Product details
Overview
SMCJ6.0CA-TR from STMicroelectronics is a bidirectional 6.0 V transient voltage suppression (TVS) diode in SMC package, designed for high-energy ESD and surge protection in DC power rails and signal lines. It delivers 1500 W peak pulse power (10/1000 µs), clamps to 10.3 V at 152 A, and maintains ≤0.2 µA leakage at 25 °C - enabling robust protection in automotive infotainment power supplies.
For engineers reviewing the SMCJ6.0CA-TR datasheet, SMCJ6.0CA-TR pinout, SMCJ6.0CA-TR application, or SMCJ6.0CA-TR equivalent, key selection criteria include bidirectional clamping behavior, 10.3 V max clamping voltage at 152 A, 150 °C junction temperature rating, low dynamic resistance (0.019 Ω), and IEC 61000-4-2 ±30 kV contact/air discharge compliance.
Technical Context
This TVS diode uses planar silicon junction technology optimized for low leakage and stable clamping across -55 °C to +150 °C operating range. Its bidirectional architecture provides symmetrical clamping for AC-coupled or floating signal paths without polarity dependency.
It meets IEC 61000-4-4 Level 4 (4 kV) and exceeds IEC 61000-4-2 Level 4 (±30 kV ESD), with thermal performance validated up to 1250 W at Tj = 150 °C. The device's 0.019 Ω dynamic resistance ensures minimal voltage overshoot during fast 8/20 µs surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRM) | 6.0 V - maximum continuous reverse working voltage before breakdown |
| Breakdown Voltage (VBR min) | 6.7 V at 10 mA - guarantees reliable conduction onset during overvoltage events |
| Clamping Voltage (VCL max) | 10.3 V at 152 A (10/1000 µs) - defines worst-case protected circuit voltage under surge |
| Peak Pulse Power (PPP) | 1500 W (10/1000 µs) - supports sustained surge energy in industrial power inputs |
| Leakage Current (IRM) | ≤0.2 µA at 6.0 V and 25 °C - prevents standby power loss in battery-backed systems |
| Junction Temperature Range | -55 °C to +150 °C - enables deployment in under-hood automotive or high-ambient industrial environments |
| ESD Rating | ±30 kV air/contact per IEC 61000-4-2 - eliminates need for external ESD staging in USB or CAN interfaces |
Pinout & Package
SMCJ6.0CA-TR is housed in an SMC (DO-214AB) surface-mount package with two terminals: Cathode (K) and Anode (A). The bidirectional configuration means both terminals function identically as symmetrical surge current paths - no polarity-sensitive mounting required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Surge current entry (positive or negative polarity) | Accepts transient current in either direction; connects to protected line |
| Cathode (K) | Surge current entry (positive or negative polarity) | Completes symmetrical clamping path; connects to reference plane (GND or VCC) |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals or floating buses without polarity constraints |
| Low dynamic resistance (RD) | 0.019 Ω minimizes clamping voltage rise under high di/dt transients |
| High-temperature surge capability | 1250 W peak power at 150 °C junction temperature ensures reliability in thermally stressed layouts |
| UL94 V0 epoxy housing | Self-extinguishing package material meets flammability requirements for enclosed power modules |
| JEDEC-registered SMC outline | Guarantees mechanical compatibility with standard SMT pick-and-place and reflow processes |
Applications
| Automotive Infotainment Power Rail | Industrial RS-485 Transceiver Protection |
|---|---|
Use Scenario: 12 V DC power input to head unit MCU and display driver ICs exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional TVS shunt that clamps transients below 10.3 V to prevent latch-up or gate oxide damage in downstream regulators and logic. Use Value: Withstands 1500 W surges while maintaining <0.2 µA leakage - avoids quiescent current penalty in always-on modules. | Use Scenario: Differential data lines (A/B) of RS-485 transceivers in factory automation PLCs subjected to cable-induced lightning surges. IC Role / Device Role / Timing Role: Fast-response voltage clamp placed across bus lines to limit differential-mode overvoltage to safe levels for transceiver I/O pins. Use Value: Symmetrical 10.3 V clamping on both polarities ensures equal protection during positive/negative surge events without polarity reversal concerns. |
| USB Type-C Port ESD Protection | AC-DC Adapter Feedback Loop Protection |
Use Scenario: VBUS and CC lines in USB-C receptacles requiring ±30 kV IEC 61000-4-2 ESD immunity per regulatory certification. IC Role / Device Role / Timing Role: Low-capacitance TVS diode absorbing ESD strikes before they reach USB controller PHY or PD controller. Use Value: 0.2 µA leakage preserves battery life in portable devices; bidirectional operation covers both VBUS and CC signal polarity states. | Use Scenario: Optocoupler feedback path in isolated 24 V AC-DC adapters where transient coupling into secondary-side control loop causes regulation instability. IC Role / Device Role / Timing Role: Clamping diode across optocoupler input to suppress common-mode surges induced by primary-side switching noise. Use Value: 150 °C rated junction temperature allows placement near hot transformer cores without derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0CA-TR | Lower 600 W peak power (10/1000 µs); same 6.0 V VRM and bidirectional structure | Restricted to lower-energy surge environments (e.g., consumer USB ports vs. industrial 24 V bus) | Select when board space is constrained (SMB vs SMC) and surge threat level is ≤600 W |
| 1.5KE6.8CA | Through-hole DO-201 package; 1500 W rating but higher 10.5 V clamping voltage at 134 A | Requires wave soldering; less suitable for high-density automated assembly | Choose for legacy through-hole designs or where manual repair access is prioritized over SMT scalability |
Compared with SMBJ6.0CA-TR and 1.5KE6.8CA, SMCJ6.0CA-TR uniquely balances high 1500 W surge capacity, low 10.3 V clamping, SMT-ready SMC packaging, and bidirectional symmetry - making it optimal for new industrial and automotive PCBs demanding compact, high-reliability transient suppression.

FAQ
What is the difference between SMCJ6.0CA-TR and SMCJ6.0A-TR?
SMCJ6.0CA-TR is bidirectional, providing symmetrical clamping for AC or floating signal lines, while SMCJ6.0A-TR is unidirectional and must be oriented with cathode toward the protected line's positive rail. Their electrical specs (VBR, VCL, PPP) are nearly identical, but CA versions enable polarity-agnostic placement - critical for differential buses like RS-485 or USB-C CC lines.
Does SMCJ6.0CA-TR require heatsinking for 1500 W surge handling?
No external heatsink is required for single-event 1500 W (10/1000 µs) surges because energy dissipation occurs too rapidly for significant thermal diffusion. However, PCB copper area under each lead (≥3 cm² recommended) is essential to maintain thermal impedance below 40 °C/W and prevent localized overheating during repetitive surges or elevated ambient temperatures.
Can SMCJ6.0CA-TR be used in place of a 5.0 V TVS diode?
No - its 6.0 V stand-off voltage (VRM) and 6.7 V minimum breakdown voltage make it unsuitable for 5.0 V systems where clamping must occur below 5.5 V. Using it risks insufficient protection margin; SMCJ5.0CA-TR (5.0 V VRM, 5.6 V VBR min) is the correct variant for 5 V rails such as USB 2.0 or microcontroller I/O protection.
How does temperature affect clamping voltage in SMCJ6.0CA-TR?
Clamping voltage increases linearly with junction temperature at +10⁻⁴/°C (αT). At 125 °C, VCL rises ~1.0% above its 25 °C value (10.3 V → ~10.4 V), and at 150 °C it reaches ~10.5 V. This predictable drift is factored into system-level margin analysis but does not compromise protection integrity within the rated Tj range.
