Product details
Overview
SMCJ130CA from Taiwan Semiconductor is a bidirectional 1500W surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, with 130V working stand-off voltage (VWM), 144–159V breakdown voltage (VBR), and 209V maximum clamping voltage (VC) at 7.5A peak pulse current - designed for automotive load-dump and ISO 7637-2 Pulse 1/2a/2b/3a/3b protection in power supply rails and CAN/LIN bus interfaces.
For engineers reviewing the SMCJ130CA datasheet, SMCJ130CA pinout, SMCJ130CA application, or SMCJ130CA equivalent, key selection criteria include clamping performance under 10/1000μs surge, unidirectional vs. bidirectional configuration (CA = bidirectional), thermal derating above 25°C, and compliance with JESD201 Class 2 whisker resistance and UL 94V-0 molding compound requirements.
Technical Context
The SMCJ130CA uses a glass-passivated silicon junction to achieve sub-1ps response time from 0V to VBR(min), enabling effective suppression of fast EFT and ESD transients. Its bidirectional architecture supports symmetrical clamping in both polarities without external polarity management.
Thermal design relies on RθJC = 10°C/W and RθJA = 55°C/W, with steady-state power dissipation limited to 5W at 25°C ambient and full 1500W peak pulse capability only at TA = 25°C - derated linearly per Fig.2 above that temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 144 V / 159 V @ IT = 1 mA - ensures reliable turn-on within defined tolerance band |
| VC @ IPPM | 209 V @ 7.5 A (10/1000μs waveform) - peak clamped voltage seen by protected circuit |
| PPK | 1500 W - peak pulse power handling capacity under standardized surge conditions |
| IR @ VWM | <1 μA - negligible leakage current at rated stand-off voltage, minimizing standby power loss |
| TJ max | +150 °C - maximum junction temperature defining safe operating area under thermal stress |
| Package | DO-214AB (SMC) - industry-standard surface-mount outline with 0.210 g mass and J-STD-002 solderability |
Pinout & Package
DO-214AB (SMC) package: molded plastic case with matte tin-plated leads, polarity indicated by cathode band (not applicable for bidirectional SMCJ130CA); terminals are non-polarized and symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional transient conduction path | Either terminal serves as anode or cathode depending on transient polarity - no orientation required during placement |
| Case | Non-electrical mechanical interface | Plastic body provides insulation and mechanical anchoring; no thermal or electrical connection to die |
Key Features
| Feature | Design Value |
|---|---|
| ISO 7637-2 compliance | Validated for Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (EFT) - enables drop-in use in automotive ECUs |
| Glass passivated junction | Enhances long-term reliability under humidity and thermal cycling vs. epoxy-passivated alternatives |
| Moisture sensitivity level 1 | No floor-life limitation or bake requirement prior to reflow - simplifies SMT line logistics |
| Halogen-free construction | Meets IEC 61249-2-21 - supports RoHS-compliant and environmentally regulated end equipment |
| Fast response time | <1.0 ps from 0 V to VBR(min) - clamps before most IC input structures experience damage |
Applications
| Automotive Power Rail Protection | CAN/LIN Bus Transient Suppression |
|---|---|
Use Scenario: 12V/24V battery-fed microcontroller power inputs exposed to load-dump events up to ±120V. IC Role / Device Role / Timing Role: Primary clamping device placed directly at power entry point before DC-DC converter input.

IC Role / Device Role / Timing Role: Bidirectional TVS connected across CAN_H/CAN_L pair, referenced to ground via low-inductance layout. Use Value: Clamps common-mode surges to <209V while preserving signal integrity - meets ISO 11898-2 EMC immunity requirements. |
| Industrial PLC I/O Protection | LED Driver Surge Immunity |
Use Scenario: Digital input channels receiving 24V DC signals from field sensors in factory automation cabinets. IC Role / Device Role / Timing Role: Standoff protection element placed between connector and optocoupler input stage. Use Value: Absorbs repetitive 1 kV/500 A surges (IEC 61000-4-5 Level 3) without degradation, extending system uptime. | Use Scenario: Constant-current LED driver outputs driving high-brightness arrays in outdoor signage.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC130CA | Same VWM (130V), lower PPK (1000W), higher VC (220V @ 5.5A) | Lower surge margin; suitable only where peak currents ≤5.5A expected | Select SAC130CA only if board space constraints prevent DO-214AB footprint or if 1000W rating suffices |
| 1.5KE130CA | Through-hole TO-218 package, same VWM/VC specs, identical 1500W rating | Requires through-hole assembly; not compatible with automated SMT lines | Choose 1.5KE130CA only for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with SAC130CA and 1.5KE130CA, the SMCJ130CA delivers identical 130V standoff and bidirectional operation in a surface-mount DO-214AB package optimized for high-volume automotive production, offering superior thermal performance (RθJC = 10°C/W) and moisture resilience (MSL 1).

FAQ
What does the "CA" suffix mean in SMCJ130CA?
The "CA" suffix in SMCJ130CA indicates a bidirectional configuration - meaning the device clamps transients of either polarity across its terminals. Unlike unidirectional variants (e.g., SMCJ130A), the SMCJ130CA has no cathode marking and functions identically regardless of orientation during PCB placement.
What is the maximum clamping voltage of SMCJ130CA under standard test conditions?
The SMCJ130CA has a maximum clamping voltage (VC) of 209 V when subjected to a 10/1000 μs surge waveform at 7.5 A peak current (IPPM). This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuits during worst-case transients.
Is SMCJ130CA compliant with automotive EMC standards?
Yes, the SMCJ130CA meets ISO 7637-2 requirements for Pulse 1 (inductive load dump), Pulse 2a/2b (supply interruption), and Pulse 3a/3b (electrical fast transients), making it suitable for front-end protection in automotive ECUs, body controllers, and infotainment power supplies.
Can SMCJ130CA be used in place of a unidirectional TVS like SMCJ130A?
No - the SMCJ130CA is bidirectional and cannot replace unidirectional SMCJ130A in circuits requiring polarity-specific clamping (e.g., DC rail-to-ground protection). Substitution requires verifying circuit topology, grounding scheme, and whether reverse-bias leakage or forward conduction paths are acceptable.
What is the thermal resistance profile of SMCJ130CA?
The SMCJ130CA has a junction-to-case thermal resistance (RθJC) of 10°C/W and junction-to-ambient resistance (RθJA) of 55°C/W at 25°C ambient. These values require adequate copper pour and thermal vias for sustained power dissipation - especially critical when operating near TJ(max) = +150°C.
