Product details
Overview
1.5SMC130A-E3/9AT from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 130 V breakdown voltage (VBR = 124–137 V), 179 V maximum clamping voltage (VC) at 8.4 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and DC power rail protection.
For engineers reviewing the 1.5SMC130A-E3/9AT datasheet, 1.5SMC130A-E3/9AT pinout, 1.5SMC130A-E3/9AT application, or 1.5SMC130A-E3/9AT equivalent, key selection criteria include its unidirectional polarity, SMC (DO-214AB) surface-mount package, 111 V stand-off voltage (VWM), <1 µA reverse leakage at VWM, and AEC-Q101 qualification eligibility via HE3/HM3 variants.
Technical Context
This TVS diode operates as a clamping device that transitions from high-impedance standby to low-impedance conduction when transient voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and fast response time (<1.0 ns), enabling effective suppression of ESD, lightning-induced surges, and inductive switching spikes.
Thermal performance is defined by RθJA = 75 °C/W and RθJL = 15 °C/W, with derating above TA = 25 °C per Figure 2. The device supports repetitive surge duty cycle ≤0.01% and withstands 200 A non-repetitive forward surge (8.3 ms half-sine) - critical for protecting downstream MOSFETs and ICs in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 124–137 V at 1.0 mA test current - defines precise turn-on threshold for reliable clamping onset |
| Stand-off Voltage VWM | 111 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| Clamping Voltage VC | 179 V at 8.4 A IPPM - limits voltage seen by protected circuit during 10/1000 µs transients |

|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor front-ends (e.g., pressure, temperature) from load dump and ESD in vehicle ECUs. IC Role / Device Role / Timing Role: Unidirectional clamping element placed between sensor signal line and chassis ground. Use Value: Limits transient voltage to ≤179 V during 10/1000 µs surges, preserving signal integrity and preventing damage to 5 V or 3.3 V interface ICs. |
Use Scenario: Safeguarding 24 V digital input channels in programmable logic controllers against field-wiring induced surges and relay coil flyback. IC Role / Device Role / Timing Role: Primary overvoltage clamp on input terminal block, upstream of optocoupler or Schmitt trigger input stage. Use Value: Absorbs up to 1500 W surge energy while maintaining <1 µA leakage at 111 V nominal, ensuring no false triggering during steady-state operation. |
| DC Power Rail Protection (12–48 V) | Telecom Line Card Surge Suppression |
Use Scenario: Secondary protection on switched-mode power supply outputs feeding sensitive FPGA or MCU rails in industrial edge devices. IC Role / Device Role / Timing Role: Fast-response shunt device parallel to bulk capacitance, clamping overshoot from regulator instability or hot-swap events. Use Value: Clamps 12 V–48 V rail transients to safe levels within nanoseconds, complementing primary MOV or GDT-based front-end protection. |
Use Scenario: Protecting Ethernet PHY or PoE controller inputs on telecom line cards exposed to lightning-induced surges on twisted-pair cabling. IC Role / Device Role / Timing Role: Point-of-entry unidirectional TVS on differential pair or bias feed line, referenced to system ground. Use Value: Provides sub-200 V clamping at 8.4 A with minimal capacitance - avoids signal distortion in 10/100/1000BASE-T data paths. |
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-E3/52T | Lower PPPM (600 W), SMB package (smaller footprint, higher RθJA = 90 °C/W) | Suitable for space-constrained consumer electronics; not recommended for automotive or high-reliability industrial use | Select when board area is critical and surge energy is ≤600 W; verify thermal margin with reduced copper pad area |
| 1.5KE130A | Through-hole DO-201 package, same VBR/VC specs but lower surge repetition capability and no MSL-1 rating | Used in legacy designs or prototyping where manual assembly or socketing is preferred | Choose only for non-automated production or repair scenarios; avoid for new SMT designs requiring AEC-Q101 traceability |
Compared with 1.5SMC130A-E3/9AT, SMBJ130A-E3/52T offers smaller size but sacrifices 60% peak power handling and thermal robustness, while 1.5KE130A provides identical electrical specs in through-hole form - making the 1.5SMC130A-E3/9AT optimal for automated, high-reliability SMT deployments demanding 1500 W surge immunity and RoHS compliance.

FAQ
What is the clamping voltage of the 1.5SMC130A-E3/9AT under a 10/1000 µs surge?
The 1.5SMC130A-E3/9AT clamps to a maximum of 179 V at 8.4 A peak pulse current (IPPM) when subjected to a 10/1000 µs waveform. This value is measured per Figure 1 and Table on page 2 of Vishay document 88303 and represents the upper limit of voltage imposed on the protected circuit during standardized surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the 1.5SMC130A-E3/9AT RoHS-compliant and lead-free?
Yes, the 1.5SMC130A-E3/9AT carries the "E3" suffix, indicating full RoHS compliance and lead-free construction with matte tin-plated terminals. It meets JESD201 Class 2 whisker resistance requirements and is rated for peak reflow temperatures up to 260 °C (MSL Level 1), making it suitable for modern lead-free SMT assembly processes without compromise to reliability.
Does the 1.5SMC130A-E3/9AT have AEC-Q101 qualification?
The base 1.5SMC130A-E3/9AT is not AEC-Q101 qualified; however, Vishay offers AEC-Q101-compliant versions under ordering codes such as 1.5SMC130AHE3_A/I (with "HE3" suffix). These variants undergo extended stress testing per AEC-Q101 and are designated for automotive applications - the E3/9AT variant remains commercial-grade but shares identical electrical and thermal specifications.
What is the reverse leakage current of the 1.5SMC130A-E3/9AT at its stand-off voltage?
At its rated stand-off voltage (VWM) of 111 V and TA = 25 °C, the 1.5SMC130A-E3/9AT exhibits a maximum reverse leakage current (ID) of 1.0 µA. This low leakage ensures minimal power loss and prevents false triggering in high-impedance circuits such as sensor bias networks or precision reference paths.
How does the 1.5SMC130A-E3/9AT differ from bidirectional TVS diodes like 1.5SMC130CA?
The 1.5SMC130A-E3/9AT is unidirectional and functions as a single-polarity clamp - conducting only during reverse overvoltage events, with polarity marked by a cathode band. In contrast, 1.5SMC130CA is bidirectional and symmetrical, suppressing transients in both directions without polarity sensitivity - making it suitable for AC lines or differential signals, whereas the 1.5SMC130A-E3/9AT is optimized for DC rail and single-ended signal protection.
