Product details
Overview
1.5SMC10A-M3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection. It features 10 V standoff voltage (VWM), 14.5 V clamping voltage (VC) at 103 A peak pulse current, and 1500 W peak pulse power capability with 10/1000 μs waveform - ideal for safeguarding power rails and I/O lines in automotive and industrial control modules.
For engineers reviewing the 1.5SMC10A-M3/57T datasheet, 1.5SMC10A-M3/57T pinout, 1.5SMC10A-M3/57T application, or 1.5SMC10A-M3/57T equivalent, key selection criteria include clamping performance under 103 A surge, thermal resistance (RθJA = 75 °C/W), halogen-free RoHS compliance (M3 suffix), and AEC-Q101 qualification readiness via HM3 variants.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging glass-passivated junction technology for stable breakdown behavior and low incremental surge resistance. Its 10 V stand-off voltage ensures compatibility with 9–12 V nominal supply rails, while 14.5 V clamping limits transient overvoltage to safe levels for downstream MOSFETs and microcontrollers.
The 1.5SMC10A-M3/57T delivers fast response time (<1 ns) and meets MSL level 1 per J-STD-020 with 260 °C reflow peak. It is rated for -65 °C to +150 °C operating junction temperature and supports repetitive surge duty cycles up to 0.01 %, making it suitable for cyclic load-switching environments like automotive body electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 8.55 V - maximum reverse voltage before conduction; sets minimum system operating margin for 9 V rails |
| VBR (Breakdown Voltage) | 9.50–10.5 V at 1 mA - precise threshold where avalanche conduction begins |
| VC (Clamping Voltage) | 14.5 V at 103 A IPPM - limits transient voltage seen by protected ICs during 10/1000 μs surges |
| PPPM (Peak Pulse Power) | 1500 W - energy-handling capacity for standardized lightning/surge transients |
| RθJA (Junction-to-Ambient) | 75 °C/W - defines thermal derating on standard 8 mm × 8 mm copper pads |
| IPPM (Peak Pulse Current) | 103 A - maximum non-repetitive surge current supported under 10/1000 μs waveform |
| TJ max. | +150 °C - enables operation in under-hood automotive environments without thermal shutdown |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant (M3 suffix), matte tin-plated leads solderable per J-STD-002.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A-E3/52 | Lower PPPM (600 W), same VWM/VC, SMB package (smaller footprint, higher RθJA) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 | Select when board space is constrained and surge threat level is ≤ Level 2 |
| 1.5KE10A | Through-hole DO-201 package, identical electrical specs but no M3 halogen-free option | Requires wave soldering; incompatible with fully SMT production flow | Choose only for legacy through-hole designs or prototyping with breadboard adapters |
Compared with SMBJ10A-E3/52 and 1.5KE10A, the 1.5SMC10A-M3/57T uniquely combines 1500 W surge rating, SMC surface-mount compatibility, halogen-free compliance, and AEC-Q101 qualification path - making it the optimal choice for high-reliability automotive and industrial SMT production.

FAQ
What is the clamping voltage of the 1.5SMC10A-M3/57T under maximum surge conditions?
The 1.5SMC10A-M3/57T has a maximum clamping voltage (VC) of 14.5 V at 103 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per standard test conditions (TA = 25 °C, mounted on 8 mm × 8 mm copper pads) and defines the upper voltage limit imposed on protected circuitry during worst-case transients. The 1.5SMC10A-M3/57T maintains this clamping performance across its qualified operating temperature range.
Is the 1.5SMC10A-M3/57T suitable for automotive applications?
Yes - the 1.5SMC10A-M3/57T is halogen-free and RoHS-compliant (M3 suffix), and belongs to the AEC-Q101-qualified 1.5SMC family. While the base 1.5SMC10A-M3/57T itself carries commercial-grade qualification, Vishay offers the HM3 variant (e.g., 1.5SMC10AHM3_A/H) with full AEC-Q101 certification. Engineers using the 1.5SMC10A-M3/57T in automotive designs should verify qualification status per ordering code and consult Vishay's automotive-grade documentation for the 1.5SMC10A-M3/57T.
How does the 1.5SMC10A-M3/57T differ from bidirectional TVS diodes like 1.5SMC10CA?
The 1.5SMC10A-M3/57T is unidirectional and features a cathode band for polarity identification, enabling use in DC circuits where reverse voltage blocking is required. In contrast, 1.5SMC10CA is bidirectional with symmetrical clamping in both directions and no polarity marking. The 1.5SMC10A-M3/57T exhibits lower leakage at VWM (10 μA vs. 20 μA for 10CA) and is optimized for single-polarity rail protection, whereas 1.5SMC10CA suits AC-coupled or differential signal lines. Both share identical VWM, VC, and PPPM ratings.
What is the thermal resistance and how does it affect PCB layout for the 1.5SMC10A-M3/57T?
The 1.5SMC10A-M3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. This value assumes minimum recommended pad layout per Vishay's datasheet. To maintain safe junction temperatures under sustained power dissipation or repeated surges, designers must provide adequate copper area and avoid excessive trace length or isolation. The 1.5SMC10A-M3/57T's RθJA directly impacts derating above 25 °C ambient, per Figure 2 in the official datasheet.
Can the 1.5SMC10A-M3/57T be used in parallel for higher surge current handling?
No - the 1.5SMC10A-M3/57T is not characterized or recommended for parallel operation. Variations in breakdown voltage (VBR tolerance: 9.50–10.5 V) cause uneven current sharing during surges, risking thermal runaway in the unit with lower VBR. Vishay specifies single-device operation only. For higher surge ratings, select a higher-power TVS (e.g., 3.0SMC10A) or implement staged protection with upstream current-limiting elements. The 1.5SMC10A-M3/57T datasheet does not validate parallel configurations.
