Product details
Overview
SM15T10CA-M3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, rated for 1500 W peak pulse power (10/1000 μs), 10 V stand-off voltage (VWM), and clamping voltage of 17.0 V at 87.5 A peak pulse current. It protects signal and power lines in automotive sensor interfaces and industrial I/O modules against lightning-induced and switching transients.
For engineers reviewing the SM15T10CA-M3/57T datasheet, SM15T10CA-M3/57T pinout, SM15T10CA-M3/57T application, or SM15T10CA-M3/57T equivalent, key selection criteria include bidirectional clamping capability, 10 V VWM, 17.0 V VC at IPPM, halogen-free RoHS compliance (M3 suffix), and SMC package thermal performance with RθJA = 75 °C/W.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering consistent clamping behavior during positive and negative transients without polarity-dependent biasing. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<10 μA at VWM) over temperature.
The device is optimized for high-impedance source environments-such as sensor signal lines and CAN bus stubs-where system-level source impedance naturally limits surge current to within its 87.5 A IPPM rating under 10/1000 μs waveform conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 12 V nominal systems. |
| VBR min / max | 11.4 V / 12.6 V at 1.0 mA - Confirmed breakdown threshold range ensures reliable turn-on without premature conduction. |
| VC @ IPPM | 17.0 V at 87.5 A (10/1000 μs) - Clamping voltage directly limits transient energy delivered to downstream ICs like microcontrollers or transceivers. |
| PPPM | 1500 W - Peak pulse power handling capacity validated for lightning surge (IEC 61000-4-5 Level 4) and inductive switch-off events. |
| TJ max | +150 °C - Enables operation in under-hood automotive and industrial control cabinet environments without derating. |
| Package | SMC (DO-214AB) - Standardized surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height; compatible with automated pick-and-place. |
Pinout & Package
SM15T10CA-M3/57T uses a 2-terminal SMC (DO-214AB) package with no polarity marking-consistent with bidirectional functionality. Terminals are matte tin-plated and solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional transient conduction path | Either terminal serves as anode or cathode depending on transient polarity; no orientation required during PCB placement. |
| Case (body) | Thermal and mechanical interface | Plastic-molded body meets UL 94 V-0; copper pad layout (8.0 mm × 8.0 mm per terminal) required to sustain 1500 W pulse rating. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or differential lines (e.g., RS-485, CAN FD) without external polarity management. |
| 1500 W peak pulse power (10/1000 μs) | Validated for IEC 61000-4-5 combination wave (2 Ω/12 Ω source) up to Level 4 (4 kV line-earth), supporting robust front-end surge immunity. |
| Halogen-free, RoHS-compliant (M3 suffix) | Meets IPC-1752A material declaration requirements and JESD201 Class 2 whisker resistance for long-term reliability in harsh environments. |
| Low clamping ratio (VC/VBR ≈ 1.35) | Minimizes voltage overshoot during clamping-critical for protecting 3.3 V or 5 V logic interfaces downstream of protected lines. |
Applications
| Automotive Sensor Protection | Industrial I/O Module Protection |
|---|---|
Use Scenario: Protecting LIN bus and analog sensor outputs (e.g., pressure, temperature) in engine control units exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed between sensor output and ECU input to shunt transients before reaching ADC or comparator inputs. Use Value: Prevents latch-up or permanent damage to 5 V tolerant microcontroller GPIOs while maintaining signal integrity below 17.0 V during 10/1000 μs surges. |
Use Scenario: Safeguarding 24 V digital input channels in PLC backplanes against field-wiring induced transients from solenoid de-energization. IC Role / Device Role / Timing Role: Front-end transient suppressor on each isolated input channel, mounted directly at connector entry point. Use Value: Limits transient voltage to ≤17.0 V at 87.5 A, ensuring optocoupler input diodes and series current-limiting resistors remain within SOA during repeated 1 kV/0.5 J events. |
