Product details
Overview
SMCJ130C 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), 144–176V breakdown voltage (VBR), and 231V maximum clamping voltage (VC) at 6.8A peak impulse current - designed for automotive load-dump and ISO 7637-2 Pulse 1/2a/2b/3a/3b protection in power supply rails.
For engineers reviewing the SMCJ130C datasheet, SMCJ130C pinout, SMCJ130C application, or SMCJ130C equivalent, this device delivers verified clamping performance under fast transients (<1.0 ps response), low leakage (<1 µA @ 130V), and robust thermal derating (RθJA = 55°C/W) - critical for ECU, infotainment, and ADAS power rail hardening.
Technical Context
The SMCJ130C is a bipolar (bidirectional) TVS diode optimized for high-energy surge suppression without polarity sensitivity. It operates symmetrically in both directions, with identical VBR min/max (144–176 V), VC (231 V), and IPPM (6.8 A) ratings across reverse and forward quadrants.
Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive transients. Compliance with ISO 7637-2 Pulse 1 (inductive switch-off), Pulse 2a/2b (battery disconnect/load dump), and Pulse 3a/3b (capacitive coupling) confirms suitability for automotive 12 V/24 V systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |

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 (Bourns) | Same VWM (130 V), lower PPK (600 W), higher VC (250 V), SMB package (smaller footprint) | Limited to lower-energy transients; unsuitable for full ISO 7637-2 Pulse 2b load dump | Select only for space-constrained non-automotive applications where 1500 W surge headroom is not required. |
| 1.5KE130CA (ON Semiconductor) | Same VWM/VBR/VC specs, but axial DO-15 package - not surface-mountable | Requires through-hole assembly; incompatible with automated SMT lines and high-density PCB layouts | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not needed. |
Compared with SMBJ130CA and 1.5KE130CA, the SMCJ130C uniquely combines 1500 W surge rating, DO-214AB SMT compatibility, and full ISO 7637-2 compliance - making it the only option qualified for production automotive power rail hardening without layout or process compromise.

FAQ
What is the clamping voltage of the SMCJ130C under a standard 10/1000 µs surge?
The SMCJ130C has a maximum clamping voltage (VC) of 231 V when subjected to its rated peak impulse current of 6.8 A, defined by the 10/1000 µs waveform per IEC 61000-4-5. This value is measured at the device terminals and represents the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream components remain within safe operating area.
Is the SMCJ130C unidirectional or bidirectional, and how does that affect circuit placement?
The SMCJ130C is a bidirectional TVS diode, indicated by the "C" suffix per Taiwan Semiconductor's naming convention. It provides symmetrical clamping in both polarities, eliminating need for polarity-aware placement. Unlike unidirectional variants (e.g., SMCJ130A), it protects AC-coupled lines, floating grounds, or dual-rail systems without orientation constraints - simplifying layout and reducing BOM count.
Does the SMCJ130C meet automotive transient immunity standards?
Yes, the SMCJ130C meets ISO 7637-2 requirements for Pulses 1 (inductive switch-off), 2a/2b (battery disconnection and load dump), and 3a/3b (capacitive coupling and ESD-like transients). Its 1500 W peak power rating, 231 V clamping, and sub-1 ps response enable reliable protection of 12 V and 24 V automotive ECUs, infotainment units, and body control modules per OEM specifications.
What is the maximum junction temperature and thermal resistance of the SMCJ130C?
The SMCJ130C has a maximum junction temperature (TJ) of +150 °C and a junction-to-ambient thermal resistance (RθJA) of 55 °C/W under standard JEDEC test conditions. These values define its safe operating envelope: at 25 °C ambient, it can dissipate up to 5 W continuously, and must be mounted on adequately copper-poured PCBs to maintain TJ ≤150 °C during repeated surge events.
How does the SMCJ130C compare to the SMCJ130A in terms of electrical performance?
The SMCJ130C is bidirectional with symmetrical VBR (144–176 V) and VC (231 V) in both directions, while the SMCJ130A is unidirectional - conducting only in reverse bias and featuring a forward voltage drop (~3.5 V) under high current. The SMCJ130C's bidirectional nature makes it suitable for AC or polarity-agnostic DC protection, whereas the SMCJ130A is intended for DC rails with known polarity and requires correct orientation during placement.
