Product details
Overview
SMCJ100A-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 up to 162 V at 9.3 A peak pulse current (10/1000 µs), with 100 V standoff voltage and 1500 W peak pulse power rating. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power supply rails.
For engineers reviewing the SMCJ100A-E3/57T datasheet, SMCJ100A-E3/57T pinout, SMCJ100A-E3/57T application, or SMCJ100A-E3/57T equivalent, key selection criteria include its 100 V reverse standoff voltage, 111–123 V breakdown range at 1 mA, 162 V clamping voltage under 9.3 A surge, 1.0 µA max leakage at VWM, and AEC-Q101 qualification eligibility via HE3 suffix variants.
Technical Context
The SMCJ100A-E3/57T operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology for stable breakdown and low incremental surge resistance. Its clamping behavior follows IEEE C62.35 standards, with thermal resistance of 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-lead).
Designed for transient suppression on DC power lines and signal paths, it responds within picoseconds to ESD and inductive switching events. The device is rated for -55 °C to +150 °C operating junction temperature and meets J-STD-020 MSL Level 1 reflow profile (260 °C peak).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VWM) | 100 V - Maximum continuous reverse operating voltage before significant conduction begins. |
| Breakdown Voltage (VBR) | 111–123 V at 1 mA - Confirmed avalanche initiation range; ensures reliable triggering above normal operating rail. |
| Clamping Voltage (VC) | 162 V at 9.3 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case surge; defines protection margin. |
| Peak Pulse Power (PPPM) | 1500 W - Sustains high-energy transients without failure when mounted per recommended 8 mm × 8 mm copper pads. |
| Leakage Current (ID) | ≤1.0 µA at 100 V - Negligible standby power loss and minimal impact on high-impedance sensing circuits. |
| Junction Temperature Range | -55 °C to +150 °C - Supports under-hood automotive and industrial environments without derating below 25 °C. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, matte tin-plated leads, RoHS-compliant (E3 suffix), UL 94 V-0 molding compound. Cathode indicated by band; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when VLINE exceeds VBR. |
| Anode (unbanded end) | Reference / ground return | Typically tied to system ground or low-impedance return path; completes clamping loop during overvoltage event. |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SMC package | Enables automated placement in space-constrained PCB layouts while maintaining 1500 W surge capability. |
| Glass-passivated junction | Ensures stable VBR tolerance and long-term reliability under repeated surge stress and humidity exposure. |
| Very fast response time | Sub-nanosecond clamping onset protects sensitive gate oxides and logic inputs from ESD and inductive kick. |
| MSL Level 1 compliance | Supports standard lead-free reflow (260 °C peak) without preconditioning or dry-pack requirements. |
| AEC-Q101 qualification path | E3 suffix enables drop-in upgrade to HE3 variant for automotive applications requiring stress-tested TVS devices. |
Applications
| Automotive Power Rail Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: 12 V/24 V battery-fed ECUs exposed to load dump (ISO 7637-2 Pulse 5a) and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp surges before they reach PMICs and microcontrollers. Use Value: Withstands 1500 W pulses and clamps to ≤162 V, preserving downstream components rated for ≤180 V absolute maximum. |
Use Scenario: Digital input modules receiving 24 V DC signals from field sensors in factory automation systems. IC Role / Device Role / Timing Role: Standoff-rated TVS on each input channel suppresses inductive switching noise from solenoids and contactors. Use Value: 1.0 µA leakage at 100 V avoids false triggering in high-impedance optocoupler interfaces; 162 V clamping prevents latch-up in 3.3 V logic buffers. |
| DC-DC Converter Input Stage | Motor Drive Gate Driver Protection |
Use Scenario: 48 V input stage of isolated buck converter in telecom power supplies subject to lightning-induced surges. IC Role / Device Role / Timing Role: Primary transient shunt on bulk capacitor input, coordinated with upstream fuse and common-mode choke. Use Value: 111–123 V VBR provides 13–23 V headroom above nominal 100 V max input, enabling robust margin against overshoot. |
Use Scenario: High-side N-channel MOSFET gate driver circuits in BLDC inverters where Miller spikes threaten gate oxide integrity. IC Role / Device Role / Timing Role: TVS across gate-source terminals limits dV/dt-induced turn-on and clamps gate voltage to safe levels. Use Value: Sub-nanosecond response and 162 V clamping protect 20 V-rated gate drivers without adding RC snubbers or slowing switching. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100A-E3/57T | Lower PPPM (400 W), same VWM/VBR/VC, SMA package (smaller footprint, lower thermal mass). | Suitable for lower-energy transients; not recommended for ISO 7637-2 Pulse 5a or high-current inductive loads. | Select when board space is critical and surge energy remains below 400 W; verify thermal derating at elevated ambient. |
| SMCJ100CA-E3/57T | Bidirectional version; identical VWM/VBR/VC ratings but symmetric clamping in both polarities. | Required for AC-coupled or floating signal lines (e.g., RS-485, CAN bus) where polarity reversal occurs. | Choose only if bidirectional protection is needed; unidirectional SMCJ100A-E3/57T offers lower leakage and simpler grounding in DC rails. |
Compared with SMAJ100A-E3/57T, the SMCJ100A-E3/57T delivers 3.75× higher surge power handling and superior thermal dissipation; versus SMCJ100CA-E3/57T, it provides tighter leakage control and optimized unidirectional clamping for grounded DC systems.

FAQ
What is the clamping voltage of the SMCJ100A-E3/57T under a 10/1000 µs surge?
The SMCJ100A-E3/57T clamps to a maximum of 162 V when subjected to a 9.3 A peak pulse current with a 10/1000 µs waveform. This value is measured under standardized test conditions with the device mounted on 8.0 mm × 8.0 mm copper pads per terminal, ensuring repeatable thermal performance and accurate system-level protection modeling for the SMCJ100A-E3/57T.
Is the SMCJ100A-E3/57T RoHS-compliant and halogen-free?
Yes, the SMCJ100A-E3/57T carries the E3 suffix, indicating full RoHS compliance per EU Directive 2011/65/EU. It is not halogen-free; for halogen-free and RoHS-compliant versions, specify the M3 suffix (e.g., SMCJ100A-M3/57T). Both E3 and M3 meet JESD201 Class 2 whisker resistance requirements.
Does the SMCJ100A-E3/57T have AEC-Q101 qualification?
The base SMCJ100A-E3/57T is not AEC-Q101 qualified; however, Vishay offers the SMCJ100AHE3_X variant (e.g., SMCJ100AHE3_A) which adds AEC-Q101 qualification while retaining identical electrical specs and SMC package. The "HE3" ordering code denotes RoHS-compliant + AEC-Q101 qualified versions of the SMCJ100A-E3/57T family.
What is the thermal resistance of the SMCJ100A-E3/57T?
The SMCJ100A-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead resistance (RθJL) of 15 °C/W, measured under standard JEDEC conditions. These values assume mounting on minimum recommended pad layout (0.31″ × 0.31″ copper per terminal); actual RθJA improves with larger copper areas or internal layer heatsinking for the SMCJ100A-E3/57T.
How does the SMCJ100A-E3/57T differ from the SMCJ100CA-E3/57T?
The SMCJ100A-E3/57T is unidirectional (cathode-banded), while the SMCJ100CA-E3/57T is bidirectional with no polarity marking. Both share identical VWM (100 V), VBR (111–123 V), VC (162 V), and PPPM (1500 W), but the CA version conducts in both directions-making it suitable for AC or floating lines. The SMCJ100A-E3/57T offers lower leakage (1.0 µA vs. 2.0 µA for CA at VWM) in DC-grounded applications.
