Product details
Overview
SMCJ100-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 100 V stand-off voltage (VWM), 111–123 V breakdown range (VBR), 162 V clamping voltage (VC) at 9.3 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 µs waveform - ideal for safeguarding power rails and signal lines in automotive ECUs and industrial motor drives.
For engineers reviewing the SMCJ100-E3/57T datasheet, SMCJ100-E3/57T pinout, SMCJ100-E3/57T application, or SMCJ100-E3/57T equivalent, key selection criteria include clamping performance under 10/1000 µs surge, thermal resistance (RθJA = 75 °C/W), AEC-Q101 qualification status, RoHS compliance (E3 suffix), and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ100-E3/57T operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology for stable breakdown behavior and low incremental surge resistance. Its clamping action begins at VBR (111–123 V) and limits transient voltages to ≤162 V at rated IPPM, ensuring downstream ICs remain within safe operating limits during ESD or load-dump events.
Designed for surface-mount use in DO-214AB, it supports high-reliability applications with MSL Level 1 moisture sensitivity, JESD201 Class 1A whisker resistance, and operation across –55 °C to +150 °C junction temperature range - validated per AEC-Q101 for automotive-grade deployment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - maximum continuous reverse working voltage before clamping initiates |
| VBR min/max | 111 V / 123 V at 1 mA test current - defines reliable avalanche onset window |
| VC @ IPPM | 162 V at 9.3 A - peak clamped voltage during 10/1000 µs surge, limiting stress on protected circuitry |
| PPPM | 1500 W - peak transient energy absorption capability under standardized waveform |
| RθJA | 75 °C/W - thermal resistance from junction to ambient, critical for derating above 25 °C |
| TJ max | +150 °C - maximum allowable junction temperature for sustained reliability |

Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable, repeatable breakdown characteristics and long-term reliability under repeated surges |
| Low incremental surge resistance | Minimizes voltage overshoot during fast transients, improving clamping precision |

| RoHS-compliant (E3 suffix) | Meets EU Directive 2011/65/EU for hazardous substance restrictions |
Applications
| Automotive Power Rail Protection | Industrial Motor Drive Control |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-fed microcontroller power inputs against ISO 7637-2 load-dump transients up to 120 V. IC Role / Device Role / Timing Role: Unidirectional TVS placed between rail and ground to clamp surges before they reach LDOs or MCU VDD pins. Use Value: Clamps to ≤162 V at 9.3 A, preventing latch-up or permanent damage to 5 V logic supplies downstream. | Use Scenario: Safeguarding gate driver IC inputs from inductive kickback during IGBT switching in variable-frequency drives. IC Role / Device Role / Timing Role: Placed across isolated gate drive transformer secondary to suppress reflected spikes. Use Value: Fast response time and low clamping voltage preserve gate oxide integrity and prevent false turn-on. |
| Telecom Line Interface Protection | Consumer Power Adapter Output Stage |
Use Scenario: Shielding RS-485 transceiver bus lines from lightning-induced surges in outdoor base stations. IC Role / Device Role / Timing Role: Bi-directional variant used (e.g., SMCJ100CA), but SMCJ100-E3/57T serves as unidirectional alternative where polarity is controlled. Use Value: 1500 W PPPM rating handles multi-kV induced transients while maintaining signal integrity via low capacitance. | Use Scenario: Secondary-side overvoltage suppression in 12 V wall adapters subjected to AC line surges or capacitor discharge events. IC Role / Device Role / Timing Role: Connected between DC output and ground to absorb energy from failed feedback loop or rectifier failure. Use Value: 100 V VWM aligns with typical 12 V adapter output tolerances; 162 V VC prevents downstream regulator overvoltage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ100A | Same DO-214AC (SMA) package; 100 V VWM, 160 V VC @ 9.4 A; RθJA = 85 °C/W | Slightly higher thermal resistance; not AEC-Q101 qualified | Select for cost-sensitive industrial designs where automotive qualification is unnecessary |
| ON Semiconductor 1.5SMC100A | DO-214AB package; identical 100 V VWM, 162 V VC @ 9.3 A; same AEC-Q101 and RoHS status | Same footprint and electrical specs; alternate sourcing option with comparable supply chain | Preferred for dual-sourcing strategies requiring identical form, fit, and function |
Compared with SMCJ100-E3/57T, SMAJ100A offers lower cost but lacks automotive qualification and has reduced thermal performance, while 1.5SMC100A provides full drop-in equivalence including AEC-Q101, making it suitable for seamless second-source deployment.

FAQ
What is the clamping voltage of the SMCJ100-E3/57T under a 10/1000 µs surge?
The SMCJ100-E3/57T clamps to a maximum of 162 V when subjected to its rated 9.3 A peak pulse current (IPPM) under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 standards and ensures protected circuits remain below destructive voltage thresholds during transient events.
Is the SMCJ100-E3/57T suitable for automotive applications?
Yes, the SMCJ100-E3/57T is AEC-Q101 qualified and rated for operation from –55 °C to +150 °C, making it suitable for under-hood and chassis-mounted automotive electronics. Its MSL Level 1 rating and JESD201 Class 1A whisker resistance further validate its suitability for automotive production environments.
What does the "E3/57T" suffix indicate in SMCJ100-E3/57T?
The "E3" suffix denotes RoHS-compliant construction and JESD201 Class 1A whisker resistance; "57T" specifies packaging in 7-inch diameter plastic tape and reel, with a base quantity of 850 units per reel - optimized for high-volume SMT assembly lines.
How does the SMCJ100-E3/57T differ from bi-directional variants like SMCJ100CA?
The SMCJ100-E3/57T is unidirectional, with cathode marked by a band and intended for DC rail protection where polarity is fixed. In contrast, SMCJ100CA is bi-directional, unmarked, and suited for AC or floating signal lines - both share identical VWM, VBR, and PPPM ratings but differ in conduction symmetry and marking.
What PCB layout guidance applies to the SMCJ100-E3/57T for optimal thermal performance?
For optimal thermal performance, mount the SMCJ100-E3/57T on minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, as specified in the Vishay datasheet. This pad area enables effective heat dissipation and supports the rated 1500 W PPPM without exceeding the 75 °C/W RθJA limit under defined test conditions.
