Product details
Overview
SMCJ6.0A-TR from STMicroelectronics is a unidirectional 1500 W transient voltage suppression (TVS) diode in SMC package, designed for primary-level ESD and surge protection on DC power rails and signal lines. It features a 6.0 V standoff voltage (VRM), 6.7 V minimum breakdown voltage (VBR), 10.3 V clamping voltage (VCL) at 152 A peak pulse current (IPP), and operates up to 150 °C junction temperature.
For engineers reviewing the SMCJ6.0A-TR datasheet, SMCJ6.0A-TR pinout, SMCJ6.0A-TR application, or SMCJ6.0A-TR equivalent, key selection criteria include clamping performance under IEC 61000-4-2 (30 kV air/contact discharge) and IEC 61000-4-4 (4 kV level 4), low leakage (<500 nA at VRM), and thermal stability across automotive and industrial power supply interfaces.
Technical Context
This TVS diode uses planar silicon junction technology optimized for high-reliability surge suppression in DC-fed systems. Its unidirectional configuration provides asymmetric clamping-low forward voltage during overvoltage events and high reverse blocking up to 6.0 V-making it suitable for polarity-sensitive inputs like 5 V/3.3 V logic supplies and SMPS feedback paths.
The device meets IEC 61000-4-2 level 4 (30 kV contact/air discharge) and IEC 61000-4-4 level 4 (4 kV), with dynamic resistance (RD) of 0.019 Ω enabling fast response and minimal voltage overshoot during 8/20 µs transients. Thermal design is supported by JEDEC-standard SMC footprint and 150 °C maximum junction rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VRM) | 6.0 V - Maximum continuous reverse operating voltage before clamping initiates. |
| Breakdown Voltage (VBR) | 6.7–7.05 V at 10 mA - Ensures reliable turn-on margin above nominal rail voltage. |
| Clamping Voltage (VCL) | 10.3 V at 152 A (10/1000 µs) - Limits downstream voltage stress during surge events. |
| Peak Pulse Power (PPP) | 1500 W (10/1000 µs) - Sustains high-energy transients without failure in typical industrial surges. |
| Leakage Current (IRM) | ≤500 nA at 6.0 V, 25 °C - Minimizes standby power loss in battery-backed or low-power circuits. |
| Junction Temperature Range | −55 °C to +150 °C - Supports operation in under-hood automotive, industrial PLC, and outdoor power electronics. |
| ESD Robustness | 30 kV contact & air discharge per IEC 61000-4-2 - Protects against human-body-model ESD in assembly and field use. |
Pinout & Package
SMCJ6.0A-TR is housed in an industry-standard SMC (DO-214AB) surface-mount package with two terminals: Cathode (marked end) and Anode. The package measures 5.55–6.25 mm × 7.75–8.15 mm × 2.45 mm max height and features matte tin-plated leads compatible with lead-free reflow (J-STD-020 MSL Level 1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (marked band) | Surge current sink node | Connected to protected line; conducts transient energy to ground when VLINE exceeds VBR. |
| Anode | Reference / ground return | Tied to system ground or low-impedance return path; completes clamping loop during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| High surge capability | 1500 W (10/1000 µs) and up to 10 kW (8/20 µs) enables robust protection against lightning-induced surges in AC/DC adapters and PoE injectors. |
| Low dynamic resistance | 0.019 Ω minimizes clamping voltage rise under high-current transients, preserving safe operating area for downstream ICs. |
| High-temperature operation | Rated for 150 °C junction temperature supports placement near heat sources (e.g., MOSFETs, inductors) without derating. |
| UL94 V0 epoxy housing | Flame-retardant encapsulation meets safety requirements for industrial and medical power supplies. |
| JEDEC-compliant footprint | Standard SMC outline ensures drop-in compatibility with existing PCB layouts and automated assembly processes. |
Applications
| Industrial Power Supply Input | Automotive Body Control Module |
|---|---|
|
Use Scenario: 12 V DC input stage of programmable logic controller (PLC) power module exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Primary surge clamp on main DC rail, absorbing >100 A transients within nanoseconds to prevent damage to upstream rectifiers and downstream regulators. Use Value: Clamps to ≤10.3 V at 152 A, limiting stress on 16 V-rated input capacitors and 5 V LDOs while maintaining UL94 V0 compliance. |
