Product details
Overview
SMCJ6.0HE3/57T 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 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 1500 W peak pulse power (10/1000 µs), 145.6 A peak pulse current (IPPM), and clamps to ≤10.3 V at rated surge. It is AEC-Q101 qualified and used in automotive power line and sensor interface protection.
For engineers reviewing the SMCJ6.0HE3/57T datasheet, SMCJ6.0HE3/57T pinout, SMCJ6.0HE3/57T application, or SMCJ6.0HE3/57T equivalent, key selection criteria include unidirectional polarity, 1500 W surge rating, 10.3 V clamping voltage at IPPM, RoHS-compliant AEC-Q101 qualification, and DO-214AB thermal performance with RθJA = 75 °C/W.
Technical Context
The SMCJ6.0HE3/57T operates as a silicon avalanche diode, responding to transients within picoseconds via reverse-biased junction breakdown. Its glass-passivated chip junction ensures stable VBR tolerance and low leakage (<1000 µA at VWM), while the DO-214AB package supports automated placement and meets UL 94 V-0 flammability.
It is rated for -55 °C to +150 °C operating junction temperature, derates linearly above 25 °C per Fig. 2, and delivers 1500 W peak pulse power only when mounted on 8.0 mm × 8.0 mm copper pads per JEDEC standard test conditions. The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.

Applications
| Automotive Power Line Protection | Industrial Sensor Interface |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and ground, clamping surges before they reach DC-DC converters or microcontrollers. Use Value: Limits voltage to ≤10.3 V during 145.6 A transients, preventing latch-up or gate oxide damage in downstream ICs. |
Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance TVS on signal lines, positioned adjacent to connector entry point. Use Value: Sub-1000 µA leakage at 6.0 V preserves millivolt-level signal accuracy; fast response avoids data corruption. |
| Telecom DC Power Input | Consumer Device USB Port |
Use Scenario: Safeguarding PoE-powered equipment inputs against induced lightning surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 48 V input rail, upstream of primary DC-DC stage. Use Value: 1500 W rating handles 10/1000 µs surges per IEC 61000-4-5; 150 °C TJ max supports sealed enclosure thermal design. |
Use Scenario: ESD protection for USB 2.0 VBUS line in portable devices. IC Role / Device Role / Timing Role: Standoff-rated TVS absorbing ±8 kV contact ESD per IEC 61000-4-2 without crowbarring. Use Value: 6.0 V VWM allows full 5.5 V USB specification margin; 10.3 V VC prevents brownout during ESD event. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A-E3/57T | Lower PPPM (400 W), smaller SMA package (DO-214AC), higher RθJA (110 °C/W) | Suitable for space-constrained consumer boards but insufficient for automotive load dump | Select only where surge energy ≤400 W and thermal budget permits higher junction rise |
| 1.5KE6.8A | Through-hole TO-218 package, same VWM (6.8 V), higher VC (11.5 V), identical 1500 W rating | Requires PCB through-hole real estate and wave-solder process; not AEC-Q101 qualified | Choose for legacy industrial designs needing proven reliability but no automotive qualification |
Compared with SMAJ6.0A-E3/57T and 1.5KE6.8A, the SMCJ6.0HE3/57T uniquely combines AEC-Q101 qualification, surface-mount DO-214AB packaging, and 1500 W surge capability-enabling automotive-grade protection without through-hole assembly or derated power handling.

FAQ
What is the clamping voltage of the SMCJ6.0HE3/57T under maximum rated surge current?
The SMCJ6.0HE3/57T clamps to a maximum of 10.3 V when subjected to its rated 145.6 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and verified at TA = 25 °C with specified PCB pad layout. The SMCJ6.0HE3/57T maintains this clamping performance across its qualified operating temperature range.
Is the SMCJ6.0HE3/57T suitable for bi-directional transient protection?
No, the SMCJ6.0HE3/57T is a unidirectional TVS diode, as confirmed by its "A" suffix and cathode band marking. For bi-directional protection, Vishay specifies the SMCJ6.0CA variant. Using the SMCJ6.0HE3/57T in reverse-biased AC applications risks permanent failure due to forward conduction during negative transients. The SMCJ6.0HE3/57T must be oriented with cathode toward the protected line.
Does the HE3 suffix on SMCJ6.0HE3/57T indicate AEC-Q101 qualification?
Yes, the HE3 suffix explicitly denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance per Vishay's ordering nomenclature. This distinguishes it from the commercial-grade E3 suffix (e.g., SMCJ6.0A-E3/57T). The SMCJ6.0HE3/57T has undergone full stress testing per AEC-Q101 Rev D, including HTGB, HTRB, and temperature cycling, making it suitable for automotive under-hood applications.
What is the maximum reverse leakage current of the SMCJ6.0HE3/57T at its rated stand-off voltage?
The SMCJ6.0HE3/57T exhibits a maximum reverse leakage current (ID) of 1000 µA at its 6.0 V stand-off voltage (VWM), tested at TA = 25 °C. This low leakage ensures minimal impact on power rail efficiency and signal integrity in always-on systems. The SMCJ6.0HE3/57T maintains leakage below 1000 µA up to TJ = 125 °C per characterization curves in the datasheet.
Can the SMCJ6.0HE3/57T be used in place of the SMCJ6.0A-E3/57T without design changes?
Yes, the SMCJ6.0HE3/57T is footprint- and functionally compatible with SMCJ6.0A-E3/57T-same DO-214AB package, identical electrical specs, and shared marking code GDG. The only difference is the HE3 suffix confirming AEC-Q101 qualification and enhanced whisker resistance. No PCB layout or schematic change is needed to upgrade to the SMCJ6.0HE3/57T for automotive or high-reliability use.
