Product details
Overview
P6SMB10CAHM3_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 and power lines. It features a 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage at 41.4 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines in industrial and automotive electronics.
For engineers reviewing the P6SMB10CAHM3_A/I datasheet, P6SMB10CAHM3_A/I pinout, P6SMB10CAHM3_A/I application, or P6SMB10CAHM3_A/I equivalent, this device serves as a halogen-free, AEC-Q101-qualified TVS for bidirectional surge protection where low-profile SMB (DO-214AA) mounting, fast response time, and stable clamping under repetitive transients are required.
Technical Context
The P6SMB10CAHM3_A/I operates as a symmetrical bidirectional avalanche diode, with identical electrical characteristics in both directions due to its CA suffix designation. Its breakdown voltage is specified at 10.5 V minimum and 11.6 V maximum at 1 mA test current, and it exhibits a temperature coefficient of 0.075 %/°C for VBR.
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. The device is rated for operation from –65 °C to +150 °C and meets J-STD-020 MSL Level 1 with 260 °C reflow peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 10 V - Maximum continuous reverse voltage before significant leakage; defines operating margin before clamping begins. |
| VBR (Breakdown Voltage) | 10.5–11.6 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 14.5 V at 41.4 A IPPM - Peak voltage seen by protected circuit during 600 W transient; critical for downstream IC survival. |
| PPPM (Peak Pulse Power) | 600 W - Sustains single 10/1000 μs surges without failure; enables robust protection against lightning-induced or inductive-switching spikes. |
| ID (Reverse Leakage) | 5.0 μA max at 10 V - Low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| Package | SMB (DO-214AA) - Surface-mount footprint with 5.59 mm × 4.06 mm body; compatible with automated placement and IPC-7351B land patterns. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock per AEC specification. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, MSL Level 1, 260 °C reflow compatible. Bidirectional construction means no polarity marking; terminals are symmetrical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Both terminals function identically; conducts in either direction once VWM is exceeded - eliminates orientation concerns during layout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CA | Same VWM (10 V) and VC (14.5 V), but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA). | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 or automotive load-dump. | Select when board space is constrained and surge threat level is ≤400 W (e.g., consumer USB ports). |
| SMCJ10CA | Same VWM and VC, but higher PPPM (1500 W); larger SMC (DO-214AB) package with lower RθJA (35 °C/W). | Overqualified for 600 W needs; requires more PCB area and may increase cost unnecessarily. | Choose only if future design scaling requires headroom beyond 600 W or thermal performance demands <50 °C/W. |
Compared with SMAJ10CA and SMCJ10CA, the P6SMB10CAHM3_A/I delivers optimal balance of 600 W surge capacity, SMB footprint efficiency, AEC-Q101 qualification, and halogen-free compliance - making it the preferred choice for mid-tier industrial and automotive signal-line protection where size, reliability, and standard-compliance are jointly critical.

FAQ
What does the "CA" suffix mean in P6SMB10CAHM3_A/I?
The "CA" suffix in P6SMB10CAHM3_A/I denotes a bidirectional configuration - meaning the device provides symmetrical transient voltage suppression in both polarities. Unlike unidirectional variants (e.g., P6SMB10A), the P6SMB10CAHM3_A/I has no cathode marking and functions identically regardless of terminal orientation, making it ideal for AC signal lines, differential buses, and applications where polarity cannot be guaranteed during installation or operation.
Is P6SMB10CAHM3_A/I qualified for automotive use?
Yes, P6SMB10CAHM3_A/I is AEC-Q101 qualified, as confirmed by its HM3 suffix and documentation in Vishay's P6SMB datasheet (Rev. 09-Jan-2024). This qualification covers stress tests including temperature cycling, high-temperature operating life, and mechanical shock - validating its suitability for under-hood and chassis-mounted automotive electronics such as body control modules, sensor interfaces, and infotainment power supplies.
What is the maximum clamping voltage of P6SMB10CAHM3_A/I under surge conditions?
The maximum clamping voltage (VC) of P6SMB10CAHM3_A/I is 14.5 V, measured at its peak pulse current (IPPM) of 41.4 A using the standardized 10/1000 μs waveform. This value represents the highest voltage that will appear across protected circuitry during a full 600 W transient event - a critical parameter for ensuring downstream ICs (e.g., CAN transceivers or ADC front-ends) remain within absolute maximum ratings.
How does the HM3 suffix differ from E3 or M3 in the P6SMB10CAHM3_A/I part number?
The HM3 suffix in P6SMB10CAHM3_A/I indicates halogen-free, RoHS-compliant construction with AEC-Q101 qualification - distinguishing it from E3 (RoHS-compliant commercial grade) and M3 (halogen-free RoHS-compliant commercial grade). The "H" prefix confirms automotive qualification, while "M3" specifies halogen-free molding compound and matte tin terminations meeting JESD201 Class 2 whisker resistance, essential for long-life automotive deployments.
Can P6SMB10CAHM3_A/I be used in place of unidirectional TVS diodes like P6SMB10A?
No - P6SMB10CAHM3_A/I is strictly bidirectional and must not replace unidirectional types like P6SMB10A in DC-biased circuits where forward conduction must be blocked. In a unidirectional application (e.g., protecting a 12 V supply rail), using P6SMB10CAHM3_A/I would allow unintended forward current flow during normal operation. Always match device polarity to circuit topology: use P6SMB10A for DC rails and P6SMB10CAHM3_A/I only for AC, differential, or polarity-agnostic signal paths.
