Product details
Overview
SMCJ130-E3/57T from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for robust overvoltage protection of sensitive electronics. It features a 130 V standoff voltage (VWM), 144–159 V breakdown range (VBR at 1 mA), 209 V clamping voltage (VC) at 7.2 A peak pulse current, and 1500 W peak pulse power dissipation with 10/1000 µs waveform - deployed in automotive power rails, industrial I/O interfaces, and DC-DC converter input stages.
For engineers reviewing the SMCJ130-E3/57T datasheet, SMCJ130-E3/57T pinout, SMCJ130-E3/57T application, or SMCJ130-E3/57T equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, RoHS-compliant matte tin plating, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ130-E3/57T operates as a silicon avalanche diode that enters breakdown when reverse voltage exceeds its VBR threshold (144–159 V), clamping transients to ≤209 V within picoseconds. Its low incremental surge resistance and fast response time enable effective suppression of ESD, lightning-induced surges, and inductive switching spikes.
Thermally, it exhibits RθJA = 75 °C/W and RθJL = 15 °C/W, supporting reliable operation up to 150 °C junction temperature. The device is rated for 200 A non-repetitive forward surge current (8.3 ms half-sine) and meets J-STD-020 MSL Level 1 with 260 °C reflow peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before conduction begins |
| VBR (min/max) | 144 V / 159 V at 1 mA - Confirmed breakdown range defining turn-on threshold tolerance |
| VC @ IPPM | 209 V at 7.2 A - Clamped voltage during 10/1000 µs surge, limiting stress on downstream circuitry |

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 package (DO-214AA), same VWM/VC ratings | Suitable for space-constrained consumer or computing designs where 1500 W surge capacity is not required | Select when board area is limited and peak surge energy is <600 W |
| SMCJ130AHE3/57T | Identical electrical specs but AEC-Q101 qualified version (HE3 suffix); same DO-214AB package and marking code GHK | Required for automotive OEM designs requiring full automotive qualification documentation and traceability | Choose for automotive production programs needing AEC-Q101 compliance evidence |
Compared with SMCJ130-E3/57T, SMBJ130A-E3/52T trades surge capacity for footprint reduction, while SMCJ130AHE3/57T adds formal AEC-Q101 validation without altering performance - making the original ideal for cost-sensitive industrial applications requiring 1500 W clamping without full automotive certification overhead.

FAQ
What is the clamping voltage of the SMCJ130-E3/57T under maximum surge conditions?
The SMCJ130-E3/57T has a maximum clamping voltage (VC) of 209 V at 7.2 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The SMCJ130-E3/57T maintains this clamping performance across its specified operating temperature range.
Is the SMCJ130-E3/57T suitable for automotive applications?
The SMCJ130-E3/57T is RoHS-compliant and manufactured in an AEC-Q101-qualified process flow (per Vishay documentation), though the E3 suffix denotes commercial-grade qualification. For full AEC-Q101-certified parts, Vishay offers SMCJ130AHE3/57T. The SMCJ130-E3/57T remains widely used in non-safety-critical automotive subsystems where its 150 °C TJ max and robust surge handling meet functional requirements.
What does the "E3/57T" suffix indicate in SMCJ130-E3/57T?
The "E3" suffix indicates RoHS-compliant matte tin plating and JESD201 Class 1A whisker resistance; "57T" specifies packaging in 7-inch plastic tape-and-reel format with 850 units per reel. This ordering code ensures compatibility with standard SMT pick-and-place equipment and supports high-volume automated assembly. The SMCJ130-E3/57T uses DO-214AB (SMCJ) mechanical outline per Vishay's package drawings.
How does the SMCJ130-E3/57T differ from bi-directional variants like SMCJ130CA?
The SMCJ130-E3/57T is unidirectional, meaning it conducts only during reverse-bias overvoltage events and blocks forward current - ideal for DC power line protection. In contrast, SMCJ130CA is bi-directional, providing symmetrical clamping for AC or floating signal lines. The SMCJ130-E3/57T features a cathode band marking; SMCJ130CA has no polarity marking and identical VBR in both directions.
What thermal derating applies to the SMCJ130-E3/57T above 25 °C ambient?
The SMCJ130-E3/57T follows Vishay's standard derating curve (Fig. 2): peak pulse power (PPPM) decreases linearly above 25 °C ambient, reaching ~50% at 125 °C. Its RθJA = 75 °C/W assumes mounting on 8.0 mm × 8.0 mm copper pads per terminal. For sustained power dissipation, the 6.5 W rating at TA = 50 °C must also be observed. The SMCJ130-E3/57T remains fully functional up to 150 °C junction temperature.
