Product details
Overview
1.5SMC13A from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, designed for primary overvoltage protection of DC power rails and signal lines. It features 12.4–13.7 V breakdown voltage (VBR), 11.1 V working stand-off voltage (VWM), 18.2 V maximum clamping voltage (VC) at 86 A peak pulse current, and 1500 W peak pulse power rating - enabling robust ESD and lightning surge immunity in telecom front-ends and industrial I/O interfaces.
For engineers reviewing the 1.5SMC13A datasheet, 1.5SMC13A pinout, 1.5SMC13A application, or 1.5SMC13A equivalent, this page delivers verified electrical parameters, thermal resistance values (RθJA = 50 °C/W), ISO 7637-2 compliance status, moisture sensitivity level (MSL 1), and precise clamping behavior under 10/1000 µs surge waveforms - all critical for automotive body electronics, PoE-powered devices, and industrial sensor node design.
Technical Context
The 1.5SMC13A operates as a unidirectional avalanche diode with glass-passivated junction, delivering sub-1 ps response time and <1 µA leakage at 11.1 V. Its clamping action begins at VBR ≥12.4 V (tested at 1 mA), limiting transient energy to ≤18.2 V across 86 A peak impulse current per 10/1000 µs waveform.
Thermally, it sustains continuous operation up to +150 °C junction temperature, with RθJC = 15 °C/W enabling effective heat transfer to PCB copper. The device meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements - confirming suitability for high-reliability surface-mount assembly in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V - defines minimum and maximum voltage at which avalanche conduction initiates reliably at 1 mA test current |
| VWM | 11.1 V - maximum continuous reverse operating voltage before significant leakage occurs; sets safe DC rail margin |
| VC @ IPPM | 18.2 V at 86 A - clamped voltage during worst-case 10/1000 µs surge; determines protected circuit's maximum stress level |
| PPK | 1500 W - peak pulse power handling capability per single non-repetitive surge event |
| IR @ VWM | <1 µA - ensures negligible standby power loss and no interference with high-impedance sensing circuits |
| TJ max | +150 °C - maximum allowable junction temperature; supports operation in sealed enclosures or high-ambient industrial settings |
| RθJA | 50 °C/W - thermal resistance from junction to ambient; used to calculate temperature rise under sustained power dissipation |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, single-die unidirectional configuration with cathode band marking. Dimensions comply with JEDEC MS-013AC standard; recommended pad layout provided in Taiwan Semiconductor S2207 datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |

| Response speed | <1 ps typical enables suppression before sensitive logic or analog circuitry responds to fast-rising ESD events |
| Leakage control | <1 µA at 11.1 V prevents loading of high-impedance voltage dividers or battery-monitoring circuits |
| Automated assembly support | DO-214AB package and matte tin-plated leads meet J-STD-002 solderability and JESD201 Class 2 whisker standards |
| Environmental compliance | RoHS-compliant and halogen-free per IEC 61249-2-21 - suitable for consumer and industrial products with strict material restrictions |
Applications
| Industrial Sensor Interface | Automotive Body Control Module |
|---|---|
Use Scenario: Protecting 4–20 mA current-loop transmitters and RS-485 nodes against induced surges from nearby motor switching or relay contact bounce. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and ground, clamping transients before they reach isolated ADC or transceiver inputs. Use Value: Limits voltage excursion to ≤18.2 V during 86 A surge, preserving integrity of ±15 V supply rails and preventing latch-up in precision op-amps. |
Use Scenario: Safeguarding LIN bus lines and low-side driver outputs in door module ECUs exposed to load dump and jump-start conditions. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 12 V supply input and LIN data line, coordinated with upstream fuse and downstream LDO. Use Value: Withstands ISO 7637-2 Pulse 5a (load dump) energy while maintaining VWM = 11.1 V margin below nominal 12 V system voltage. |
| Telecom Power Input Stage | POE-Powered Endpoint |
Use Scenario: Front-end protection of AC/DC adapter inputs in DSL modems and fiber ONTs subjected to lightning-induced common-mode surges on mains lines. IC Role / Device Role / Timing Role: Secondary TVS after MOV-based primary stage, absorbing residual differential-mode transients before rectifier bridge. Use Value: 1500 W peak power rating handles residual 10/1000 µs surges not suppressed by upstream components, reducing failure rate in field-deployed units. |
Use Scenario: DC input protection on IEEE 802.3af/at powered devices (PDs) where PSE delivers up to 57 V, and accidental short-circuits generate high-current transients. IC Role / Device Role / Timing Role: Unidirectional clamp on PD input rail referenced to local ground, sized to survive repeated 86 A pulses without degradation. Use Value: Clamping at 18.2 V prevents overvoltage damage to PoE interface ICs (e.g., TPS2375x) during hot-swap or cable fault events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A (Bourns) | Same DO-214AA (SMB) package; 13 V VBR range, 1000 W PPK, higher VC = 21.5 V at 49 A | Lower peak power rating limits use in high-energy automotive load-dump scenarios | Select SMBJ13A only if board space constraints require smaller SMB footprint and surge energy remains ≤1000 W |
| 1.5KE13A (ON Semiconductor) | Through-hole DO-15 package; identical VBR/VC specs but 1500 W rating applies at 25 °C only (no derating curve provided) | Not suitable for automated SMT production; requires wave soldering or hand assembly | Choose 1.5KE13A only for legacy through-hole designs or prototyping where reflow compatibility is not required |

FAQ
What is the polarity configuration of the 1.5SMC13A?
The 1.5SMC13A is a unidirectional TVS diode, featuring anode and cathode terminals marked by a cathode band on the DO-214AB package body. It conducts in forward bias like a standard diode and clamps transients in reverse bias above its breakdown voltage - making it ideal for DC rail protection where polarity is fixed and reverse conduction must be blocked.
Does the 1.5SMC13A meet ISO 7637-2 automotive surge standards?
Yes, the 1.5SMC13A is explicitly rated to meet ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b test waveforms per Taiwan Semiconductor's S2207 datasheet. Its 1500 W peak pulse power rating and 18.2 V clamping voltage at 86 A ensure compliance with the energy and voltage limits defined in those pulses for 12 V systems.
What is the maximum junction temperature rating for the 1.5SMC13A?
The 1.5SMC13A has a maximum junction temperature (TJ) rating of +150 °C, as specified in its Absolute Maximum Ratings table. This allows reliable operation in sealed enclosures, under-hood automotive locations, or industrial environments where ambient temperatures exceed 85 °C - provided thermal design accounts for RθJA = 50 °C/W.
How does the 1.5SMC13A differ from the 1.5SMC13 variant?
The 1.5SMC13A offers tighter breakdown voltage tolerance (12.4–13.7 V) compared to the 1.5SMC13 (11.7–14.3 V), resulting in more consistent clamping onset and reduced variation in protected circuit stress levels. Both share identical package, power rating, and thermal specs - but the 'A' suffix denotes enhanced VBR uniformity for precision protection applications.
Is the 1.5SMC13A RoHS and halogen-free compliant?
Yes, the 1.5SMC13A is RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the "Features" section of Taiwan Semiconductor's S2207 datasheet.
