Product details
Overview
SMCJ6.0CHE3/57T 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 SMCJ6.0CHE3/57T datasheet, SMCJ6.0CHE3/57T pinout, SMCJ6.0CHE3/57T application, or SMCJ6.0CHE3/57T 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
This TVS diode operates as a voltage-clamping device in series with power or signal lines, conducting only when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable leakage (<1000 µA at VWM) and fast response (<1 ns), while low incremental surge resistance enables effective energy diversion during transients like ISO 7637-2 pulses.
The SMCJ6.0CHE3/57T is rated for continuous operation from –55 °C to +150 °C junction temperature and supports automated SMT placement. Its 0.31" × 0.31" copper pad layout meets JEDEC mounting requirements and delivers specified PPPM derating above TA = 25 °C per Figure 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum reverse working voltage before clamping begins; defines safe operating margin below breakdown |
| VBR min/max | 6.67 V / 7.37 V at 10 mA - Confirmed breakdown range ensures reliable turn-on across process variation |
| VC @ IPPM | ≤10.3 V at 145.6 A - Clamping voltage under full 1500 W surge; critical for downstream IC survivability |
| PPPM | 1500 W (10/1000 µs) - Peak transient energy handling capacity; validates compliance with IEC 61000-4-5 Level 4 |
| ID @ VWM | ≤1000 µA - Low leakage preserves system efficiency and prevents false triggering in high-impedance circuits |
| TJ max | +150 °C - Enables use in under-hood automotive environments without derating penalties |
| RθJA | 75 °C/W - Thermal resistance with recommended 8.0 mm × 8.0 mm copper pads; determines board-level thermal design margin |
Pinout & Package

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump and alternator transients per ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground, clamping surges before they reach DC-DC converters and microcontrollers. Use Value: With 1500 W PPPM and ≤10.3 V clamping, SMCJ6.0CHE3/57T limits voltage seen by downstream 5 V/3.3 V logic to safe levels during 120 V/50 ms transients. | Use Scenario: Safeguarding analog sensor outputs (e.g., pressure, temperature) connected to MCU ADC inputs in factory automation systems. IC Role / Device Role / Timing Role: TVS mounted at connector entry point, shunting ESD (IEC 61000-4-2 ±8 kV contact) and cable discharge events away from precision front-end circuitry. Use Value: Sub-1000 µA leakage at 6.0 V VWM avoids signal offset errors, while 145.6 A IPPM handles multi-kV fast transients without degradation. |
| Telecom Line Interface Protection | Consumer Power Adapter Input Protection |
Use Scenario: Shielding RS-485 transceivers and PHYs on base station backhaul links from lightning-induced surges on long-distance twisted-pair lines. IC Role / Device Role / Timing Role: Bidirectional-capable variant not applicable; this unidirectional part used on DC bias rails feeding isolated data lines. Use Value: 75 °C/W RθJA allows direct PCB mounting near connectors without heatsinks, supporting compact telecom module designs meeting GR-1089-CORE. | Use Scenario: Adding secondary overvoltage protection on the primary-side DC bus of USB-C PD adapters after bridge rectification. IC Role / Device Role / Timing Role: Clamping device placed across bulk capacitor to absorb switching spikes and line surges exceeding MOV capability. Use Value: 6.0 V VWM aligns with 5–7 V DC bus ranges; 10.3 V VC ensures MOSFETs and controllers remain within absolute maximum ratings during 1.2/50 µs ringwave events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A-E3/61 | Lower PPPM (400 W), smaller SMA package (DO-214AC), higher RθJA (110 °C/W) | Suitable for space-constrained consumer boards with lower surge exposure (IEC 61000-4-4 Level 3) | Select when board area is limited and surge threat level is moderate; verify thermal margin with reduced copper area |
| 1.5KE6.8A | Through-hole TO-218 package, same 1500 W rating but slower response (>5 ns), no AEC-Q101 qualification | Used in legacy industrial power supplies where automated SMT is not required | Choose for cost-sensitive, non-automotive applications where leaded assembly remains viable and AEC-Q101 is not mandated |
Compared with SMAJ6.0A-E3/61 and 1.5KE6.8A, the SMCJ6.0CHE3/57T uniquely combines AEC-Q101 qualification, 1500 W SMT capability, and 75 °C/W thermal resistance-making it the preferred choice for new automotive and high-reliability industrial designs requiring validated surge immunity and production scalability.

FAQ
What is the clamping voltage of the SMCJ6.0CHE3/57T under full-rated surge current?
The SMCJ6.0CHE3/57T clamps to a maximum of 10.3 V when subjected to its rated peak pulse current of 145.6 A (10/1000 µs waveform). This value is measured per ANSI/IEEE C62.35 and confirmed in the Vishay datasheet Document Number 88394, page 2. The low clamping voltage ensures protected downstream components such as 5 V microcontrollers remain within their absolute maximum voltage ratings during transient events.
Is the SMCJ6.0CHE3/57T suitable for automotive applications?
Yes, the SMCJ6.0CHE3/57T is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet (Document Number 88394, page 1 and page 3). Its qualification covers temperature cycling, high-temperature reverse bias, and ESD testing, making it suitable for under-hood and body-control module applications. The HE3 suffix specifically denotes AEC-Q101 compliance and JESD 201 Class 2 whisker resistance.
What does the "HE3/57T" suffix indicate in SMCJ6.0CHE3/57T?
The "HE3" suffix indicates RoHS-compliant, AEC-Q101 qualified construction with JESD 201 Class 2 whisker resistance; "57T" specifies packaging in 7-inch diameter plastic tape and reel, with a base quantity of 850 units. This ordering code appears in the Vishay "Ordering Information" table (page 3 of Document Number 88394) and confirms full traceability and production-grade packaging for automated assembly.
How does the thermal performance of SMCJ6.0CHE3/57T compare to smaller package alternatives?
The SMCJ6.0CHE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads-significantly lower than SMAJ-series parts (e.g., SMAJ6.0A-E3/61 at 110 °C/W). This 32 % improvement in thermal efficiency allows higher sustained power dissipation and reduces risk of thermal runaway during repeated surge events, especially in enclosed automotive enclosures.
Can SMCJ6.0CHE3/57T be used in bidirectional protection circuits?
No, the SMCJ6.0CHE3/57T is a unidirectional TVS diode, as confirmed by its "A" suffix (per Vishay's naming convention: "A" = unidirectional, "CA" = bidirectional). Its cathode band marking and forward voltage specification (VF = 3.5 V at 100 A) confirm asymmetric conduction. For bidirectional protection, select an SMCJ6.0CA variant instead-using SMCJ6.0CHE3/57T in bidirectional configurations risks failure during positive-going transients.
