Product details
Overview
SMCJ130 from Taiwan Semiconductor is a unidirectional 1500W surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, with 130V working stand-off voltage (VWM), 144–176V breakdown voltage (VBR), and 231V maximum clamping voltage (VC) at 6.8A peak impulse current - designed for automotive load-dump and inductive switching protection in power supply rails.
For engineers reviewing the SMCJ130 datasheet, SMCJ130 pinout, SMCJ130 application, or SMCJ130 equivalent, key selection criteria include clamping voltage margin vs. protected IC VMAX, peak pulse current capability under ISO 7637-2 Pulse 5a, thermal derating above 25°C ambient, and unidirectional polarity marking alignment with system ground-referenced transients.
Technical Context
The SMCJ130 operates as a silicon avalanche diode that enters controlled breakdown when reverse voltage exceeds its VBR range (144–176V @ 1mA), limiting transient energy to safe levels via low-impedance conduction. Its glass-passivated junction ensures stable leakage (<1µA @ 130V) and fast response (<1.0ps rise time).
It meets ISO 7637-2 immunity requirements for Pulse 1 (inductive flyback), Pulse 2a/2b (battery disconnect), Pulse 3a/3b (capacitive coupling), and supports 200A non-repetitive forward surge (IFSM) - critical for 12V/24V automotive subsystems where load dump events exceed 100V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before clamping begins; sets upper limit for normal rail operation. |
| VBR min/max | 144 V / 176 V @ 1 mA - Confirmed breakdown threshold range; defines minimum overvoltage level triggering protection. |
| VC @ IPPM | 231 V @ 6.8 A - Clamped voltage during 10/1000 µs surge; determines maximum stress on downstream components. |
| PPK | 1500 W - Peak pulse power handling per single 1ms event; enables robust suppression of high-energy transients. |
| TJ max | +150 °C - Maximum junction temperature; supports operation in under-hood automotive environments. |
| RθJA | 55 °C/W - Junction-to-ambient thermal resistance; informs PCB copper area and heatsinking requirements for sustained surge duty. |
Pinout & Package
DO-214AB (SMC) surface-mount package with cathode band marking on one end; dual-leaded, gull-wing leadform compatible with automated placement and reflow soldering per J-STD-002. Matte tin-plated terminals meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground-reference terminal (for unidirectional configuration) | Connected to system ground or low-side return path; establishes reference for clamping action. |
| Cathode | Line-side terminal (marked with band) | Connected to protected line (e.g., battery feed); conducts avalanche current to ground during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance and <1 µA IR at VWM, critical for low-power standby circuits. |
| ISO 7637-2 compliance | Validated for Pulse 1/2a/2b/3a/3b waveforms - directly qualifies for automotive ECU and body-control module designs. |
| Fast response time | <1.0 ps from 0 V to VBR min - prevents voltage overshoot before clamping engages, protecting sensitive gate drivers and microcontrollers. |
| Moisture sensitivity level 1 | No floor-life limitation or bake requirement prior to reflow - simplifies manufacturing logistics and reduces assembly cost. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | 600W rating, lower VC (219V @ 4.5A), SMB package (smaller footprint, higher RθJA = 75°C/W) | Lower energy handling; suitable only for sub-600W surge profiles (e.g., IEC 61000-4-5 Level 3) | Select SMCJ130 for ISO 7637-2 Pulse 5a compliance; SMBJ130A only if space-constrained and peak power <600W. |
| 1.5KE130A | Through-hole DO-201 package, same 130V VWM, but slower response (>1ns), higher VC (220V @ 6.8A), no ISO 7637-2 validation | Not qualified for automotive; limited to industrial AC/DC front-end or legacy board designs | Choose SMCJ130 for surface-mount automation, automotive qualification, and faster clamping; 1.5KE130A only for through-hole retrofit or cost-sensitive non-automotive use. |
Compared with SMBJ130A and 1.5KE130A, the SMCJ130 delivers 2.5× higher peak power (1500W vs. 600W/1500W), verified ISO 7637-2 compliance, and surface-mount manufacturability - making it the preferred choice for new automotive and industrial power-rail protection designs requiring robust, validated transient immunity.

FAQ
What is the maximum clamping voltage of the SMCJ130 under standard test conditions?
The SMCJ130 has a maximum clamping voltage (VC) of 231 V when subjected to a 10/1000 µs waveform peak impulse current (IPPM) of 6.8 A. This value is measured at TA = 25°C and represents the highest voltage seen across the device during surge conduction - a critical parameter for ensuring protected ICs remain below their absolute maximum ratings. The SMCJ130 maintains this clamping performance consistently due to its glass-passivated junction and optimized die geometry.
Is the SMCJ130 suitable for automotive applications requiring ISO 7637-2 compliance?
Yes, the SMCJ130 is explicitly rated to meet ISO 7637-2 for Pulse 1, 2a, 2b, 3a, and 3b waveforms - covering common automotive transients including inductive load dump, battery disconnection, and capacitive coupling noise. Its 1500W peak power rating, fast <1.0ps response, and 130V working voltage make it appropriate for 24V commercial vehicle ECUs and body control modules. The SMCJ130 datasheet confirms this qualification without derating assumptions.
How does the SMCJ130 differ from the SMCJ130A variant?
The SMCJ130 and SMCJ130A share identical VWM (130V) and package (DO-214AB), but differ in breakdown voltage tightness and clamping performance: SMCJ130 has VBR = 144–176V and VC = 231V @ 6.8A, while SMCJ130A has tighter VBR = 144–159V and lower VC = 209V @ 7.5A. The "A" suffix denotes enhanced VBR uniformity and improved clamping ratio - beneficial where precise voltage thresholding and lower let-through voltage are required, such as in high-precision power supply monitoring circuits.
What is the thermal resistance and maximum junction temperature specification for the SMCJ130?
The SMCJ130 has a junction-to-ambient thermal resistance (RθJA) of 55°C/W and a maximum junction temperature (TJ) of +150°C. These values define its ability to dissipate surge energy without thermal runaway: at 25°C ambient, it can sustain full 1500W pulses; above 25°C, power must be derated per Fig.2 in the datasheet. The 150°C TJ rating allows reliable operation in under-hood automotive environments and enclosed industrial enclosures when mounted on ≥1 sq-in. 2-oz copper.
Does the SMCJ130 have polarity marking, and how is it oriented in circuit layout?
Yes, the SMCJ130 features a cathode band marking on the DO-214AB package - indicating the cathode terminal. In unidirectional configuration, the cathode connects to the protected line (e.g., battery rail), and the anode connects to ground. This orientation ensures avalanche conduction only during positive transients on the line. The marking aligns with JEDEC-standard polarity conventions and is visible under optical inspection; incorrect orientation results in no clamping action during reverse surges.
