Product details
Overview
SM6T10CA-E3/5B from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 10 V stand-off voltage (VWM), 12.8 V minimum breakdown voltage (VBR), 600 W peak pulse power (10/1000 μs), <1 μA reverse leakage at VWM, and clamps to ≤17.0 V at 35.3 A IPPM - used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the SM6T10CA-E3/5B datasheet, SM6T10CA-E3/5B pinout, SM6T10CA-E3/5B application, or SM6T10CA-E3/5B equivalent, key selection criteria include bidirectional clamping capability, SMB package thermal performance (RθJA = 100 °C/W), AEC-Q101 qualification eligibility (via HE3/HM3 variants), and compliance with IEC 61000-4-2/4-4/4-5 surge immunity standards.
Technical Context
The SM6T10CA-E3/5B operates as a symmetrical avalanche diode, conducting equally in both directions above its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low leakage (<1 μA at 10 V), while the low-inductance SMB package enables fast response (<1 ns) to ESD and lightning-induced transients.
It delivers 600 W peak pulse power under standardized 10/1000 μs waveform conditions with derating above 25 °C (per Fig. 2), and supports continuous power dissipation of 5.0 W on infinite heatsink at 50 °C. Junction temperature range spans −65 °C to +150 °C, meeting automotive under-hood thermal requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum steady-state reverse voltage before clamping begins; defines operating margin for 12 V nominal systems. |
| VBR (min/max) | 11.4 V / 12.6 V at 1 mA - ensures reliable turn-on during transients without false triggering during normal operation. |
| VC @ IPPM | ≤17.0 V at 35.3 A (10/1000 μs) - limits protected circuit voltage stress during worst-case surge events. |
| PPPM | 600 W - sustains high-energy transients per IEC 61000-4-5 Level 4 (4 kV line-to-earth). |
| RθJA | 100 °C/W - determines thermal rise under sustained power dissipation; requires ≥5 mm × 5 mm copper pads for rated performance. |
| TJ max. | +150 °C - enables use in under-hood automotive environments and industrial enclosures without forced cooling. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant, MSL level 1 (260 °C peak reflow). Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); cathode band omitted (bidirectional device has no polarity marking).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (reverse bias) | One terminal of symmetrical junction; conducts when voltage exceeds −VBR. |
| Cathode | Transient current entry (forward bias) | Second terminal of symmetrical junction; conducts when voltage exceeds +VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns. |
| 600 W peak pulse power (10/1000 μs) | Meets IEC 61000-4-5 surge immunity up to 4 kV in 2 Ω source impedance configurations. |
| Glass passivated junction | Ensures long-term stability of VBR and leakage across temperature and humidity stress. |
| Low inductance SMB package | Minimizes voltage overshoot during fast-rising transients (e.g., ESD >1 kV/ns). |
Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|
Use Scenario: Protecting CAN, LIN, or analog sensor inputs (e.g., pressure, temperature) from load dump and inductive switching spikes in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional TVS clamping element placed directly at connector entry point before signal conditioning circuitry. Use Value: Limits transient voltage to ≤17.0 V, preventing damage to downstream 12 V-tolerant op-amps and ADC front-ends. | Use Scenario: Shielding PLC digital input modules from surges induced by relay coil de-energization or field wiring faults. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 24 V DC input lines, coordinated with series current-limiting resistor. Use Value: Absorbs 600 W pulses without degradation, maintaining system uptime in factory automation environments. |
| Telecom Line Interface | Consumer USB Port Protection |
Use Scenario: Safeguarding Ethernet PHY interfaces (e.g., 10/100BASE-TX) against lightning-induced common-mode surges on unshielded twisted pair. IC Role / Device Role / Timing Role: Common-mode TVS pair (two devices) across differential pairs, referenced to chassis ground. Use Value: Clamps differential and common-mode transients simultaneously with matched VBR and VC characteristics. | Use Scenario: Secondary-level ESD protection on USB 2.0 D+/D− lines in smartphones and peripherals, downstream of primary polymer TVS. IC Role / Device Role / Timing Role: Low-capacitance (<50 pF) bidirectional clamp ensuring signal integrity while passing IEC 61000-4-2 ±15 kV contact discharge. Use Value: Adds robustness against repeated ESD events without degrading 480 Mbps data eye margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | Same SMB package, identical VWM/VBR/VC specs, but rated for 600 W with tighter VBR tolerance (±5 % vs. ±5 %), same RθJA. | No functional difference; validated for identical IEC 61000-4-2/4-5 test profiles. | Select SMBJ10CA if requiring legacy design continuity or distributor stock alignment. |
| P6SMB10CA | Identical electrical specs and SMB package; differs only in branding (Littelfuse) and tape/reel packaging code (e.g., P6SMB10CAHE3_A instead of SM6T10CA-E3/5B). | Drop-in replacement in all PCB layouts; same thermal and surge performance. | Choose P6SMB10CA for dual-sourcing flexibility where Vishay supply constraints exist. |
Compared with SM6T10CA-E3/5B, SMBJ10CA offers identical clamping behavior and thermal response but originates from a different product family with distinct qualification history, while P6SMB10CA provides full form-fit-function equivalence with alternate logistics coding - both enable seamless BOM substitution without layout or validation changes.

FAQ
What is the clamping voltage of SM6T10CA-E3/5B at its rated peak pulse current?
The SM6T10CA-E3/5B clamps to a maximum of 17.0 V at its rated peak pulse current (IPPM) of 35.3 A under the standard 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88385 and defines the upper voltage limit imposed on protected circuits during surge events.
Is SM6T10CA-E3/5B suitable for automotive applications?
Yes, SM6T10CA-E3/5B is qualified for automotive use when ordered with HE3 or HM3 suffixes (e.g., SM6T10CAHE3_B), which denote AEC-Q101 qualification. The base SM6T10CA-E3/5B is commercial grade but shares identical electrical and thermal specs - design-in for automotive requires explicit AEC-Q101 variant ordering.
What does the "CA" suffix indicate in SM6T10CA-E3/5B?
The "CA" suffix in SM6T10CA-E3/5B explicitly denotes a bidirectional configuration - meaning the device provides symmetrical clamping in both polarities, unlike unidirectional variants ending in "A". This eliminates polarity concerns during board assembly and supports AC signal line protection.
What is the thermal resistance of SM6T10CA-E3/5B, and how does it affect layout?
SM6T10CA-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To achieve rated power dissipation, PCB layout must provide at least this pad area - undersized pads cause excessive junction temperature rise and premature failure.
How does SM6T10CA-E3/5B compare to unidirectional SM6T10A-E3/5B in circuit implementation?
SM6T10CA-E3/5B replaces two unidirectional SM6T10A-E3/5B devices in back-to-back configuration, simplifying layout and reducing component count. Unlike SM6T10A-E3/5B, it has no polarity marking and conducts identically in both directions - ideal for protecting floating or AC-coupled nodes where voltage polarity is undefined.
