Product details
Overview
SMCJ13A-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 13 V standoff voltage (VWM), 21.5 V maximum clamping voltage (VC) at 69.8 A peak pulse current (IPPM), and 1500 W peak pulse power (10/1000 µs waveform), suitable for protecting MOSFETs, ICs, and sensor interfaces in automotive and industrial power rails.
For engineers reviewing the SMCJ13A-E3/57T datasheet, SMCJ13A-E3/57T pinout, SMCJ13A-E3/57T application, or SMCJ13A-E3/57T equivalent, key selection criteria include its 14.4–15.9 V breakdown range (VBR), low 1.0 µA reverse leakage at VWM, ±0.084 %/°C temperature coefficient of VBR, and AEC-Q101 qualification readiness via HE3 suffix variants.
Technical Context
The SMCJ13A-E3/57T operates as a unidirectional avalanche diode with glass-passivated junction, delivering fast response to transient overvoltages while maintaining stable clamping performance across -55 °C to +150 °C junction temperature range. Its low incremental surge resistance enables consistent energy absorption under repetitive 10/1000 µs surges up to 1500 W.
Designed for automated SMT placement, it meets J-STD-020 MSL Level 1 (peak reflow 260 °C), uses matte tin-plated leads compliant with J-STD-002 and JESD22-B102, and carries RoHS-compliant E3 suffix marking. Polarity is indicated by cathode band; no marking on bidirectional versions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 13 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (Breakdown Voltage) | 14.4–15.9 V at 1.0 mA test current - Ensures reliable avalanche initiation within defined tolerance |
| VC (Clamping Voltage) | 21.5 V at 69.8 A IPPM - Limits downstream voltage stress during 10/1000 µs transients |
| IPPM (Peak Pulse Current) | 69.8 A - Sustains single-event surge without degradation under standard waveform |
| PPPM (Peak Pulse Power) | 1500 W - Energy-handling capacity for transient suppression per IEEE C62.35 |
| TJmax | +150 °C - Enables operation in under-hood automotive and high-temperature industrial environments |
| Leakage (ID) | ≤1.0 µA at VWM - Minimizes standby power loss in always-on circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC13A-TB-E3/57T | Same VWM (13 V), but lower PPPM (600 W); smaller SMA package (DO-214AC) | Limited to lower-energy transients; unsuitable for automotive load-dump duty cycles | Select when board space is constrained and surge energy does not exceed 600 W |
| SMCJ13CA-E3/57T | Bidirectional version; identical VWM, VC, and PPPM, but symmetric clamping in both polarities | Required for AC-coupled or floating signal lines where negative transients occur | Choose for RS-485, CAN, or audio lines needing protection against bipolar surges |
Compared with SAC13A-TB-E3/57T, the SMCJ13A-E3/57T offers 2.5× higher surge power handling and superior thermal dissipation in SMC package; versus SMCJ13CA-E3/57T, it provides optimized unidirectional clamping with tighter leakage control for DC power rails.

FAQ
What is the breakdown voltage range of the SMCJ13A-E3/57T?
The SMCJ13A-E3/57T has a guaranteed breakdown voltage (VBR) range of 14.4 V to 15.9 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This ensures predictable avalanche onset across manufacturing lots and temperature extremes, critical for consistent clamping behavior in the SMCJ13A-E3/57T.
Is the SMCJ13A-E3/57T RoHS-compliant and halogen-free?
Yes, the SMCJ13A-E3/57T carries the E3 suffix, indicating RoHS-compliance per EU Directive 2011/65/EU. It is not halogen-free; for halogen-free compliance, the M3 suffix variant (e.g., SMCJ13A-M3/57T) must be selected. Both meet JESD201 Class 2 whisker resistance requirements.
Can the SMCJ13A-E3/57T be used in automotive applications?
The SMCJ13A-E3/57T is commercial-grade; however, Vishay offers AEC-Q101 qualified versions under HE3/HM3 suffixes (e.g., SMCJ13AHE3_A/H). For production automotive use, the SMCJ13A-E3/57T requires validation per vehicle-level requirements, whereas the HE3 variant is pre-qualified for under-hood and chassis applications.
What is the thermal resistance of the SMCJ13A-E3/57T?
The SMCJ13A-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" copper pads per JEDEC standards. Its junction-to-lead resistance (RθJL) is 15 °C/W, supporting effective heat transfer to PCB copper in high-power transient events involving the SMCJ13A-E3/57T.
How does the clamping voltage of SMCJ13A-E3/57T compare to its standoff voltage?
The SMCJ13A-E3/57T clamps at 21.5 V (VC) under 69.8 A peak pulse current, representing a clamping ratio of ~1.65× its 13 V standoff voltage (VWM). This ratio reflects low incremental resistance during conduction and ensures protected circuitry remains below critical overvoltage thresholds during transients affecting the SMCJ13A-E3/57T.
