Product details
Overview
SMCJ130CA-TR from STMicroelectronics is a bidirectional 1500 W transient voltage suppression diode in SMC package, designed for high-energy ESD and surge protection in DC power lines and data interfaces. It features a standoff voltage (VRM) of 130 V, clamping voltage (VCL) of 209 V at 7.5 A (10/1000 µs), leakage current ≤0.2 µA at 25 °C, and operates up to +150 °C junction temperature.
For engineers reviewing the SMCJ130CA-TR datasheet, SMCJ130CA-TR pinout, SMCJ130CA-TR application, or SMCJ130CA-TR equivalent, this device is selected for robust overvoltage protection in industrial power supplies, telecom line cards, and automotive body control modules where low leakage, high Tj capability, and IEC 61000-4-2/4-4 compliance are critical.
Technical Context
This bidirectional TVS diode uses planar junction technology to achieve stable breakdown behavior and low dynamic resistance (RD = 6.59 Ω at 25 °C). Its symmetrical clamping response protects both polarities of AC-coupled or floating signal lines without polarity constraints.
It delivers 1500 W peak pulse power (10/1000 µs) at 25 °C and retains 1250 W at Tj = 150 °C - validated per IEC 61000-4-4 level 4 (4 kV) and IEC 61000-4-2 (30 kV air/contact discharge), exceeding standard industrial immunity requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VRM) | 130 V - maximum continuous reverse operating voltage before conduction begins |
| Breakdown Voltage (VBR min) | 144 V at 1 mA - guaranteed minimum avalanche initiation voltage under DC test |
| Clamping Voltage (VCL) | 209 V at 7.5 A (10/1000 µs) - peak voltage seen by protected circuit during surge |
| Peak Pulse Power (PPP) | 1500 W (10/1000 µs) - energy-handling capacity for standard lightning-surge waveform |
| Leakage Current (IRM) | ≤0.2 µA at 130 V, 25 °C - negligible standby power loss and minimal impact on high-impedance circuits |
| Junction Temperature Range | –55 °C to +150 °C - enables use in under-hood automotive or enclosed industrial environments |
| Dynamic Resistance (RD) | 6.59 Ω - determines voltage rise per additional ampere of surge current beyond rated IPP |
Pinout & Package
The SMCJ130CA-TR is housed in an SMC (DO-214AB) surface-mount package with two terminals: Cathode and Anode, arranged symmetrically for bidirectional operation. The package meets IPC7531 footprint standards and JEDEC MO-136AC outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Surge current entry point (negative polarity) | Conducts during negative transients; forms symmetrical clamping path with Cathode |
| Cathode (K) | Surge current entry point (positive polarity) | Conducts during positive transients; enables bidirectional clamping without external polarity selection |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping architecture | Protects AC-coupled or floating lines (e.g., RS-485, CAN, Ethernet PHY) without polarity sensitivity |
| Low leakage current (≤0.2 µA) | Preserves signal integrity and battery life in always-on systems such as IoT sensor nodes and telematics units |
| High junction temperature rating (+150 °C) | Supports placement near heat sources (e.g., power MOSFETs, transformers) without derating concerns |
| IEC 61000-4-2 level 4 compliance (30 kV) | Validated for direct ESD strikes in harsh industrial and automotive assembly/test environments |
| Matte tin lead finish | Enables RoHS-compliant reflow soldering per J-STD-020 MSL level 1, eliminating whisker risk |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA-TR | Lower PPP (600 W vs. 1500 W); same VRM/VCL but higher RD (10.8 Ω) | Restricted to lower-energy surges (e.g., board-level ESD only, not system-level lightning) | Select when space-constrained SMB package is required and surge energy is limited to ≤600 W. |
| 1.5KE130CA | Through-hole DO-201 package; identical electrical specs but larger footprint and no MSL-1 reflow rating | Not suitable for automated SMT production; requires wave soldering or hand assembly | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required. |
Compared with SMBJ130CA-TR and 1.5KE130CA, the SMCJ130CA-TR uniquely balances high 1500 W surge capability, SMT manufacturability, and 150 °C thermal endurance - making it optimal for volume production of industrial and automotive electronics requiring robust, automated ESD protection.

FAQ
What is the difference between SMCJ130CA-TR and SMCJ130A-TR?
The "CA" suffix denotes bidirectional configuration, meaning it clamps both positive and negative transients symmetrically across its terminals. The "A" version is unidirectional and conducts only in reverse bias - requiring correct polarity orientation in-circuit. This makes SMCJ130CA-TR ideal for AC-coupled or floating signal lines like RS-485 or CAN, whereas SMCJ130A-TR suits DC rails with known polarity.
Can SMCJ130CA-TR be used in parallel for higher surge current handling?
No - paralleling TVS diodes without matched VBR and dynamic resistance causes current imbalance and premature failure. ST does not recommend parallel operation. For higher current, select a single higher-rated device (e.g., 5.0SMDJ130CA) or implement staged protection with GDT + TVS cascading.
Is the SMCJ130CA-TR compliant with AEC-Q200?
No - it is not AEC-Q200 qualified. While it operates up to +150 °C junction temperature and meets IEC 61000-4-2/4-4, ST positions the SMCJ series for industrial and general automotive applications, not automotive safety-critical subsystems. For AEC-Q200, consider ST's Automotive TVS portfolio (e.g., SMAJ130A-Q).
What PCB layout practices maximize SMCJ130CA-TR performance?
Minimize trace inductance by placing the device directly across the protected line and ground with short, wide copper pours. Use ≥2 cm² copper area per pad (per Figure 12) to reduce Rth(j-a) and sustain 1500 W pulses. Avoid vias in current paths and ensure thermal relief is omitted from pads to maintain low-impedance surge conduction.
