Product details
Overview
SMBJ130 from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 130 V working stand-off voltage (VWM), 144–176 V breakdown voltage (VBR) at 1 mA, 2.7 A peak pulse current (IPP), 231 V maximum clamping voltage (VC) at IPP, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive power supply inputs and industrial I/O interfaces.
For engineers reviewing the SMBJ130 datasheet, SMBJ130 pinout, SMBJ130 application, or SMBJ130 equivalent, key selection criteria include clamping voltage margin vs. protected IC's absolute maximum rating, leakage current at operating voltage, thermal derating above 25°C ambient, and DO-214AA (SMB) package compatibility with automated SMT assembly.
Technical Context
The SMBJ130 operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its specified VBR range (144–176 V) to clamp transients by shunting surge current to ground. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 µA at 130 V).
It complies with ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive transient immunity and is rated for junction temperatures from –55°C to +150°C. Thermal resistance is 10°C/W (junction-to-case) and 55°C/W (junction-to-ambient), supporting reliable operation under sustained power dissipation up to 3 W at 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin. |
| VBR @ IT = 1 mA | 144–176 V - Breakdown voltage range confirming robust overvoltage threshold with tight tolerance. |
| VC @ IPP = 2.7 A | 231 V - Clamped voltage during 10/1000 µs surge; determines maximum stress on downstream ICs. |

Applications
| Automotive Power Input Protection | Industrial PLC Digital I/O Protection |
|---|---|
Use Scenario: 12 V/24 V battery-fed ECU power input subjected to load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp surges exceeding 130 V. Use Value: Limits peak voltage to ≤231 V during 600 W transients, protecting LDOs, microcontrollers, and CAN transceivers from destructive overvoltage. |
Use Scenario: 24 V digital input channel in programmable logic controller exposed to field-wiring ESD and inductive kickback from solenoid coils. IC Role / Device Role / Timing Role: Standoff protection device mounted at connector entry point, upstream of optocoupler or Schmitt trigger input. Use Value: Sub-µA leakage preserves high-impedance sensing accuracy; 2.7 A IPP handles repetitive 10/1000 µs transients without degradation. |
| LED Driver Supply Rail Protection | Telecom Line Interface Protection |
Use Scenario: Constant-current LED driver board powered from 48 V telecom supply, vulnerable to hot-swap transients and lightning-induced surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main DC input, coordinated with upstream fuse and downstream ceramic filtering. Use Value: 231 V clamping voltage provides ≥100 V margin above 130 V VWM, ensuring driver ICs (e.g., LM3409) remain within absolute max ratings. |
Use Scenario: RS-485 transceiver interface on outdoor base station equipment subject to induced surges from nearby lightning strikes. IC Role / Device Role / Timing Role: Secondary protection stage after gas discharge tube (GDT), absorbing residual energy below 1 kV. Use Value: 600 W PPK rating enables coordination with GDT let-through energy; DO-214AA footprint allows compact layout adjacent to connector. |
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 SMAJ130A | Same VWM (130 V), slightly lower VC (224 V @ 2.7 A), identical DO-214AA package and 600 W rating. | Better clamping margin (7 V lower VC) but higher typical leakage (~1.5 µA @ VWM). | Preferred where tighter clamping is critical and leakage tolerance permits. |
| ON Semiconductor 1.5SMC130A | VWM = 130 V, VC = 226 V @ 2.7 A, same 600 W rating, but larger DO-214AB (SMC) package (7.11 × 6.22 mm vs. SMB's 4.57 × 3.94 mm). | Requires PCB layout change; higher thermal mass improves power handling at elevated ambient. | Select when board space allows larger footprint and higher thermal inertia is needed. |
Compared with SMBJ130, SMAJ130A offers improved clamping performance in identical footprint, while 1.5SMC130A trades size for enhanced thermal robustness - choice depends on layout constraints, clamping margin requirements, and thermal environment.

FAQ
What is the maximum clamping voltage of SMBJ130 under standard test conditions?
The SMBJ130 has a maximum clamping voltage (VC) of 231 V when subjected to a 10/1000 µs surge current of 2.7 A. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream ICs remain within their absolute maximum ratings. The SMBJ130 maintains this clamping performance across its specified operating temperature range.
Is SMBJ130 unidirectional or bidirectional, and how is polarity identified?
SMBJ130 is a unidirectional TVS diode, intended for DC line protection where polarity is fixed. Polarity is marked by a cathode band on the DO-214AA (SMB) package - the banded end connects to the protected line (e.g., 12 V rail), and the non-banded end connects to ground. Bidirectional variants require "C" or "CA" suffixes (e.g., SMBJ130C), which are distinct part numbers not interchangeable with SMBJ130.
Does SMBJ130 meet automotive transient immunity standards?
Yes, SMBJ130 meets ISO 7637-2 requirements for Pulses 1, 2a, 2b, 3a, and 3b - covering common automotive transients including load dump, battery disconnection, and inductive switching noise. Its 600 W peak pulse power rating and controlled clamping behavior make it suitable for ECU power inputs, body control modules, and infotainment system interfaces per OEM specifications.
What is the leakage current specification for SMBJ130 at its working voltage?
SMBJ130 exhibits a maximum blocking leakage current (ID) of 1 µA when biased at its 130 V working stand-off voltage (VWM), tested at 25°C. This ultra-low leakage preserves signal integrity in high-impedance monitoring circuits and minimizes standby power loss in always-on automotive subsystems - a key differentiator versus higher-leakage alternatives.
Can SMBJ130 be used in place of SMBJ130A?
No - SMBJ130 and SMBJ130A are not interchangeable. SMBJ130A has tighter VBR tolerance (144–159 V vs. 144–176 V) and lower clamping voltage (209 V vs. 231 V). While both share VWM = 130 V and DO-214AA packaging, the broader VBR range of SMBJ130 results in higher worst-case clamping, making SMBJ130A preferable where precise voltage limiting is required. Always verify design margins using the specific variant's datasheet.
