Product details
Overview
SMBJ130C from Taiwan Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 130V working stand-off voltage (VWM), 231V maximum clamping voltage (VC@IPP) at 2.7A peak impulse current, and 600W peak pulse power dissipation with a 10/1000µs waveform - deployed in automotive lighting control, industrial I/O protection, and DC power rail ESD hardening.
For engineers reviewing the SMBJ130C datasheet, SMBJ130C pinout, SMBJ130C application, or SMBJ130C equivalent, key selection criteria include unidirectional vs. bidirectional configuration (C suffix = bidirectional), DO-214AA (SMB) package compatibility, clamping performance under ISO 7637-2 Pulse 1/2a/2b/3a/3b, and leakage current ≤1µA at 130V.
Technical Context
The SMBJ130C implements a silicon avalanche junction structure with glass passivation for stable breakdown behavior and low leakage. Its bidirectional configuration enables symmetrical clamping in AC-coupled or floating signal paths without polarity sensitivity.
It delivers sub-1ps response time to transients and meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity - enabling reliable reflow soldering and long-term operation in harsh environments up to +150°C junction temperature.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA | Same VWM (130V), identical VBR (144–176V), but CA suffix indicates halogen-free variant with tighter ID spec (≤0.5µA vs. ≤1µA) | Required where stricter halogen-free compliance (IEC 61249-2-21) or lower leakage is mandated | Select SMBJ130CA when BOM requires full halogen-free certification or ultra-low standby leakage |
| SMAJ130C | Lower PPK (400W vs. 600W), same DO-214AC (SMA) package - smaller thermal mass and reduced surge capacity | Suitable only for lower-energy transients (e.g., IEC 61000-4-2 ESD only), not ISO 7637-2 load dump | Choose SMAJ130C only if space constraints prohibit SMB package and surge energy is limited to ≤400W |
Compared with SMBJ130CA and SMAJ130C, the SMBJ130C provides optimal balance of 600W surge rating, DO-214AA mechanical robustness, and verified ISO 7637-2 compliance - making it the preferred choice for automotive and industrial power-line protection where full-standard immunity is required.

FAQ
What does the 'C' suffix indicate in SMBJ130C?
The 'C' suffix in SMBJ130C denotes a bidirectional configuration - meaning the device clamps transients equally in both polarities without requiring orientation during PCB placement. This differs from unidirectional variants (e.g., SMBJ130A), which have defined anode/cathode terminals and require correct polarity alignment. The SMBJ130C is functionally identical to SMBJ130CA except for halogen-free material compliance.
What is the maximum clamping voltage of SMBJ130C and under what test condition?
The SMBJ130C has a maximum clamping voltage (VC) of 231 V, measured at a peak impulse current (IPP) of 2.7 A using the standard 10/1000 µs double-exponential surge waveform. This value is guaranteed across the full operating temperature range and ensures downstream circuitry remains below destructive voltage thresholds during transient events.
Is SMBJ130C compliant with automotive transient standards?
Yes, SMBJ130C meets ISO 7637-2 requirements for Pulse 1 (inductive load disconnect), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling and ignition noise). Its 600W peak pulse power rating and sub-1ps response time enable robust protection in 12V and 24V automotive subsystems including lighting, body control, and sensor interfaces.
What is the junction-to-ambient thermal resistance (RθJA) of SMBJ130C?
The SMBJ130C has a junction-to-ambient thermal resistance (RθJA) of 55 °C/W, measured under standard JEDEC conditions (single device on 1-inch² FR-4 board with 2 oz copper). This value supports thermal design for continuous operation up to +150°C junction temperature when mounted with adequate copper pour and airflow.
Does SMBJ130C require orientation during PCB assembly?
No - SMBJ130C is a bidirectional TVS diode with symmetrical terminals, so no polarity marking or orientation is required during placement. Unlike unidirectional variants (e.g., SMBJ130A), it functions identically regardless of how it is mounted across a differential or floating node, simplifying automated assembly and reducing misplacement risk.
