Product details
Overview
SM6T10CA-E3/52 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 10 V standoff voltage (VWM), 11.3 V minimum breakdown voltage (VBR), 600 W peak pulse power (10/1000 μs), <1 μA reverse leakage at VWM, and clamps to ≤16.7 V at 36 A peak pulse current - used in automotive sensor line protection and industrial I/O interface surge suppression.
For engineers reviewing the SM6T10CA-E3/52 datasheet, SM6T10CA-E3/52 pinout, SM6T10CA-E3/52 application, or SM6T10CA-E3/52 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification eligibility (via HE3 suffix variants), SMB footprint compatibility, low clamping ratio (VC/VBR ≈ 1.48), and thermal resistance (RθJA = 100 °C/W) for board-level transient immunity design.
Technical Context
The SM6T10CA-E3/52 operates as a bidirectional avalanche diode with symmetrical clamping in both polarities, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1 μA at 10 V), while the low-inductance SMB package supports fast transient response under 10/1000 μs surge conditions.
It delivers 600 W peak pulse power per IEC 61000-4-5 Level 4 compliance when mounted on 5.0 mm × 5.0 mm copper pads, with thermal derating above 25 °C per Fig. 2 and maximum junction temperature of +150 °C. The device is not intended for continuous forward conduction but optimized for transient energy absorption only.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum steady-state reverse voltage before clamping begins; defines safe operating window for protected circuitry. |
| VBR (min) | 11.3 V at 1 mA - Guaranteed avalanche initiation threshold; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | ≤16.7 V at 36 A (10/1000 μs) - Clamped voltage seen by downstream ICs; limits stress on 12 V-rated components. |
| PPPM | 600 W - Peak transient power handling capacity; supports IEC 61000-4-5 4th-level surge immunity testing. |
| ID @ VWM | <1 μA - Negligible standby leakage; avoids signal integrity degradation in high-impedance sensor interfaces. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance; requires adequate PCB copper area for sustained surge duty cycles. |
Pinout & Package
SMB (DO-214AA) surface-mount package with molded plastic body, matte tin-plated leads, and no polarity marking (bidirectional configuration). Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); compliant with J-STD-020 MSL Level 1 (peak reflow 260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Enables robust protection against lightning-induced surges and inductive switching transients in automotive and industrial environments. |
| Low clamping voltage (VC/VBR ≈ 1.48) | Minimizes voltage overshoot across protected ICs, preserving margin for 12 V logic and analog front-ends. |
| MSL Level 1 moisture sensitivity | Allows standard SMT reflow without baking; reduces manufacturing complexity and cost in high-volume assembly. |
| Glass-passivated junction | Ensures long-term stability of breakdown characteristics and low leakage drift over temperature and lifetime. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ESD in engine control units. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed between signal line and chassis ground to shunt transient energy before it reaches the transceiver input stage. Use Value: Maintains signal integrity during ISO 7637-2 Pulse 5a (load dump) events up to 60 V, with clamping below 17 V to prevent damage to 12 V-rated PHY layers. | Use Scenario: Safeguarding digital input modules in programmable logic controllers exposed to relay coil flyback and field wiring surges. IC Role / Device Role / Timing Role: Parallel-connected transient suppressor on 24 V DC input channels to limit voltage excursion during inductive kickback (IEC 61000-4-4 EFT). Use Value: Absorbs 600 W pulses without degradation, ensuring >100,000 surge cycles and eliminating need for external series impedance in basic input protection. |
| Telecom Line Interface | Consumer Appliance Motor Control |
Use Scenario: Shielding RS-485 transceivers and Ethernet PHYs in network edge devices from induced surges on long cable runs. IC Role / Device Role / Timing Role: Differential-mode TVS pair (one per line) referenced to common ground, providing symmetrical clamping for balanced signaling. Use Value: Matches differential impedance while clamping common-mode transients to <17 V, preserving data integrity under IEC 61000-4-5 2 kV surge tests. | Use Scenario: Suppressing commutation spikes from brushed DC motors in smart home appliances (e.g., vacuum cleaners, washing machines). IC Role / Device Role / Timing Role: Across-the-line TVS mounted directly at motor terminals to clamp back-EMF spikes before reaching MCU GPIOs or driver ICs. Use Value: Withstands repetitive 100 A peak surge currents (IFSM-equivalent energy), extending system reliability without requiring snubber RC networks. |
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, 400 W PPPM, higher VC (17.0 V @ 35.3 A), lower VBR min (11.1 V) | Lower surge rating limits use in high-energy automotive transients; suitable for consumer-grade 24 V systems | Select SMAJ10CA where cost sensitivity outweighs peak power requirement and layout space is constrained. |
| 1.5KE10CA | Through-hole DO-201 package, 1500 W PPPM, same VWM/VBR, larger footprint and higher inductance | Not suitable for automated SMT; preferred for prototyping or legacy through-hole designs needing higher energy handling | Choose 1.5KE10CA only when board real estate allows DO-201 and surge requirements exceed 600 W. |
Compared with SMAJ10CA and 1.5KE10CA, the SM6T10CA-E3/52 offers optimal balance of SMT manufacturability, 600 W surge capability, and low-profile SMB packaging - making it preferred for high-volume automotive and industrial PCBs where reflow compatibility and consistent clamping performance are critical.

FAQ
What is the polarity configuration of the SM6T10CA-E3/52?
The SM6T10CA-E3/52 is a bidirectional TVS diode with symmetrical avalanche characteristics in both directions. It has no cathode band or polarity marking, allowing flexible placement across AC-coupled or differential signal paths without orientation constraints. This configuration ensures identical clamping behavior regardless of voltage polarity applied across its terminals, unlike unidirectional variants such as SM6T10A.
Does the SM6T10CA-E3/52 meet AEC-Q101 qualification?
The SM6T10CA-E3/52 itself is RoHS-compliant commercial-grade (E3 suffix), not AEC-Q101 qualified. However, Vishay offers AEC-Q101 variants under ordering codes SM6T10CAHE3_X (HE3 suffix), which share identical electrical specs and SMB packaging but undergo additional automotive stress testing. Always verify the full part number suffix when selecting for automotive applications.
What is the maximum clamping voltage of the SM6T10CA-E3/52 under standard test conditions?
The SM6T10CA-E3/52 has a maximum clamping voltage (VC) of 16.7 V when subjected to a 10/1000 μs waveform at its rated peak pulse current of 36 A. This value is measured per Figure 1 in the Vishay datasheet 88385 and represents the upper limit of voltage seen by protected circuitry during worst-case surge events.
Can the SM6T10CA-E3/52 be used in place of a unidirectional TVS like SM6T10A?
No - the SM6T10CA-E3/52 is strictly bidirectional and cannot replace unidirectional TVS diodes like SM6T10A in DC-biased circuits requiring forward conduction blocking. Substituting it in such applications would allow unintended reverse current flow. Use SM6T10CA-E3/52 only where symmetrical clamping is required, such as AC lines, differential buses, or floating grounds.
What PCB pad layout is recommended for optimal thermal and surge performance of the SM6T10CA-E3/52?
Vishay specifies a minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad area per terminal for the SM6T10CA-E3/52 to achieve rated 600 W peak pulse power and proper thermal dissipation. Smaller pads reduce surge capability and increase junction temperature; adherence to the recommended layout ensures compliance with IEC 61000-4-5 Level 4 testing requirements.
