Product details
Overview
1.5SMC13A-E3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 13 V breakdown voltage (VBR min/max = 12.4–13.7 V at 1.0 mA), 11.1 V stand-off voltage (VWM), clamps to ≤18.2 V at 82.4 A peak pulse current (10/1000 µs), and delivers 1500 W peak pulse power. It is used to protect MOSFETs, ICs, and sensor interfaces against lightning-induced surges and inductive switching transients in automotive and industrial control systems.
For engineers reviewing the 1.5SMC13A-E3/57T datasheet, 1.5SMC13A-E3/57T pinout, 1.5SMC13A-E3/57T application, or 1.5SMC13A-E3/57T equivalent, key selection criteria include its unidirectional polarity, SMC (DO-214AB) package compatibility, 1500 W surge rating, low clamping ratio (VC/VBR ≈ 1.4), and AEC-Q101 qualification eligibility via HE3 suffix variants.
Technical Context
This TVS diode operates as a clamping device that remains high-impedance below VWM (11.1 V) and rapidly avalanches above VBR (12.4–13.7 V) to limit transient voltages. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the low incremental surge resistance supports effective energy diversion during 10/1000 µs transients.
The device is rated for 150 °C maximum junction temperature, exhibits a +0.081 %/°C VBR temperature coefficient, and is qualified per J-STD-020 MSL Level 1 (260 °C reflow peak). Its thermal resistance (RθJA = 75 °C/W) assumes mounting on 8.0 mm × 8.0 mm copper pads - critical for sustaining repetitive surge duty cycles up to 0.01 %.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A-E3/52 | Lower peak power (600 W), smaller SMB (DO-214AA) package, same VWM/VBR range | Not suitable for IEC 61000-4-5 Level 4; limited to lower-energy surges in space-constrained consumer designs | Select when board area is critical and surge threat level is ≤1 kV; verify thermal derating for repetitive events |
| 1.5KE13A | Through-hole DO-201AE package, identical electrical specs but higher RθJA (100 °C/W), no MSL rating | Requires wave soldering; unsuitable for mixed-technology or high-volume SMT lines | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with SMBJ13A-E3/52 and 1.5KE13A, the 1.5SMC13A-E3/57T provides superior surge robustness (1500 W vs. 600 W or 1500 W with inferior thermal management), standardized SMT manufacturability, and MSL Level 1 compliance - making it the preferred choice for production-grade automotive and industrial power rail protection.

FAQ
What is the maximum clamping voltage of the 1.5SMC13A-E3/57T under a 10/1000 µs surge?
The 1.5SMC13A-E3/57T clamps to a maximum of 18.2 V when subjected to its rated peak pulse current of 82.4 A with a 10/1000 µs waveform. This value is measured at the device terminals under standardized test conditions (TA = 25 °C, mounted on 8.0 mm × 8.0 mm copper pads) and defines the upper voltage limit imposed on protected circuits during surge events. The 1.5SMC13A-E3/57T maintains this clamping performance consistently due to its glass-passivated junction and low dynamic impedance.
Is the 1.5SMC13A-E3/57T RoHS-compliant and halogen-free?
Yes, the 1.5SMC13A-E3/57T carries the "E3" suffix, indicating it is RoHS-compliant and manufactured to commercial-grade specifications per Vishay's material categorization standards. It is not halogen-free; for halogen-free compliance, the "M3" variant (e.g., 1.5SMC13A-M3/57T) must be selected. Both E3 and M3 versions meet JESD 201 Class 2 whisker resistance and J-STD-020 MSL Level 1 reflow requirements. The 1.5SMC13A-E3/57T is fully traceable and documented in Vishay's compliance portal.
Does the 1.5SMC13A-E3/57T have AEC-Q101 qualification?
The base 1.5SMC13A-E3/57T is not AEC-Q101 qualified; however, Vishay offers AEC-Q101-qualified versions under the HE3 and HM3 suffixes (e.g., 1.5SMC13AHE3_A). These variants undergo extended stress testing including temperature cycling, HTRB, and ESD per AEC-Q101 Rev D and are designated for automotive applications. The 1.5SMC13A-E3/57T itself is rated for operation from –65 °C to +150 °C and meets MSL Level 1, but formal automotive qualification requires the HE3/HM3 part number.
What is the thermal resistance of the 1.5SMC13A-E3/57T, and how does it affect layout?
The 1.5SMC13A-E3/57T 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 - as specified in the Vishay datasheet. This value assumes optimal PCB copper area; reducing pad size increases RθJA, risking thermal runaway during repetitive surges. For reliable operation, maintain minimum pad dimensions and consider internal copper planes for enhanced heat spreading. The 1.5SMC13A-E3/57T's RθJL is 15 °C/W, supporting efficient conduction to PCB traces.
How does the 1.5SMC13A-E3/57T differ from bidirectional TVS diodes like 1.5SMC13CA?
The 1.5SMC13A-E3/57T is unidirectional and functions only in reverse bias - conducting surge current from cathode to anode during overvoltage events - whereas the 1.5SMC13CA is bidirectional and protects both polarities symmetrically. Unidirectional types offer lower leakage at VWM and tighter VBR tolerance, making the 1.5SMC13A-E3/57T ideal for DC power rails with defined polarity. Bidirectional variants are reserved for AC lines or floating signals where polarity reversal may occur. The 1.5SMC13A-E3/57T's cathode band must be oriented toward the protected line's positive side.
