Product details
Overview
SMCJ130A-E3/57T from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 130 V standoff voltage (VWM), 144–159 V breakdown voltage (VBR) at 1 mA, 209 V maximum clamping voltage (VC) at 7.2 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the SMCJ130A-E3/57T datasheet, SMCJ130A-E3/57T pinout, SMCJ130A-E3/57T application, or SMCJ130A-E3/57T equivalent, this device is selected for high-energy surge immunity in automotive power modules, industrial motor drives, and telecom interface protection where fast response (<1 ns), low clamping ratio (1.61×VWM), and AEC-Q101-compliant reliability are required.
Technical Context
The SMCJ130A-E3/57T operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology to achieve stable reverse breakdown and low incremental surge resistance. Its clamping behavior is defined under standardized 10/1000 µs surge conditions, with thermal resistance RθJA = 75 °C/W and RθJL = 15 °C/W enabling effective heat dissipation on standard PCB copper pads.
It complies with ANSI/IEEE C62.35 for surge protector classification and meets UL 497B recognition (QVGQ2, E136766). The device is RoHS-compliant (E3 suffix), rated for -55 °C to +150 °C operating junction temperature, and qualified to MSL level 1 per J-STD-020 with 260 °C reflow peak.
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 |
|---|---|---|---|
| SMBJ130A-E3/52T | Lower PPPM (600 W), smaller SMB (DO-214AA) package, same VWM/VC specs. | Suitable for space-constrained consumer electronics; insufficient for automotive load dump. | Select when board area is critical and surge energy is ≤600 W. |
| 1.5KE130A | Through-hole DO-201 package, higher VC (219 V), identical electrical ratings otherwise. | Used in legacy industrial power supplies where SMT is not feasible; requires wave soldering. | Choose for repair/refurbishment of through-hole designs or prototyping with breadboard compatibility. |
Compared with SMCJ130A-E3/57T, SMBJ130A-E3/52T offers footprint reduction at the cost of 60 % lower surge capacity, while 1.5KE130A retains full electrical performance but sacrifices SMT manufacturability and thermal performance due to higher RθJA.

FAQ
What is the maximum clamping voltage of the SMCJ130A-E3/57T under standard test conditions?
The SMCJ130A-E3/57T has a maximum clamping voltage (VC) of 209 V when subjected to a 10/1000 µs surge waveform at 7.2 A peak pulse current. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's datasheet revision 09-Jan-2024 (Document Number: 88394). The clamping voltage directly limits stress on downstream components, making it a critical parameter for validating protection margin in 130 V systems.
Is the SMCJ130A-E3/57T suitable for automotive applications requiring AEC-Q101 qualification?
No - the SMCJ130A-E3/57T uses the E3 suffix, indicating RoHS-compliant commercial grade only. For AEC-Q101 qualification, the correct part is SMCJ130AHE3_A/H or SMCJ130AHM3_A/H (HE3/HM3 suffixes). The SMCJ130A-E3/57T lacks the automotive qualification testing and traceability required for under-hood or safety-critical vehicle systems, though it shares identical electrical characteristics and package with its qualified variants.
What is the thermal resistance from junction to ambient for the SMCJ130A-E3/57T?
The typical thermal resistance from junction to ambient (RθJA) for the SMCJ130A-E3/57T is 75 °C/W, measured with the device mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. This value assumes standard JEDEC test conditions and is essential for calculating safe operating temperature rise under continuous power dissipation (PD = 6.5 W at TA = 50 °C). Derating curves in Figure 2 of the datasheet must be applied for ambient temperatures above 25 °C.
How does the SMCJ130A-E3/57T differ from bidirectional variants like SMCJ130CA?
The SMCJ130A-E3/57T is unidirectional, with polarity marked by a cathode band and intended for DC line protection where reverse conduction is not required. In contrast, SMCJ130CA is bidirectional, has no polarity marking, and clamps symmetrically in both directions - making it suitable for AC signal lines or differential buses. Both share identical VWM, VBR, and PPPM, but the SMCJ130A-E3/57T exhibits forward voltage drop (~3.5 V at 100 A), whereas the CA version does not conduct forward under normal bias.
What is the minimum recommended PCB pad layout for optimal surge handling of the SMCJ130A-E3/57T?
Vishay specifies a minimum pad layout of 0.31" × 0.31" (8.0 mm × 8.0 mm) copper areas per terminal for the SMCJ130A-E3/57T to achieve rated 1500 W peak pulse power. Smaller pads increase thermal impedance and reduce surge current capability. The SMC (DO-214AB) outline drawing on page 5 confirms land pattern dimensions, and adherence to this layout is required to meet the 7.2 A IPPM and 209 V VC specifications under 10/1000 µs testing.
