°C - critical for stability across automotive (-65 °C to +150 °C) and industrial operating ranges.

Applications
| Automotive Sensor Protection | Industrial CAN Bus Interface |
|---|---|
Use Scenario: Protecting analog sensor outputs (e.g., pressure, temperature) in engine bay modules exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional TVS placed across differential sensor pair or supply rail to clamp transients before they reach ADC input or signal conditioner IC. Use Value: Maintains signal integrity under 100 V load dump events by limiting clamped voltage to 137 V while absorbing 600 W peak energy. | Use Scenario: Safeguarding CANH/CANL lines in industrial PLC gateways against EFT bursts and cable discharge events. IC Role / Device Role / Timing Role: Symmetrical transient suppressor installed between CANH and CANL, referenced to ground via low-inductance layout. Use Value: Prevents bus lockup during 4 kV EFT testing by clamping differential surges within 1 ns response time and holding voltage below transceiver damage threshold. |
| Telecom Power Input Stage | Consumer USB-C Port Protection |
Use Scenario: Input-stage surge protection for PoE-powered telecom equipment subjected to lightning-induced surges on 48 V DC lines. IC Role / Device Role / Timing Role: Primary bidirectional clamp on DC input rail upstream of DC-DC converter, coordinated with fuse and MOV. Use Value: Limits transient voltage to 137 V during 600 W 10/1000 μs surges, preventing overvoltage stress on downstream primary-side FETs and controller ICs. | Use Scenario: Secondary-level protection for USB-C CC and VCONN lines in portable devices against hot-plug ESD and cable coupling transients. IC Role / Device Role / Timing Role: Low-capacitance bidirectional TVS placed directly at connector pins to shunt ESD before reaching USB PD controller or level-shifter IC. Use Value: Provides sub-1 ns response with <1.0 μA leakage at 85.5 V, ensuring no impact on high-speed signaling while meeting IEC 61000-4-2 ±15 kV contact discharge requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Same VWM (85.5 V), VC = 137 V, but rated for 600 W with 10/1000 μs waveform and MSL Level 1; not AEC-Q101 qualified | Lacks automotive qualification; suitable for commercial/industrial use only | Select when AEC-Q101 compliance is not required and cost optimization is prioritized |
| 1.5SMC100CA | Higher package thermal resistance (RθJA = 125 °C/W), same VWM/VC ratings, but larger SMC (DO-214AB) footprint | Requires PCB layout change; better power dissipation margin but lower board density | Choose when higher sustained surge duty cycles demand improved thermal mass and layout allows SMC size |
Compared with P6SMB100CAHM3_A/I, SMBJ100CA offers identical electrical clamping but lacks automotive qualification, while 1.5SMC100CA provides equivalent protection in a larger package with higher thermal resistance - making P6SMB100CAHM3_A/I optimal for space-constrained AEC-Q101-compliant designs.

FAQ
What does the "CA" suffix indicate in P6SMB100CAHM3_A/I?
The "CA" suffix in P6SMB100CAHM3_A/I denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage suppression in both polarities. This eliminates the need for polarity-aware placement on PCBs and enables protection of AC-coupled, differential, or floating signal paths - unlike unidirectional variants (e.g., P6SMB100A) that require cathode orientation alignment. The CA variant is explicitly validated for bidirectional applications per Vishay's P6SMB datasheet revision 09-Jan-2024.
Is P6SMB100CAHM3_A/I qualified to AEC-Q101?
Yes, P6SMB100CAHM3_A/I is AEC-Q101 qualified, as confirmed by the "HM3" suffix and documentation in Vishay's P6SMB datasheet (Document Number: 88370, Revision: 09-Jan-2024). The HM3 designation indicates halogen-free, RoHS-compliant construction with full AEC-Q101 stress testing - including temperature cycling, humidity bias, and high-temperature operating life - making it suitable for automotive powertrain, body electronics, and ADAS applications.
What is the maximum clamping voltage of P6SMB100CAHM3_A/I and under what test condition?
The maximum clamping voltage (VC) of P6SMB100CAHM3_A/I is 137 V, measured at a peak pulse current (IPPM) of 4.4 A using a 10/1000 μs double-exponential waveform. This value is specified in the Electrical Characteristics table on page 2 of the Vishay P6SMB datasheet and represents the upper limit of voltage imposed on protected circuitry during worst-case transient events, assuming proper PCB layout with 0.2" × 0.2" copper pads per terminal.
How does the thermal resistance of P6SMB100CAHM3_A/I affect its surge handling capability?
The typical junction-to-ambient thermal resistance (RθJA) of P6SMB100CAHM3_A/I is 100 °C/W when mounted on 0.2" × 0.2" copper pads per terminal. This value directly impacts safe repetitive surge operation: at 600 W peak power, junction temperature rise reaches ~60 °C above ambient per pulse, limiting duty cycle to 0.01% per datasheet. Lower RθJA improves thermal margin for burst-mode surges, but P6SMB100CAHM3_A/I's rating assumes standard SMB pad layout - oversized copper or heatsinking is not required for single-event compliance.
Can P6SMB100CAHM3_A/I be used in place of a unidirectional TVS like P6SMB100AHM3_A/I?
No - P6SMB100CAHM3_A/I is bidirectional and lacks polarity marking, while P6SMB100AHM3_A/I is unidirectional with a cathode band. Substituting them requires verifying circuit topology: bidirectional use is mandatory for AC, differential, or floating rails; unidirectional types are required for DC supply rail protection where reverse polarity must be blocked. The clamping characteristics differ slightly (e.g., forward voltage drop applies only to unidirectional), so direct replacement without schematic and layout review may compromise protection integrity.
