Product details
Overview
SMCJ60-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 60 V stand-off voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 96.8 V maximum clamping voltage (VC) at 15.5 A peak pulse current (IPPM), and 1500 W peak pulse power dissipation (PPPM) under 10/1000 µs waveform - deployed in automotive power line and industrial sensor interface protection.
For engineers reviewing the SMCJ60-E3/57T datasheet, SMCJ60-E3/57T pinout, SMCJ60-E3/57T application, or SMCJ60-E3/57T equivalent, key selection criteria include clamping performance at rated surge current, unidirectional polarity marking, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), and RoHS-compliant matte tin plating per J-STD-002.
Technical Context
The SMCJ60-E3/57T operates as a silicon avalanche diode with glass-passivated junction, delivering fast response time (<1 ns) to transient events such as inductive load switching or ESD. Its unidirectional configuration uses a cathode band marking and exhibits forward conduction only during reverse overvoltage events - not intended for DC forward bias operation.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads per terminal, it supports automated placement and meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow peak. Thermal derating begins above TA = 25 °C, with maximum junction temperature limited to +150 °C and storage range from –55 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Applications
| Automotive Power Line Protection | Industrial Sensor Interface |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump (ISO 16750-2) and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp surges >60 V. Use Value: Limits peak voltage to ≤96.8 V at 15.5 A, preventing damage to MCU power supplies and CAN transceivers. | Use Scenario: Shielding analog output lines (e.g., 4–20 mA current loop) from ESD and field-induced spikes. IC Role / Device Role / Timing Role: Bidirectional protection is not used; SMCJ60-E3/57T serves as unidirectional clamp on supply side of sensor front-end. Use Value: Sub-µA leakage avoids loading precision current sources, while 1500 W PPPM handles multi-kV ESD events. |
| Telecom DC Power Input | Computer Peripheral Port Protection |
Use Scenario: Safeguarding PoE-powered devices (e.g., IP cameras) against induced surges on 48 V DC input rails. IC Role / Device Role / Timing Role: Mounted upstream of DC-DC converter input to absorb line-to-ground transients. Use Value: Clamps 48 V nominal rail to <100 V during 10/1000 µs surges, preserving converter IC integrity without derating. | Use Scenario: Protecting USB or HDMI hot-swap connectors from human-body-model (HBM) ESD events. IC Role / Device Role / Timing Role: Placed on VBUS line to shunt ESD current away from USB controller IC. Use Value: 96.8 V clamping voltage prevents latch-up in 5 V tolerant I/O cells while maintaining <1 µA standby leakage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60A-E3/52T | Lower PPPM (400 W), smaller DO-214AC (SMA) package, same VWM/VBR/VC specs | Not suitable for 1500 W surge environments; limited to lower-energy transients | Select when board space is constrained and surge threat level is ≤400 W (e.g., consumer USB ports) |
| SMCJ60AHE3/57T | Identical electrical specs but AEC-Q101 qualified (HE3 suffix); same DO-214AB package | Required for automotive OEM designs requiring full qualification evidence | Choose for Tier-1 automotive programs where AEC-Q101 documentation and traceability are mandatory |
Compared with SMAJ60A-E3/52T and SMCJ60AHE3/57T, the SMCJ60-E3/57T offers the full 1500 W surge rating in a standard commercial-grade DO-214AB package - balancing cost, performance, and manufacturability for industrial and telecom applications where AEC-Q101 is not mandated.

FAQ
What is the clamping voltage of the SMCJ60-E3/57T and how is it measured?
The SMCJ60-E3/57T has a maximum clamping voltage (VC) of 96.8 V, measured at a peak pulse current (IPPM) of 15.5 A using a 10/1000 µs double-exponential waveform. This value represents the highest voltage seen across the device terminals during standardized surge testing and is critical for ensuring downstream components remain within their absolute maximum ratings. The SMCJ60-E3/57T achieves this clamping performance due to its low incremental surge resistance and optimized silicon junction design.
Is the SMCJ60-E3/57T suitable for automotive applications?
The SMCJ60-E3/57T is RoHS-compliant and manufactured in an AEC-Q101-qualified facility, but the E3 suffix denotes commercial-grade qualification - not full AEC-Q101 certification. For automotive use, the SMCJ60AHE3/57T variant (HE3 suffix) must be selected, as it carries formal AEC-Q101 test reports and traceability. The SMCJ60-E3/57T remains appropriate for non-safety-critical industrial or telecom systems where full automotive qualification is not required.
How does the SMCJ60-E3/57T differ from bi-directional TVS diodes like SMCJ60CA?
The SMCJ60-E3/57T is unidirectional and features a cathode band marking, conducting only during reverse overvoltage events - it blocks forward current beyond ~3.5 V. In contrast, SMCJ60CA is bi-directional with no polarity marking and clamps symmetrically in both directions. The SMCJ60-E3/57T is preferred for DC power rail protection where polarity is fixed, offering tighter leakage control (1.0 µA vs. 1000 µA for CA types at lower VWM), while SMCJ60CA suits AC-coupled or floating signal lines.
What is the thermal resistance and how does it affect PCB layout for the SMCJ60-E3/57T?
The SMCJ60-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on minimum recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. To maintain safe junction temperatures under repetitive surge conditions or elevated ambient, designers must allocate sufficient copper area and consider thermal vias. Reducing RθJA below 75 °C/W requires larger pads or internal ground planes - critical for applications with frequent transients or high ambient temperatures.
Does the SMCJ60-E3/57T require derating at elevated ambient temperatures?
Yes, the SMCJ60-E3/57T must be derated above TA = 25 °C per Figure 2 in the Vishay datasheet (Document Number: 88394). Its peak pulse power (PPPM) decreases linearly with rising ambient temperature - for example, at TA = 100 °C, only ~50% of the 1500 W rating remains usable. Derating ensures the junction temperature stays within the +150 °C maximum limit. Designers should consult the derating curve and apply appropriate safety margins based on expected operating conditions and surge repetition rate.
