Product details
Overview
SMBJ130CH from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, designed for high-energy ESD and surge protection in automotive and industrial power rails. It features a 130 V working stand-off voltage (VWM), 144–176 V breakdown voltage (VBR), 231 V maximum clamping voltage (VC) at 2.7 A peak pulse current (IPP), and 600 W peak pulse power rating with sub-1 ps response time.
For engineers reviewing the SMBJ130CH datasheet, SMBJ130CH pinout, SMBJ130CH application, or SMBJ130CH equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, low leakage (<1 µA at 130 V), and thermal resistance (RθJA = 55 °C/W) for reliable operation in harsh environments.
Technical Context
The SMBJ130CH is a unidie, glass-passivated, bidirectional TVS diode optimized for fast transient suppression on DC power lines and signal paths subject to load dump, inductive switching, and EFT events. Its symmetrical I-V characteristics enable identical clamping in both polarities, eliminating polarity concerns during board layout.
It operates across -55 °C to +150 °C junction temperature range, meets JESD201 Class 2 whisker resistance, and is rated for 100 A non-repetitive forward surge (IFSM) - supporting robust protection in 12 V/24 V automotive subsystems and industrial PLC I/O modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous DC or RMS voltage the device blocks without conduction |
| VBR (min/max) | 144 V / 176 V @ 1 mA - Ensures reliable turn-on above system operating voltage with margin |
| VC @ IPP | 231 V @ 2.7 A (10/1000 µs) - Limits downstream voltage stress during worst-case transients |
| PPK | 600 W - Sustains high-energy surges per ISO 7637-2 without degradation |
| IR @ VWM | <1 µA - Negligible standby power loss and minimal impact on high-impedance circuits |
| RθJA | 55 °C/W - Enables thermal design for PCB-mounted operation without forced cooling |
| Response time | <1.0 ps - Clamps before most semiconductor junctions can be damaged by fast transients |
Pinout & Package
DO-214AA (SMB) surface-mount package with cathode band marking; two-terminal bidirectional configuration - no anode/cathode distinction required in circuit design.
| Pin/Terminal | Circuit Role | 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 | Same VWM (130 V), VBR (144–176 V), and VC (231 V); identical DO-214AA package and AEC-Q101 qualification | No functional difference; CA suffix denotes same bidirectional specification as CH in Taiwan Semiconductor's naming convention | Select SMBJ130CA if dual-sourcing from alternate Taiwan Semiconductor production lots is required |
| SMCJ130CA | Higher PPK (1500 W), larger DO-214AB (SMC) package, RθJA = 35 °C/W - physically incompatible footprint | Used where higher surge energy tolerance is needed (e.g., main battery inputs), but requires PCB redesign | Choose SMCJ130CA only when 600 W is insufficient and layout revision is acceptable |
Compared with SMBJ130CH, SMBJ130CA offers identical electrical performance and drop-in compatibility, while SMCJ130CA provides 2.5× higher surge capacity at the cost of larger size and non-interchangeable mounting - making SMBJ130CH optimal for space-constrained 600 W protection tasks.

FAQ
What does the 'CH' suffix indicate in SMBJ130CH?
The 'CH' suffix in SMBJ130CH denotes a bidirectional TVS diode variant within Taiwan Semiconductor's SMBJH series. It confirms symmetrical clamping behavior for both positive and negative transients, distinguishing it from unidirectional 'H' versions. SMBJ130CH is fully specified for bipolar operation per datasheet Table on page 3, with identical VBR min/max and VC values in either direction - a key requirement for protecting AC-coupled or floating DC lines where polarity is undefined.
Is SMBJ130CH compatible with lead-free reflow soldering processes?
Yes, SMBJ130CH is compatible with standard lead-free reflow soldering. It is rated MSL Level 1 per J-STD-020, meaning it can withstand multiple reflow cycles without baking or moisture sensitivity concerns. The matte tin-plated leads meet J-STD-002 solderability requirements, and the DO-214AA (SMB) package uses UL 94V-0 compliant molding compound - ensuring reliable joint formation and mechanical stability under JEDEC-standard peak temperatures up to 260 °C.
How does SMBJ130CH perform under repeated surge stress?
SMBJ130CH is rated for non-repetitive surges per the 10/1000 µs waveform, but its glass-passivated junction and thermal design support limited repetitive operation. Derating curves (Fig. 2 in datasheet) show 50% PPK capability at 70 °C ambient; sustained repetition requires verifying duty cycle and average power dissipation. For applications with frequent transients (e.g., motor drives), pairing SMBJ130CH with upstream current limiting or thermal monitoring is recommended to maintain long-term reliability.
Does SMBJ130CH meet ISO 16750-2 for automotive environmental testing?
SMBJ130CH is explicitly validated to ISO 7637-2 (Pulse 1, 2a, 2b, 3a, 3b) for electrical transient immunity, which forms the core surge test basis for ISO 16750-2. While ISO 16750-2 covers broader environmental conditions (temperature, vibration, corrosion), the device's AEC-Q101 qualification - including high-temperature reverse bias, temperature cycling, and humidity testing - confirms its suitability for full ISO 16750-2-compliant automotive modules when properly integrated into a system-level design.
Can SMBJ130CH be used in place of a unidirectional SMBJ130H?
No - SMBJ130CH and SMBJ130H are not interchangeable without circuit review. SMBJ130H is unidirectional (anode-to-cathode conduction only) and clamps only negative transients when installed with correct polarity; SMBJ130CH clamps both polarities symmetrically. Replacing SMBJ130H with SMBJ130CH eliminates polarity constraints but may alter leakage paths or ground reference behavior in DC-biased circuits. Always verify schematic topology and transient polarity assumptions before substitution.
