Product details
Overview
1.5SMC10A-E3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on power and signal lines. It features a 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage at 103 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - ideal for protecting MOSFETs and ICs in automotive and industrial power supplies.
For engineers reviewing the 1.5SMC10A-E3/57T datasheet, 1.5SMC10A-E3/57T pinout, 1.5SMC10A-E3/57T application, or 1.5SMC10A-E3/57T equivalent, this part delivers verified transient suppression performance with AEC-Q101 qualification options, RoHS-compliant matte tin plating, and MSL Level 1 moisture sensitivity - critical for high-reliability board-level ESD and surge protection design.
Technical Context
The 1.5SMC10A-E3/57T operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its 9.5–10.5 V breakdown range (IT = 1 mA). Its low incremental surge resistance and fast response time ensure effective clamping of lightning-induced surges and inductive switching spikes before downstream components are damaged.
Thermally, it sustains 150 °C maximum junction temperature with RθJA = 75 °C/W and RθJL = 15 °C/W, and is rated for 200 A non-repetitive forward surge (8.3 ms half-sine) - enabling robust protection in 12 V and 24 V DC systems where transient energy exceeds standard TVS capabilities.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 8.55 V - maximum continuous reverse operating voltage before clamping begins; defines safe operating margin below breakdown |
| VBR (Breakdown) | 9.5–10.5 V at 1 mA - precise avalanche threshold ensuring predictable turn-on during overvoltage events |
| VC (Clamping) | 14.5 V at 103 A IPPM - limits voltage seen by protected circuit under worst-case 1500 W transient |
| PPPM | 1500 W - peak pulse power handling with 10/1000 µs waveform, supporting IEC 61000-4-5 Level 4 surge immunity |
| IPPM | 103 A - peak pulse current capability directly determines survivability against 1 kV/500 A surge waveforms |
| Leakage (ID) | 10 µA max at 8.55 V - negligible standby power loss and no interference with low-current sensor or logic circuits |
| TJ max | 150 °C - enables operation in under-hood automotive environments and enclosed industrial enclosures |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, low-profile case with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102. Polarity indicated by cathode band; unidirectional configuration only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., GND or return path); carries surge current during clamping |
| Cathode | Avalanche clamping terminal | Connected to protected line (e.g., 12 V rail); initiates conduction when reverse voltage exceeds VWM |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power | Enables compliance with IEC 61000-4-5 surge test requirements up to Level 4 (4 kV line-earth, 2 kV line-line) |
| Glass passivated junction | Ensures stable breakdown voltage and long-term reliability under thermal cycling and humidity stress |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow without preconditioning; eliminates moisture-related popcorning risk |
| AEC-Q101 qualified option | Validated for automotive powertrain and body electronics applications requiring zero defect field performance |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage exposure to protected ICs - critical for 3.3 V or 5 V logic interfacing with 12 V domains |
Applications
| Automotive Power Distribution | Industrial PLC I/O Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | Same VWM (8.55 V), lower PPPM (600 W), SMB package (smaller footprint, higher RθJA = 85 °C/W) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 or automotive load dump | Select when board space is constrained and surge threat level is limited to IEC 61000-4-2 ESD or low-duty-cycle switching noise. |
| 1.5KE10A | Through-hole TO-204AA (DO-41), identical electrical specs but incompatible mounting and thermal profile (RθJA = 100 °C/W) | Requires PCB redesign; not suitable for automated SMT assembly or high-density layouts | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required. |
Compared with SMBJ10A and 1.5KE10A, the 1.5SMC10A-E3/57T uniquely balances high-power transient handling (1500 W), SMT manufacturability, and automotive-grade reliability - making it the preferred choice for new production designs targeting IPC-A-610 Class 3 or ISO/TS 16949 compliance.

FAQ
What is the maximum clamping voltage of the 1.5SMC10A-E3/57T under full-rated surge conditions?
The 1.5SMC10A-E3/57T has a maximum clamping voltage (VC) of 14.5 V when subjected to its rated 103 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is guaranteed per Vishay's datasheet Document Number 88303 and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The 1.5SMC10A-E3/57T maintains this clamping performance across its full operating temperature range of –65 °C to +150 °C.
Is the 1.5SMC10A-E3/57T RoHS-compliant and lead-free?
Yes, the 1.5SMC10A-E3/57T carries the "E3" suffix, indicating full RoHS compliance and lead-free construction per EU Directive 2011/65/EU. Its matte tin-plated terminals meet J-STD-002 solderability standards and JESD 22-B102 whisker testing (Class 2). The 1.5SMC10A-E3/57T is also halogen-free and complies with Vishay's material categorization per document 99912.
Does the 1.5SMC10A-E3/57T have AEC-Q101 qualification?
The base 1.5SMC10A-E3/57T is commercial-grade and not AEC-Q101 qualified; however, the automotive-grade variant 1.5SMC10AHE3_A/E3/57T (with HE3 suffix) is fully AEC-Q101 qualified for automotive applications. That version undergoes additional stress testing including temperature cycling, HTRB, and ESD per AEC-Q101 Rev D. The 1.5SMC10A-E3/57T itself shares identical electrical and thermal specs but lacks the automotive qualification documentation.
What is the thermal resistance of the 1.5SMC10A-E3/57T, and how does it affect layout?
The 1.5SMC10A-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-leads resistance (RθJL) of 15 °C/W, measured on 0.31″ × 0.31″ (8.0 mm × 8.0 mm) copper pads per terminal. To maintain safe junction temperatures under repeated surges, PCB layout must provide adequate copper area and thermal vias - reducing RθJA below 50 °C/W is recommended for high-duty-cycle applications. The 1.5SMC10A-E3/57T's low RθJL supports efficient heat transfer to the PCB substrate.
Can the 1.5SMC10A-E3/57T be used in bidirectional configurations?
No, the 1.5SMC10A-E3/57T is strictly unidirectional, as confirmed by its part number suffix "A" and cathode band marking. For bidirectional operation, Vishay specifies the "CA" suffix (e.g., 1.5SMC10CA). Using the 1.5SMC10A-E3/57T in reverse-biased configurations risks permanent damage due to lack of symmetrical avalanche structure. Always verify polarity during placement - the cathode band must face the protected line.