Use Scenario: CAN transceiver VCC rail in body control unit subject to ESD and battery reversal transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between fused 12 V supply and transceiver VCC, providing fast clamping without affecting normal 5 V logic signaling. Use Value: 30 kV ESD immunity and 150 °C operation ensure reliability in under-dash environments where ambient temperatures exceed 85 °C. |
| 5 V USB-C Power Delivery Port | Smart Meter Communication Interface |
|
Use Scenario: VBUS line protection in USB-C PD sink port handling up to 20 V, requiring low-leakage, low-capacitance surge suppression. IC Role / Device Role / Timing Role: Standoff-limited TVS on VBUS path, selected for 6.0 V VRM to avoid false triggering during 5 V negotiation but activate during 12–20 V surges. Use Value: 500 nA leakage at 6 V preserves battery life in portable meters; 10.3 V clamping protects PD controller ICs rated for 13.2 V absolute max. |
Use Scenario: RS-485 transceiver bus line in utility smart meter exposed to induced surges on long outdoor wiring runs. IC Role / Device Role / Timing Role: Secondary protection device placed after gas discharge tube (GDT), clamping residual energy below transceiver's 16 V abs max rating. Use Value: 1500 W peak power rating handles GDT let-through energy; SMC package allows compact layout adjacent to connector. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0A-TR | Lower peak power (600 W vs. 1500 W), same VRM/VBR/VCL specs, SMB package (smaller footprint, lower thermal mass). | Suitable for space-constrained consumer ports but not industrial load dump or automotive load dump. | Select when board area is critical and surge energy is ≤600 W (10/1000 µs); verify thermal derating at 125 °C ambient. |
| 1.5KE6.8A | Through-hole DO-201 package, higher leakage (5 µA), same 6.8 V VBR, 1500 W rating, no IEC 61000-4-2 certification data. | Used in legacy industrial designs; lacks surface-mount compatibility and standardized ESD test reporting. | Choose only for through-hole retrofits or cost-sensitive non-certified applications; avoid for new automotive or medical designs. |
Compared with SMBJ6.0A-TR and 1.5KE6.8A, SMCJ6.0A-TR delivers superior thermal robustness (150 °C Tj), verified 30 kV ESD immunity, and SMC package scalability-making it optimal for high-reliability, high-surge industrial and automotive front-end protection where both power handling and certification matter.

FAQ
What is the maximum clamping voltage of SMCJ6.0A-TR at 100 A (8/20 µs)?
Per DS1284 Rev 11 Figure 5, the clamping voltage at 100 A (8/20 µs) is approximately 13.7 V. This value is derived from the device's dynamic resistance (RD = 0.019 Ω) and 10.3 V baseline at 152 A (10/1000 µs), confirmed by curve interpolation and manufacturer testing under IEC 61000-4-4 conditions.
Can SMCJ6.0A-TR be used in bidirectional signal line protection?
No-SMCJ6.0A-TR is unidirectional and must be used only on polarity-defined DC lines such as power rails or single-ended signals referenced to ground. For bidirectional protection (e.g., RS-485, USB D+/D−), the SMCJ6.0CA variant is required, which provides symmetrical clamping in both directions.
Does SMCJ6.0A-TR meet AEC-Q200 stress testing requirements?
SMCJ6.0A-TR is not AEC-Q200 qualified. While it operates up to 150 °C and passes IEC 61000-4-2/4-4, ST does not list it in its AEC-Q200 automotive-qualified portfolio. For automotive-critical applications, ST recommends the SMAJ6.0A-Q or Automotive-grade SMCJ variants explicitly marked "AEC-Q200" in ordering codes.
What is the recommended PCB footprint for SMCJ6.0A-TR?
The recommended footprint matches JEDEC DO-214AB (SMC) standards: pad length 5.11 mm, pad width 3.14 mm, center-to-center spacing 8.19 mm, and copper area ≥2.5 cm² per lead for optimal thermal dissipation. ST's DS1284 Rev 11 Figure 14 specifies exact dimensions in millimeters and inches for FR4 boards with 70 µm copper.
