Product details
Overview
SMA6J5.0CA-TR from STMicroelectronics is a bidirectional 600 W transient voltage suppression diode designed for IEC 61000-4-2 ESD and IEC 61000-4-4 surge protection in power rails and signal lines. It features a 5.0 V standoff voltage (VRM), 9.1 V clamping voltage at 68 A (10/1000 µs), and operates up to 175 °C junction temperature. Used in USB ports, industrial I/O modules, and automotive body control units requiring robust overvoltage immunity.
For engineers reviewing the SMA6J5.0CA-TR datasheet, SMA6J5.0CA-TR pinout, SMA6J5.0CA-TR application, or SMA6J5.0CA-TR equivalent, key selection criteria include bidirectional clamping behavior, low leakage (<1 µA at 85 °C), JEDEC DO-214AC (SMA) package compatibility, and IEC 61000-4-2 level 4 compliance (30 kV contact/air discharge).
Technical Context
This TVS diode uses planar silicon technology to achieve stable breakdown characteristics and low dynamic resistance (0.027 Ω at 8/20 µs). Its bidirectional structure enables symmetrical clamping on AC-coupled or floating lines without polarity constraints.
The device meets MIL-STD-883 method 3015 for ESD and IEC 61000-4-4 level 4 (4 kV), with clamping voltage defined across both polarities. Thermal design relies on FR4 PCB copper area under leads, where Rth(j-a) drops from 140 °C/W (no copper) to <4.5 °C/W (5 cm² per lead).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VRM) | 5.0 V - Maximum continuous reverse working voltage before significant leakage. |
| Clamping Voltage (VCL) | 9.1 V at 68 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case surge. |
| Peak Pulse Power | 600 W (10/1000 µs) - Sustained energy absorption capability for standard lightning surges. |
| Leakage Current | ≤1 µA at 85 °C - Ensures minimal standby power loss in battery-powered interfaces. |
| Junction Temperature Range | –55 °C to +175 °C - Supports operation in under-hood automotive or industrial motor drive environments. |
| ESD Withstand | 30 kV contact & air discharge (IEC 61000-4-2 level 4) - Eliminates need for external ESD staging in USB 2.0 or CAN FD transceivers. |
| Dynamic Resistance | 0.027 Ω (8/20 µs) - Low impedance limits voltage overshoot during fast-rising transients. |
Pinout & Package
Package: DO-214AC (SMA), JEDEC registered, IPC-7531 compliant footprint, matte tin-plated leads, UL94 V0 resin housing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (K) | Reference terminal for unidirectional devices; symmetric terminal in bidirectional configuration | In SMA6J5.0CA-TR, both terminals are functionally identical - no polarity marking required for AC line protection. |
| Anode (A) | Reference terminal for unidirectional devices; symmetric terminal in bidirectional configuration | Terminal pair forms a back-to-back Zener structure enabling equal clamping in both directions. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of differential buses (e.g., RS-485, CAN) without polarity concerns. |
| Low dynamic resistance (0.027 Ω) | Reduces clamping voltage rise under high-current transients, improving system-level surge margin. |
| 175 °C max operating junction temperature | Supports placement near heat sources (e.g., power MOSFETs, DC-DC converters) without derating. |
| JEDEC DO-214AC (SMA) package | Standardized footprint ensures drop-in replacement and automated assembly compatibility across suppliers. |
| UL94 V0 flammability rating | Meets safety requirements for enclosed industrial and automotive enclosures without additional flame barriers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0CA | Same VRM/VCL specs but SMB package (DO-214AA); 100 W higher peak power (700 W @ 10/1000 µs) | Larger footprint; better suited for high-reliability industrial boards with ample layout space | Select when board space allows larger package and higher surge margin is required. |
| 1.5KE5.0CA | Higher peak power (1500 W), axial-leaded DO-15 package, higher leakage (5 µA @ 85 °C) | Through-hole mounting only; unsuitable for automated SMT production or compact designs | Choose only for legacy through-hole systems or cost-sensitive non-automated assemblies. |
Compared with SMBJ5.0CA and 1.5KE5.0CA, SMA6J5.0CA-TR offers optimal balance of SMT compatibility, thermal performance (175 °C Tj), and low leakage-making it preferred for space-constrained, high-temperature embedded applications requiring full IEC 61000-4-2/4-4 compliance.

FAQ
What is the difference between SMA6J5.0A-TR and SMA6J5.0CA-TR?
SMA6J5.0A-TR is unidirectional and clamps only in reverse bias, requiring correct polarity installation. SMA6J5.0CA-TR is bidirectional, formed by two Zeners in series opposition, enabling symmetrical clamping on AC or floating lines without orientation constraints-ideal for differential buses like RS-485 or LIN.
Does SMA6J5.0CA-TR meet automotive AEC-Q200 requirements?
No-SMA6J5.0CA-TR is not AEC-Q200 qualified. While it operates up to 175 °C junction temperature and passes IEC 61000-4-2/4-4, ST does not list it in its AEC-Q200 stress-tested portfolio. For automotive-grade TVS, consider ST's Automotive Qualified SMAJ5.0CA or SM8S5.0CA series.
What is the recommended PCB footprint for SMA6J5.0CA-TR?
The recommended IPC-7531 compliant footprint has pad dimensions of 1.40 mm × 2.63 mm (0.055″ × 0.104″), 5.43 mm center-to-center spacing, and 1.64 mm pad length. Copper area ≥2 cm² per lead reduces thermal resistance to <100 °C/W, critical for sustained surge handling.
Can SMA6J5.0CA-TR be used for 12 V automotive supply rail protection?
No-it is not suitable for 12 V rail clamping. With a 5.0 V standoff voltage, it would conduct continuously under normal 12 V operation. For 12 V systems, use SMA6J12CA-TR (12 V VRM) or SMA6J13CA-TR (13 V VRM) to ensure proper blocking and reliable surge response.
