Product details
Overview
SMDJ130A from Alpha & Omega Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and signal interfaces. It features a 130 V reverse standoff voltage (VRWM), 144–159 V breakdown voltage (VBR) at 1 mA, 209 V maximum clamping voltage (VC) at 14.4 A peak pulse current, and 3000 W peak pulse power rating on 10/1000 µs waveform - deployed in industrial motor drives to protect IGBT gate drivers from inductive switching transients.
For engineers reviewing the SMDJ130A datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage margin relative to protected IC's absolute maximum rating, thermal resistance (RθJA = 75 °C/W), unidirectional polarity confirmation, and DO-214AB package compatibility with automated SMT assembly.
Technical Context
The SMDJ130A operates as a silicon avalanche diode optimized for fast transient suppression. Its glass-passivated junction enables sub-1 ps response time from 0 V to breakdown, and its low-profile DO-214AB package supports surface-mount board space optimization while maintaining 150 °C maximum junction temperature operation.
It delivers 3000 W peak pulse power handling under standardized 10/1000 µs waveform conditions when mounted on 8.0 mm × 8.0 mm copper pads, with 2.0 µA maximum reverse leakage at VRWM and a typical temperature coefficient of 0.1% × VBR per °C change.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 130 V - Maximum continuous reverse operating voltage before clamping begins; sets upper limit for protected circuit's steady-state DC rail. |
| VBR @ IT=1 mA | 144–159 V - Confirmed breakdown range ensures reliable turn-on during overvoltage events without premature conduction. |
| VC @ IPPM | 209 V - Clamping voltage at 14.4 A peak pulse current; defines worst-case voltage seen by downstream components during surge. |
| PPPM (10/1000 µs) | 3000 W - Peak surge energy absorption capability; determines survivability against lightning-induced or ESD-coupled transients. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance; used to calculate temperature rise under sustained power dissipation or repetitive pulses. |
| IR @ VRWM | 2.0 µA - Reverse leakage current at rated standoff voltage; negligible loading effect on high-impedance sensing or bias networks. |
| Polarity | Unidirectional - Cathode-banded device requiring correct orientation in series with positive supply rails for DC line protection. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC130A (Littelfuse) | Same DO-214AB package, identical VRWM (130 V), but higher VC = 219 V at same IPPM; RθJA = 80 °C/W. | Marginally lower clamping performance; may require larger copper area for thermal management in high-duty-cycle environments. | Select SAC130A only if legacy design uses Littelfuse footprint and thermal derating allows 10 V higher clamping. |
| 1.5KE130A (ON Semiconductor) | Through-hole DO-201 package; same electrical specs but incompatible mounting; RθJA = 100 °C/W. | Not suitable for new SMT designs; requires PCB redesign and manual assembly; inferior thermal performance. | Choose 1.5KE130A only for through-hole repair or legacy board rework where SMT is unavailable. |
Compared with SAC130A and 1.5KE130A, the SMDJ130A offers superior thermal performance (RθJA = 75 °C/W vs. 80/100 °C/W) and tighter clamping (209 V vs. 219 V), making it preferred for high-density, thermally constrained SMT layouts in industrial and automotive power systems.

FAQ
What is the maximum clamping voltage of the SMDJ130A under standard test conditions?
The SMDJ130A has a maximum clamping voltage (VC) of 209 V when subjected to its rated peak pulse current (IPPM = 14.4 A) on a 10/1000 µs waveform. This value is measured with the device mounted on 8.0 mm × 8.0 mm copper pads per terminal and represents the upper voltage limit imposed on protected circuitry during surge events. The SMDJ130A maintains this clamping performance across its specified operating junction temperature range of –55 °C to +150 °C.
Is the SMDJ130A unidirectional or bidirectional, and how is polarity identified?
The SMDJ130A is a unidirectional TVS diode, indicated by the "A" suffix and marked with a cathode band on the DO-214AB package. Polarity is confirmed by the color band denoting the cathode terminal, which must be connected toward the protected DC rail or signal line, while the anode connects to ground or return. Bidirectional variants use the "CA" suffix (e.g., SMDJ130CA), which are electrically distinct and not interchangeable with the SMDJ130A.
What is the thermal resistance and maximum junction temperature rating for the SMDJ130A?
The SMDJ130A has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and a maximum junction temperature (TJ max) of +150 °C. These values assume mounting on 8.0 mm × 8.0 mm copper pads per terminal. The SMDJ130A's RθJA enables effective heat dissipation in compact SMT layouts, and its 150 °C rating supports operation in high-temperature environments such as under-hood automotive or enclosed industrial enclosures.
Does the SMDJ130A meet lead-free and environmental compliance standards?
Yes, the SMDJ130A is a RoHS-compliant, halogen-free "Green Product" per AOS policy, featuring matte tin lead-free plating and UL 94V-0 flammability-rated plastic encapsulation. It meets J-STD-020 MSL Level 1 requirements for moisture sensitivity and is qualified for lead-free reflow up to 260 °C peak temperature. The SMDJ130A carries AOS's green product designation, confirming reduced halogen content and full compliance with EU RoHS Directive 2011/65/EU.
What is the reverse leakage current specification for the SMDJ130A at its rated standoff voltage?
The SMDJ130A exhibits a maximum reverse leakage current (IR) of 2.0 µA at its rated reverse standoff voltage (VRWM = 130 V) and ambient temperature of 25 °C. This low leakage ensures minimal power loss and negligible loading on high-impedance circuits such as sensor bias networks or precision reference paths. The SMDJ130A maintains this leakage performance across its full operating temperature range, supporting stable operation in battery-powered or energy-sensitive applications.
