Product details
Overview
SM6T10CA-M3/5B from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping ESD and surge transients on signal/power lines. It features 10 V standoff voltage (VWM), 11.3 V minimum breakdown voltage (VBR), 600 W peak pulse power (10/1000 μs), <1.0 μA reverse leakage at VWM, and clamps to ≤16.7 V at 36 A peak pulse current. It is widely deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SM6T10CA-M3/5B datasheet, SM6T10CA-M3/5B pinout, SM6T10CA-M3/5B application, or SM6T10CA-M3/5B equivalent, key selection criteria include bidirectional clamping capability, SMB footprint compatibility, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and compliance with halogen-free and RoHS requirements per M3 suffix.
Technical Context
The SM6T10CA-M3/5B operates as a symmetrical avalanche diode with identical forward and reverse breakdown characteristics due to its bidirectional CA construction. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low leakage across -65 °C to +150 °C operating range.
It delivers 600 W transient suppression under standardized 10/1000 μs waveform with clamping voltage of 16.7 V at 36 A, enabling robust protection of downstream MOSFETs, microcontrollers, and analog front-ends without sacrificing signal integrity. Thermal performance is defined by RθJL = 20 °C/W and RθJA = 100 °C/W on 5.0 mm × 5.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse voltage before significant leakage; sets operating margin for 12 V rail protection. |
| VBR (min/max) | 11.3 V / 12.6 V - Avalanche onset range at 1 mA test current; defines reliable turn-on threshold under transients. |
| VC @ IPPM | 16.7 V at 36 A - Clamped voltage during 600 W 10/1000 μs surge; determines maximum stress on protected IC. |
| PPPM | 600 W - Peak pulse power handling; supports IEC 61000-4-5 Level 4 (4 kV) surge immunity when properly laid out. |
| ID @ VWM | <1.0 μA - Reverse leakage at standoff voltage; ensures negligible standby power loss in battery-powered systems. |
| Package | SMB (DO-214AA) - Surface-mount outline with 2.20 mm max height; compatible with automated SMT placement and reflow. |
| TJ max | +150 °C - Maximum junction temperature; enables use in under-hood automotive environments. |
Pinout & Package
SM6T10CA-M3/5B uses an SMB (DO-214AA) surface-mount package with two terminals: no polarity marking for bidirectional operation. The device has no cathode/anode designation; both terminals behave identically under reverse or forward transient conditions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Transient input/output node | Connected to line under protection (e.g., CAN_H or RS-485 A); conducts surge current symmetrically in either direction. |
| Terminal 2 | Transient input/output node | Connected to reference plane (e.g., ground or differential complement); completes low-inductance clamping path. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR and VC in both polarities - eliminates need for orientation-aware layout in differential or AC-coupled lines. |
| 600 W peak pulse power | Withstands IEC 61000-4-5 4 kV surge (10/1000 μs) on 5.0 mm × 5.0 mm PCB pads - reduces need for external series impedance. |
| Halogen-free & RoHS-compliant (M3) | Meets JEDEC JESD201 Class 2 whisker resistance and UL 94 V-0 flammability - suitable for automotive and industrial end-equipment. |
| Low clamping ratio (VC/VBR ≈ 1.48) | Minimizes overvoltage overshoot during fast transients - protects 3.3 V and 5 V logic interfaces without additional buffering. |
| AEC-Q101 qualified option available | HM3 variant meets automotive reliability standards - SM6T10CA-M3/5B itself is commercial-grade but shares identical die and package design. |

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 SMB package, 600 W rating, but VWM = 10 V, VBR = 11.1–12.3 V, VC = 17.0 V @ 35.3 A; higher RθJA (125 °C/W). | Marginally higher clamping voltage; less effective for tight 12 V rail margins; lower thermal efficiency on small pads. | Select SMAJ10CA only if legacy design reuse or dual-sourcing requires identical JEDEC MO-213AA footprint with known qualification history. |
| 1.5KE10CA | Through-hole DO-201 package, 1500 W rating, VWM = 10 V, VBR = 11.1–12.3 V, VC = 17.0 V @ 88.2 A; not surface-mountable. | Requires PCB through-hole real estate and wave soldering; unsuitable for high-density or automated SMT production. | Choose 1.5KE10CA only for prototyping, low-volume repair, or where mechanical robustness outweighs board space constraints. |
Compared with SMAJ10CA and 1.5KE10CA, SM6T10CA-M3/5B offers superior thermal performance (RθJA = 100 °C/W vs. 125 °C/W), halogen-free compliance (M3), and optimized SMB footprint for modern SMT lines-making it preferred for volume automotive and industrial designs requiring AEC-Q101-ready scalability.

FAQ
What does the "CA" suffix indicate in SM6T10CA-M3/5B?
The "CA" suffix in SM6T10CA-M3/5B denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage suppression in both polarities. Unlike unidirectional variants (e.g., SM6T10A), SM6T10CA-M3/5B has no cathode marking and functions identically whether voltage is applied terminal-to-terminal in either direction-ideal for AC lines, differential buses like RS-485, or ungrounded sensor outputs.
Is SM6T10CA-M3/5B AEC-Q101 qualified?
SM6T10CA-M3/5B is the commercial-grade halogen-free variant; it is not AEC-Q101 qualified. However, the HM3-suffixed version (e.g., SM6T10CAHM3_B/I) carries full AEC-Q101 qualification. Both share identical die, SMB package, electrical specs, and thermal characteristics-only the test documentation and traceability differ. For automotive production, specify HM3 suffix variants.
What is the maximum clamping voltage of SM6T10CA-M3/5B under surge conditions?
The maximum clamping voltage (VC) of SM6T10CA-M3/5B is 16.7 V when subjected to a 10/1000 μs waveform at its rated peak pulse current of 36 A. This value is guaranteed per Vishay's datasheet (Document Number: 88385, Rev. 09-Jan-2024) and represents the upper limit of voltage seen by protected circuitry during worst-case surge events.
Can SM6T10CA-M3/5B be used in place of SM6T10A in existing designs?
SM6T10CA-M3/5B cannot directly replace SM6T10A without layout review: SM6T10A is unidirectional (cathode-banded) and must be oriented correctly, whereas SM6T10CA-M3/5B is bidirectional with no polarity marking. If the original design relies on directional conduction (e.g., DC rail protection), substitution may cause improper clamping. Verify circuit topology before interchange.
What does the "M3/5B" packaging code mean for SM6T10CA-M3/5B?
The "M3/5B" suffix in SM6T10CA-M3/5B indicates halogen-free, RoHS-compliant construction (M3) supplied in 13-inch plastic tape-and-reel format with 3200 units per reel (5B). This packaging supports high-speed SMT assembly and meets environmental compliance requirements for industrial and automotive supply chains without requiring process changes.
