Product details
Overview
SMCJ130-E3/9AT from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for robust overvoltage protection of power rails and signal lines. It features a 130 V standoff voltage (VWM), 144–159 V breakdown range (VBR), 209 V clamping voltage (VC) at 7.2 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) capability with 10/1000 µs waveform.
For engineers reviewing the SMCJ130-E3/9AT datasheet, SMCJ130-E3/9AT pinout, SMCJ130-E3/9AT application, or SMCJ130-E3/9AT equivalent, this device is selected for high-energy surge suppression in automotive power modules, industrial motor drives, and telecom DC input stages where fast response (<1 ns), low clamping ratio, and AEC-Q101 qualification are required.
Technical Context
The SMCJ130-E3/9AT operates as a silicon avalanche diode that enters breakdown when reverse voltage exceeds its VBR threshold, diverting surge current away from protected circuitry. Its glass-passivated junction ensures stable leakage performance and long-term reliability under repetitive transients.
Designed for unidirectional operation, it exhibits forward conduction only during positive polarity surges on the anode side; polarity is marked by a cathode band. Thermal resistance is 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-lead), requiring minimum 8.0 mm × 8.0 mm copper pads per terminal for rated PPPM derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 130 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC/AC rail margin. |
| VBR (Breakdown Voltage) | 144–159 V at 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 209 V at IPPM = 7.2 A - Peak voltage seen by protected load during 10/1000 µs surge; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 1500 W - Maximum single-event surge energy absorption capability under standard waveform; enables IEC 61000-4-5 Level 4 compliance. |
| ID (Reverse Leakage) | 1.0 µA max at VWM - Ultra-low leakage preserves system efficiency and prevents false triggering in high-impedance circuits. |
| TJ max. | 150 °C - Maximum junction temperature rating; supports operation in under-hood automotive and industrial environments. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22 standards. |
Pinout & Package
Package: DO-214AB (SMCJ), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode identified by molded band on one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to ground or low-side return path; conducts only during positive surges relative to cathode. |
| Cathode | Current exit point during reverse breakdown | Connected to protected line (e.g., 12 V rail); clamps voltage by shunting surge current to ground when V > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Low incremental surge resistance | Enables tighter clamping (VC/VBR ≈ 1.45) and lower let-through energy versus competing TVS devices. |
| Glass passivated chip junction | Ensures stable VBR tolerance and low leakage drift across temperature (-55 °C to +150 °C). |
| MSL Level 1 (J-STD-020) | Allows unlimited floor life and reflow up to 260 °C peak without preconditioning-ideal for high-volume SMT assembly. |
| AEC-Q101 qualification | Validates suitability for automotive powertrain, body electronics, and ADAS subsystems requiring zero-defect reliability. |
| RoHS-compliant (E3 suffix) | Meets EU Directive 2011/65/EU; no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE. |
Applications
| Automotive Power Input Protection | Industrial DC Motor Drive Inputs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130A-E3/61T | Lower PPPM (400 W), smaller SMA package (DO-214AC), higher VC (219 V at 2.9 A), same VWM/VBR range. | Targeted for space-constrained consumer PCBs with lower surge exposure (IEC 61000-4-2/4-4), not automotive or industrial mains-connected systems. | Select when board area is critical and surge threat level is moderate; verify thermal pad layout compatibility. |
| SMCJ130AHE3/9AT | Identical electrical specs and package, but AEC-Q101 qualified (HE3 suffix) and JESD201 Class 2 whisker-tested. | Required for automotive safety-critical modules (e.g., ADAS camera power) where extended reliability validation is mandated. | Choose for automotive OEM programs needing full AEC-Q101 documentation traceability and enhanced metallurgical robustness. |
Compared with SMCJ130-E3/9AT, SMAJ130A-E3/61T trades surge capacity for footprint reduction, while SMCJ130AHE3/9AT adds automotive qualification without altering electrical behavior-making the latter a drop-in upgrade for AEC-Q101 compliance.

FAQ
What is the clamping voltage of SMCJ130-E3/9AT at its rated peak pulse current?
The SMCJ130-E3/9AT has a maximum clamping voltage (VC) of 209 V when subjected to its rated peak pulse current (IPPM) of 7.2 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events.
Is SMCJ130-E3/9AT suitable for automotive applications?
Yes, SMCJ130-E3/9AT is RoHS-compliant and manufactured to Vishay's commercial-grade specifications. While it shares the same DO-214AB package and electrical characteristics as AEC-Q101-qualified variants like SMCJ130AHE3/9AT, the E3 suffix indicates commercial qualification-not automotive. For automotive use, specify the HE3 variant.
What does the "9AT" suffix mean in SMCJ130-E3/9AT?
The "9AT" suffix denotes the preferred packaging configuration: 3500 units per 13-inch diameter plastic tape-and-reel. This format supports high-speed automated pick-and-place assembly and is compatible with standard SMT feeders used in volume manufacturing.
How does the thermal performance of SMCJ130-E3/9AT affect its surge rating?
The SMCJ130-E3/9AT has a junction-to-ambient thermal resistance (RθJA) of 75 °C/W. Its 1500 W PPPM rating assumes mounting on 8.0 mm × 8.0 mm copper pads per terminal; derating applies above TA = 25 °C per Figure 2 in the datasheet. Without adequate copper area, sustained surges may exceed TJ max. of 150 °C.
Can SMCJ130-E3/9AT be used in bidirectional configurations?
No, SMCJ130-E3/9AT is a unidirectional TVS diode, indicated by the "A" (not "CA") suffix. Bidirectional operation requires the CA variant (e.g., SMCJ130CA), which lacks polarity marking and provides symmetrical clamping in both directions. Using SMCJ130-E3/9AT in reverse-biased AC applications risks permanent failure.
