Product details
Overview
1.5SMC13A-E3/9AT from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on power and signal lines. It features 13 V breakdown voltage (VBR min/max = 12.4–13.7 V at 1.0 mA), 11.1 V stand-off voltage (VWM), 18.2 V maximum clamping voltage (VC) at 82.4 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the 1.5SMC13A-E3/9AT datasheet, 1.5SMC13A-E3/9AT pinout, 1.5SMC13A-E3/9AT application, or 1.5SMC13A-E3/9AT equivalent, this page delivers verified electrical parameters, thermal derating behavior, RoHS-compliant packaging details, and real-world protection use cases - all confirmed from Vishay's official 1.5SMC Series specification document (Rev. 09-Mar-2026, Doc. #88303).
Technical Context
The 1.5SMC13A-E3/9AT operates as a unidirectional avalanche diode with glass-passivated junction, delivering fast response (<1 ps) to ESD and lightning-induced surges. Its clamping action begins at VWM = 11.1 V and fully engages by VC = 18.2 V under 82.4 A (10/1000 µs), limiting energy dissipation while maintaining low incremental surge resistance.
Thermally, it exhibits RθJA = 75 °C/W (junction-to-ambient, mounted on 8.0 mm × 8.0 mm copper pads) and RθJL = 15 °C/W (junction-to-leads), enabling reliable operation up to TJ = +150 °C. It meets J-STD-020 MSL Level 1 and is RoHS-compliant per suffix -E3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at IT = 1.0 mA - defines precise avalanche onset threshold for consistent overvoltage triggering |
| VWM | 11.1 V - maximum continuous reverse operating voltage before leakage exceeds 5.0 µA |
| VC @ IPPM | 18.2 V at 82.4 A (10/1000 µs) - clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 1500 W - peak transient power handling capability without failure under standardized surge waveform |
| IFSM | 200 A (8.3 ms half-sine) - surge current tolerance for unidirectional forward conduction events |
| TJ range | –65 °C to +150 °C - operational and storage temperature envelope compatible with under-hood automotive environments |
| Package | SMC (DO-214AB) - surface-mount outline with 0.305" × 0.320" footprint, matte tin-plated leads, UL 94 V-0 molding compound |

| Cathode | Current exit terminal in forward bias; marked with band | Connected to protected line (e.g., 12 V supply rail) - clamps to anode when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power | Enables robust protection against IEC 61000-4-5 Level 4 (4 kV surge) on 12 V DC rails without derating |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: 12 V battery-supplied control module exposed to load-dump transients (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VBAT and GND to clamp positive-going surges above 13 V. Use Value: Limits voltage seen by MCU and CAN transceiver to ≤18.2 V, preventing latch-up or gate oxide damage during 1500 W transient events. |
Use Scenario: 4–20 mA current-loop sensor interface in factory automation PLC input card, subject to field-wiring ESD and inductive kickback. IC Role / Device Role / Timing Role: TVS connected across sensor input terminals to shunt transients before they reach op-amp front-end. Use Value: Clamps fast transients (<1 ns rise) to safe levels while adding only 15 pF junction capacitance - preserving signal integrity up to 1 MHz bandwidth. |
| DC-DC Converter Input Protection | Consumer USB Power Port Protection |
|
Use Scenario: 24 V input to isolated flyback converter powering PoE-powered devices, vulnerable to induced surges from adjacent AC wiring. IC Role / Device Role / Timing Role: Primary-side TVS placed upstream of input filter capacitor to absorb energy before EMI filter saturation. Use Value: Handles repetitive 10/1000 µs surges at 0.01 % duty cycle without degradation - supports continuous operation in harsh industrial settings. |
Use Scenario: 5 V USB Type-A port on smart speaker, exposed to human-body-model (HBM) ESD and cable discharge events. IC Role / Device Role / Timing Role: Unidirectional TVS tied between VUSB and GND, with cathode to VUSB, to suppress positive surges. Use Value: Achieves <5 µA leakage at 5 V (well below USB spec limit), ensuring no impact on standby current or enumeration timing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A-E3/52T | Lower PPPM = 600 W; same VBR (12.4–13.7 V); SMB package (smaller footprint, higher RθJA = 85 °C/W) | Best suited for space-constrained consumer electronics where surge severity is limited to IEC 61000-4-2 Level 4 (8 kV contact) | Select when board area is critical and peak surge energy is ≤600 W - not suitable for ISO 7637-2 load-dump scenarios. |
| 1.5KE13A-T | Through-hole TO-204AA (DO-41); identical VBR/VC specs but PPPM = 1500 W; higher IFSM = 225 A | Used in legacy industrial power supplies where through-hole assembly remains standard | Choose for repair/refurbishment of existing through-hole designs or where mechanical robustness outweighs SMT density benefits. |
Compared with SMBJ13A-E3/52T and 1.5KE13A-T, the 1.5SMC13A-E3/9AT delivers identical clamping performance in a surface-mount SMC package optimized for automated placement, thermal performance (RθJA = 75 °C/W), and high-reliability automotive-grade variants - making it the preferred choice for new SMT designs requiring full 1500 W surge immunity.

FAQ
What is the maximum clamping voltage of the 1.5SMC13A-E3/9AT under a 10/1000 µs surge?
The 1.5SMC13A-E3/9AT clamps to a maximum of 18.2 V when subjected to its rated peak pulse current of 82.4 A with a 10/1000 µs waveform. This value is measured per Figure 1 in Vishay's official datasheet (Doc. #88303) and represents the upper voltage limit imposed on protected circuitry during worst-case transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the 1.5SMC13A-E3/9AT RoHS-compliant and halogen-free?
Yes, the 1.5SMC13A-E3/9AT carries the -E3 suffix, indicating it is RoHS-compliant per EU Directive 2011/65/EU and meets Vishay's commercial-grade material specifications. It is not halogen-free; for halogen-free compliance, the -M3 variant (e.g., 1.5SMC13A-M3/9AT) must be selected - both share identical electrical characteristics and SMC packaging.
Does the 1.5SMC13A-E3/9AT have AEC-Q101 qualification?
No, the 1.5SMC13A-E3/9AT is not AEC-Q101 qualified. That qualification applies only to variants with HE3 or HM3 suffixes (e.g., 1.5SMC13AHE3_A/I). The -E3/9AT version is commercial-grade and intended for industrial and consumer applications where automotive stress testing is not required - though its construction and thermal specs support extended temperature operation up to +150 °C.
What is the reverse leakage current of the 1.5SMC13A-E3/9AT at its stand-off voltage?
At VWM = 11.1 V and TA = 25 °C, the 1.5SMC13A-E3/9AT exhibits a maximum reverse leakage current (ID) of 5.0 µA. This low leakage ensures minimal power loss in always-on systems and avoids false triggering in high-impedance sensing circuits - verified per the Electrical Characteristics table in Vishay's 1.5SMC Series datasheet (Rev. 09-Mar-2026).
Can the 1.5SMC13A-E3/9AT be used in bidirectional configurations?
No, the 1.5SMC13A-E3/9AT is strictly unidirectional. Bidirectional variants use the "CA" suffix (e.g., 1.5SMC13CA-E3/9AT) and feature symmetrical breakdown in both polarities. Using the unidirectional 1.5SMC13A-E3/9AT in reverse-biased mode beyond its VWM risks premature breakdown and unreliable clamping - always match device polarity to system grounding architecture.
