Product details
Overview
SMCJ60-E3/9AT from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 60 V stand-off voltage (VWM), 66.7–73.7 V breakdown range (VBR), 96.8 V clamping voltage (VC) at 15.5 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive ECUs, industrial PLC I/O modules, and telecom power supplies.
For engineers reviewing the SMCJ60-E3/9AT datasheet, SMCJ60-E3/9AT pinout, SMCJ60-E3/9AT application, or SMCJ60-E3/9AT equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, RoHS-compliant matte tin plating, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 µA leakage at 60 V), then rapidly avalanches when transient voltage exceeds VBR, clamping the line to ≤96.8 V while diverting up to 15.5 A (10/1000 µs). Its glass-passivated junction ensures stable breakdown and low incremental surge resistance.
Thermal performance is defined by RθJA = 75 °C/W (on recommended pad layout) and RθJL = 15 °C/W, enabling reliable operation from –55 °C to +150 °C junction temperature. The device meets UL 497B recognition (QVGQ2) and complies with ANSI/IEEE C62.35 surge standards.

IC Role / Device Role / Timing Role: Bidirectional protection not applicable; SMCJ60-E3/9AT used unidirectionally across loop supply and return. Use Value: Withstands repetitive 1 kV/500 A surges (IEC 61000-4-5) while maintaining <1 µA leakage at 60 V operating point. |
| Telecom DC Power Input Protection | Motor Drive Control Signal Protection |
Use Scenario: Guarding -48 V DC telecom rectifier outputs against lightning-induced surges on primary distribution lines. IC Role / Device Role / Timing Role: Unidirectional TVS connected anode-to-ground, cathode-to-rail, absorbing negative-going transients.

IC Role / Device Role / Timing Role: Low-capacitance (<100 pF) unidirectional clamp on logic-level control lines referenced to floating ground. Use Value: Prevents false triggering or latch-up in level-shifters and optocouplers during dV/dt events up to 100 V/ns. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60A-E3/52T | Lower PPPM (600 W), smaller SMB package (DO-214AA), same VWM/VC specs | Suitable for space-constrained consumer or non-automotive industrial designs with lower surge exposure | Select when board area is critical and peak surge energy does not exceed 600 W |
| SMCJ60AHE3/9AT | Identical electrical specs but AEC-Q101 qualified; HE3 suffix denotes automotive-grade screening | Required for automotive OEM designs where component-level qualification is mandated | Choose SMCJ60AHE3/9AT for production vehicles; SMCJ60-E3/9AT suffices for aftermarket or industrial use |
Compared with SMBJ60A-E3/52T, SMCJ60-E3/9AT delivers 2.5× higher surge power handling in a larger footprint; versus SMCJ60AHE3/9AT, it offers identical protection performance without automotive qualification overhead - ideal for cost-sensitive industrial power systems.

FAQ
What is the clamping voltage of SMCJ60-E3/9AT and how is it measured?
The clamping voltage (VC) of SMCJ60-E3/9AT is 96.8 V, measured at a peak pulse current (IPPM) of 15.5 A using a standardized 10/1000 µs double-exponential waveform. This value reflects the maximum voltage seen across the device during surge conduction and is critical for ensuring downstream components remain within their absolute maximum ratings. SMCJ60-E3/9AT achieves this clamping performance while dissipating 1500 W peak power.
Is SMCJ60-E3/9AT suitable for automotive applications?
SMCJ60-E3/9AT is RoHS-compliant and manufactured to commercial-grade specifications. While it shares the same DO-214AB package and electrical characteristics as the AEC-Q101-qualified SMCJ60AHE3/9AT, the E3 suffix indicates it is not formally qualified to AEC-Q101. For production automotive systems requiring qualification, SMCJ60AHE3/9AT is required; SMCJ60-E3/9AT remains appropriate for aftermarket, industrial, or telecom applications where AEC-Q101 is not mandated.
What is the thermal resistance of SMCJ60-E3/9AT and how does it affect PCB layout?
SMCJ60-E3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the minimum recommended 8.0 mm × 8.0 mm copper pads per terminal. This value assumes no additional heatsinking; exceeding 150 °C junction temperature risks parametric shift or failure. To maintain reliability under repeated surges, designers must allocate sufficient copper area and avoid routing heat-sensitive components nearby. SMCJ60-E3/9AT's RθJL of 15 °C/W further emphasizes the importance of solid thermal connection to PCB planes.
How does the unidirectional configuration of SMCJ60-E3/9AT impact circuit placement?
SMCJ60-E3/9AT is unidirectional, meaning it blocks voltage in one direction and clamps in reverse. The cathode (marked by a band) must be connected to the line being protected (e.g., +60 V rail), while the anode connects to ground or the lower-potential reference. Incorrect orientation results in forward conduction during normal operation - causing excessive leakage, overheating, and potential failure. Always verify polarity during layout and assembly; bi-directional variants (e.g., SMCJ60CA) lack the band and protect both polarities.
What packaging format does SMCJ60-E3/9AT ship in and what are its handling implications?
SMCJ60-E3/9AT ships in 13-inch plastic tape-and-reel format (package code 9AT), with 3500 units per reel. As a moisture-sensitive device rated MSL Level 1 (J-STD-020), it requires no dry-pack or baking prior to SMT reflow - peak temperature up to 260 °C is permitted. The matte tin-plated leads ensure compatibility with lead-free soldering processes and pass JESD 201 Class 1A whisker testing, making SMCJ60-E3/9AT suitable for high-volume automated assembly without special handling protocols.
