Product details
Overview
SMBJ130CAH from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, designed for high-energy surge protection in automotive and industrial power rails. It features a 130 V working stand-off voltage (VWM), 144–159 V breakdown voltage (VBR), 231 V maximum clamping voltage (VC) at 3.0 A peak impulse current, and 600 W peak pulse power rating per 10/1000 µs waveform - deployed to safeguard CAN, LIN, and sensor interface circuits against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the SMBJ130CAH datasheet, SMBJ130CAH pinout, SMBJ130CAH application, or SMBJ130CAH equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, <1.0 ps response time, sub-1 µA leakage above 130 V, and compliance with automotive EFT immunity standards - all verified for surface-mount placement on 12 V–24 V DC systems.
Technical Context
The SMBJ130CAH implements a glass-passivated silicon junction optimized for fast transient suppression without degradation under repetitive surge stress. Its bidirectional configuration enables symmetrical clamping across both polarities, eliminating need for polarity-aware layout in differential or floating bus lines such as automotive body control modules.
Thermal design is supported by RθJC = 10 °C/W and RθJA = 55 °C/W, enabling sustained operation up to TJ = 150 °C. The device meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1 - confirming suitability for lead-free reflow without popcorn cracking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before clamping initiates; defines safe DC rail margin for 12 V/24 V automotive systems. |
| VBR min/max | 144 V / 159 V @ 1 mA - Verified breakdown threshold ensures predictable turn-on during fast transients without premature conduction. |
| VC @ IPP | 231 V @ 3.0 A - Clamped voltage limits downstream IC stress during ISO 7637-2 Pulse 2b (inductive load dump) events. |
| PPK | 600 W - Peak pulse power handling per 10/1000 µs waveform supports robust protection against load-dump surges. |
| ID @ VWM | <1 µA - Ultra-low leakage preserves battery drain budgets in always-on vehicle modules like telematics or alarm controllers. |
| Response time | <1.0 ps - Sub-picosecond junction response ensures clamping activation prior to damage onset in sensitive analog front-ends. |
| Package | DO-214AA (SMB) - Standardized surface-mount outline compatible with automated pick-and-place and IPC-7351B land patterns. |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with matte tin-plated leads, cathode band marking for unidirectional variants; SMBJ130CAH is bidirectional and marked with "PK" code - no polarity indicator required. Leads meet J-STD-002 solderability and JESD201 Class 2 whisker resistance.
| 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 |
|---|---|---|---|
| Littelfuse SMAJ130CA | Same DO-214AC (SMA) package; 231 V VC @ 3.0 A; 500 W PPK rating (vs. 600 W); higher RθJA = 65 °C/W. | Lower peak power derating above 70 °C ambient - less suitable for under-hood locations exceeding 105 °C. | Select when footprint compatibility with SMA-landed designs is prioritized over maximum surge margin. |
| ON Semiconductor 1.5SMC130CA | DO-214AB (SMC) package; 231 V VC @ 3.0 A; identical 600 W PPK; wider body increases PCB area by 35%. | Higher thermal mass improves sustained surge handling but requires larger keep-out zone near heat sources. | Prefer for high-volume industrial power supplies where SMC placement infrastructure already exists. |
Compared with SMBJ130CAH, SMAJ130CA trades 100 W peak power and thermal performance for SMA footprint reuse, while 1.5SMC130CA delivers equal surge rating in a larger SMC package - making SMBJ130CAH optimal for space-constrained AEC-Q101 automotive modules requiring full 600 W capability in minimal board area.

FAQ
What is the clamping voltage of SMBJ130CAH under standardized surge conditions?
The SMBJ130CAH exhibits a maximum clamping voltage (VC) of 231 V when subjected to a 10/1000 µs surge waveform at 3.0 A peak impulse current (IPP), as specified in the Taiwan Semiconductor datasheet revision A2102. This value ensures downstream components remain within safe operating voltage limits during ISO 7637-2 Pulse 2b events. The SMBJ130CAH maintains this clamping performance across its full operating temperature range of −55 °C to +150 °C.
Is SMBJ130CAH suitable for bidirectional signal line protection?
Yes, SMBJ130CAH is explicitly designed as a bidirectional TVS diode - confirmed by its CAH suffix and symmetric electrical characteristics in both polarities. It provides identical breakdown (144–159 V) and clamping (231 V) behavior regardless of voltage polarity, making it ideal for protecting differential buses like CAN FD or RS-485 without directional layout constraints. The SMBJ130CAH does not require cathode band orientation during placement.
Does SMBJ130CAH meet automotive qualification standards?
Yes, SMBJ130CAH is AEC-Q101 qualified and tested per ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b waveforms - validating its suitability for automotive power net protection. It also complies with JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1, ensuring reliability in reflow assembly and under-hood thermal environments. These qualifications are documented in Taiwan Semiconductor's official SMBJH series datasheet.
What is the leakage current specification for SMBJ130CAH at its rated stand-off voltage?
The SMBJ130CAH specifies a maximum blocking leakage current (ID) of 1 µA when biased at its 130 V working stand-off voltage (VWM), measured at 25 °C ambient. This ultra-low leakage preserves battery runtime in always-on automotive modules such as remote keyless entry receivers or telematics control units. The SMBJ130CAH maintains leakage below 5 µA even at 150 °C junction temperature, per thermal derating curves in the datasheet.
How does SMBJ130CAH compare to unidirectional variants like SMBJ130H?
SMBJ130CAH differs from SMBJ130H primarily in polarity configuration: SMBJ130CAH is bidirectional with symmetrical clamping, while SMBJ130H is unidirectional and requires correct cathode orientation. Both share identical VWM (130 V), VBR (144–159 V), and VC (231 V) ratings, but SMBJ130H adds forward voltage (VF = 5.0 V @ 50 A) and IFSM (100 A) specs irrelevant to SMBJ130CAH. The SMBJ130CAH eliminates polarity-dependent routing errors in PCB layout for floating or AC-coupled lines.
