Product details
Overview
SMCJ130CH from Taiwan Semiconductor is a bidirectional 1500W surface-mount transient voltage suppressor (TVS) in DO-214AB (SMC) package, with 130V working stand-off voltage (VWM), 144–176V breakdown voltage (VBR), and 231V maximum clamping voltage (VC) at 6.8A peak pulse current - designed for automotive-grade ESD and surge protection in power supply rails and signal lines.
For engineers reviewing the SMCJ130CH datasheet, SMCJ130CH pinout, SMCJ130CH application, or SMCJ130CH equivalent, key selection criteria include AEC-Q101 qualification, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, sub-1ps response time, <1μA reverse leakage at VWM, and bidirectional clamping symmetry for robust DC bus and CAN/LIN line protection.
Technical Context
The SMCJ130CH uses a glass-passivated silicon junction to achieve fast transient response (<1.0 ps from 0 V to VBR min) and stable clamping under repetitive surge stress. Its bidirectional configuration enables symmetrical protection without polarity dependency, supporting both positive and negative transients across the same terminals.
Thermally, it features RθJA = 55°C/W and RθJC = 10°C/W, enabling reliable operation up to TJ = +150°C. It meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity - critical for reflow-compatible automotive PCB assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before clamping initiates; defines safe DC bias margin for protected circuitry. |
| VBR min/max | 144 V / 176 V @ IT = 1 mA - Verified breakdown threshold range ensures consistent turn-on behavior across production lots. |
| VC @ IPPM | 231 V @ 6.8 A (10/1000 µs waveform) - Peak clamped voltage limits downstream component stress during ISO 7637-2 Pulse 5a surges. |
| PPK | 1500 W - Peak pulse power rating determines survivability against high-energy transients like load dump or lightning-induced surges. |
| IR @ VWM | <1 µA - Ultra-low leakage preserves signal integrity and minimizes standby power loss in always-on systems. |
| Package | DO-214AB (SMC) - Standardized surface-mount outline with 0.210 g mass, UL 94V-0 molding, and matte tin-plated leads for J-STD-002 solderability. |
| AEC-Q101 | Qualified - Validated for automotive underhood and body electronics per stress test requirements including HTOL, TC, and HAST. |
Pinout & Package
DO-214AB (SMC) package: surface-mount, bidirectional, cathode-band-free construction. Terminals are unmarked and functionally symmetric - both leads serve as interchangeable anode/cathode depending on transient polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals conduct equally in either direction; no polarity marking required - simplifies layout and eliminates orientation errors. |
Key Features

| ISO 7637-2 compliance | Meets Pulse 1 (inductive load disconnect), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling) - covers full vehicle-level EMC immunity. |
| Glass-passivated junction | Enhances long-term reliability and stability of VBR and leakage under thermal/humidity stress versus epoxy-passivated alternatives. |
| Sub-1 ps response time | Clamps within 1 picosecond of transient onset - faster than most microcontroller I/O protection diodes, preserving signal edge integrity. |
| Level 1 moisture sensitivity | Zero bake requirement prior to reflow; compatible with standard SMT lines without dry-pack handling or floor-life constraints. |
Applications
| Automotive Power Distribution | Industrial CAN Bus Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA | Lower PPK (600 W), smaller SMB package (RθJA = 85°C/W), same VWM/VBR range and bidirectional structure. | Suitable for space-constrained consumer or industrial boards where 1500 W surge margin is not required. | Select SMBJ130CA only if peak surge energy is ≤600 W and thermal budget allows higher junction rise. |
| 1.5KE130CA | Through-hole TO-218 package, 1500 W rating, but slower response (>1 ns), higher IR (≤5 µA), and no AEC-Q101 qualification. | Acceptable for non-automotive industrial controls where board-level reflow compatibility is not needed. | Choose 1.5KE130CA only for legacy through-hole designs or cost-sensitive non-automotive applications lacking AEC-Q101 mandates. |
Compared with SMBJ130CA and 1.5KE130CA, the SMCJ130CH delivers automotive-grade reliability, superior thermal performance (RθJC = 10°C/W), and faster transient capture - making it the sole option qualified for modern vehicle power domain architectures requiring zero derating at 125°C ambient.

FAQ
What does the "CH" suffix indicate in SMCJ130CH?
The "CH" suffix denotes a bidirectional configuration with glass-passivated junction and AEC-Q101 qualification. Unlike unidirectional variants (e.g., SMCJ130H), the SMCJ130CH provides symmetrical clamping for both polarities - essential for protecting AC-coupled or differential interfaces such as CAN, LIN, or Ethernet PHYs without polarity concerns. This makes SMCJ130CH distinct from its unidirectional counterparts in both electrical behavior and application scope.
Is SMCJ130CH compliant with ISO 7637-2, and which pulses does it cover?
Yes, SMCJ130CH is explicitly rated to meet ISO 7637-2 for Pulses 1, 2a, 2b, 3a, and 3b - covering inductive load dump, switching transients, and capacitive coupling events common in automotive 12 V/24 V systems. Its 1500 W peak power rating and 231 V clamping voltage at 6.8 A ensure compliance with Pulse 5a (load dump) when used with appropriate series impedance, as validated in Taiwan Semiconductor's application notes for vehicle-level EMC design.
What is the maximum junction temperature and thermal resistance of SMCJ130CH?
The SMCJ130CH has a maximum junction temperature (TJ) of +150°C and thermal resistances of RθJA = 55°C/W (junction-to-ambient) and RθJC = 10°C/W (junction-to-case). These values are measured under standard JEDEC conditions and enable reliable operation in under-hood environments up to +125°C ambient when mounted on 1-in² 2-oz copper with two thermal vias - critical for engine control unit (ECU) and ADAS module deployments.
How does SMCJ130CH differ from SMCJ130AH?
The SMCJ130AH has a tighter VBR range (144–159 V vs. 144–176 V for SMCJ130CH) and lower clamping voltage (209 V vs. 231 V at 7.5 A), reflecting tighter process control for precision-clamp applications. However, SMCJ130CH offers broader VBR tolerance and is optimized for general-purpose automotive surge suppression where absolute clamping consistency is secondary to robustness and cost efficiency - making SMCJ130CH preferred for high-volume ECU power rail protection.
Can SMCJ130CH be used in place of a unidirectional TVS like SMCJ130H?
No - SMCJ130CH is bidirectional and lacks polarity marking, while SMCJ130H is unidirectional with a cathode band. Substituting SMCJ130CH for SMCJ130H on a DC rail may cause forward conduction during normal operation due to its symmetrical IV curve. The SMCJ130CH must only replace other bidirectional TVS devices (e.g., SMCJ130CA) and requires verification that the protected circuit tolerates bidirectional clamping behavior - especially in single-supply analog or digital signal paths.