| Telecom Line Interface Protection | Consumer Appliance Motor Control |
Use Scenario: Shielding RS-485 transceiver pins in building automation gateways connected to long outdoor cabling susceptible to induced lightning surges. IC Role / Device Role / Timing Role: Differential-line TVS placed across A/B bus terminals to clamp common-mode and differential-mode transients simultaneously. Use Value: Symmetrical 11.4–12.6 V breakdown and 17.0 V clamping ensure balanced suppression without skewing differential signaling margins. |
Use Scenario: Guarding MCU reset and communication lines in smart washing machine control boards near brushless motor drivers. IC Role / Device Role / Timing Role: Localized TVS on 3.3 V supply rail and UART lines adjacent to motor driver IC to absorb coupling from PWM edge-induced noise. Use Value: 10 V VWM provides 3 V headroom above 3.3 V rail while 17.0 V clamping prevents overvoltage stress on 5 V tolerant peripherals. |
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 | Lower PPPM (400 W), same VWM/VC, SMA package (smaller thermal mass, higher RθJA = 110 °C/W) | Suitable only for lower-energy threats (IEC 61000-4-2 ESD, not full lightning surge) | Select when board space is constrained and surge threat level is limited to ±8 kV contact ESD or <100 W transients. |
| 1.5KE10CA | Higher VC (18.2 V), axial lead DO-201 package, same 1500 W rating but slower response due to higher parasitic inductance | Requires through-hole mounting; less suitable for high-speed signal lines or automated SMT assembly | Choose for legacy designs requiring axial components or where PCB layout allows larger footprint and higher inductance is acceptable. |
Compared with SMAJ10CA and 1.5KE10CA, SM15T10CA-M3/57T delivers identical 10 V standoff and superior thermal performance in SMT form factor-enabling higher sustained surge duty cycles in space-constrained automotive and industrial modules without compromising clamping precision.

FAQ
What is the peak pulse current rating of SM15T10CA-M3/57T under standard test conditions?
The SM15T10CA-M3/57T has a peak pulse current (IPPM) of 87.5 A when tested with a 10/1000 μs waveform at TA = 25 °C on specified copper pads. This value is derived from its 1500 W peak pulse power rating and 17.0 V clamping voltage (IPPM = PPPM/VC). The SM15T10CA-M3/57T maintains this rating only when mounted per the recommended 8.0 mm × 8.0 mm pad layout.
Does SM15T10CA-M3/57T meet automotive qualification standards?
The SM15T10CA-M3/57T itself is commercial-grade with halogen-free RoHS compliance (M3 suffix); however, the SM15T family includes AEC-Q101 qualified variants under ordering codes ending in HE3 or HM3. For automotive use, SM15T10CAHM3_A/H is the qualified version-SM15T10CA-M3/57T is not AEC-Q101 certified but shares identical electrical and thermal specs.
How does the bidirectional design of SM15T10CA-M3/57T affect PCB layout?
The SM15T10CA-M3/57T has no polarity marking and functions identically regardless of orientation, simplifying PCB layout and eliminating risk of reverse installation. This symmetry allows direct placement across differential pairs (e.g., RS-485 A/B) or AC signal paths without directional routing constraints-unlike unidirectional TVS diodes that require strict cathode/anode alignment.
What is the maximum junction-to-ambient thermal resistance for SM15T10CA-M3/57T?
The typical thermal resistance from junction to ambient (RθJA) for SM15T10CA-M3/57T is 75 °C/W when mounted on the recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. This value assumes still air convection and is critical for calculating junction temperature rise during repetitive surge events-SM15T10CA-M3/57T must stay below +150 °C TJ max.
Can SM15T10CA-M3/57T be used to protect a 3.3 V logic line?
Yes, SM15T10CA-M3/57T can protect a 3.3 V logic line if placed upstream of level-shifting circuitry or behind a current-limiting resistor, because its 10 V stand-off voltage (VWM) prevents conduction during normal operation. However, its 17.0 V clamping voltage means it must not be placed directly on the 3.3 V rail-SM15T10CA-M3/57T is intended for higher-voltage interfaces (e.g., 12 V sensor supplies, 24 V I/O) where clamping headroom is sufficient.
