Product details
Overview
1.5SMC13C from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, rated for 1500W peak pulse power, 13V breakdown voltage (min 11.7V, max 14.3V), and clamps to ≤19.0V at 82A peak impulse current. It protects DC power rails and I/O lines in telecom interfaces and industrial control inputs against ESD and lightning-induced surges.
For engineers reviewing the 1.5SMC13C datasheet, 1.5SMC13C pinout, 1.5SMC13C application, or 1.5SMC13C equivalent, key selection criteria include working stand-off voltage (10.5V), leakage current (<1µA at VWM), clamping ratio (VC/VBR ≈ 1.4–1.6), and compliance with ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive load-dump immunity.
Technical Context
The 1.5SMC13C uses a glass-passivated silicon junction optimized for fast transient response (<1.0ps), low capacitance, and stable clamping under repetitive surge stress. Its unidirectional configuration provides asymmetric protection-blocking reverse voltage up to 10.5V while clamping positive transients to 19.0V at 82A.
Thermal design relies on RθJA = 50°C/W and RθJC = 15°C/W, enabling operation from −55°C to +150°C junction temperature. The device meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1, supporting lead-free reflow assembly without preconditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 11.7V / 14.3V - defines minimum and maximum voltage at which device enters avalanche conduction under 1mA test current |
| VWM | 10.5V - maximum continuous reverse operating voltage before significant leakage begins |
| IPPM | 82A - peak impulse current the device safely clamps at 10/1000μs waveform without degradation |
| VC@IPPM | 19.0V - clamped voltage across terminals during 82A surge, determining protected circuit's maximum overvoltage exposure |
| PPK | 1500W - peak pulse power handling capability per single 10/1000μs transient, derated above 25°C ambient |
| IR@VWM | <1µA - reverse leakage at 10.5V ensures minimal standby power loss and signal integrity in high-impedance circuits |
| TJ max | +150°C - maximum junction temperature enabling reliable operation in enclosed industrial enclosures or near heat sources |
Pinout & Package

IC Role / Device Role / Timing Role: Parallel-connected TVS across bulk capacitor input to absorb residual spikes after MOV clamping. Use Value: Fast <1.0ps response captures high-frequency ringing missed by slower MOVs, reducing EMI and improving EMC margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A (Bourns) | Same DO-214AA package; 13V breakdown (12.4–13.7V), 1000W rating, higher VC = 21.5V @ 47A | Limited to lower-energy transients; not rated for ISO 7637-2 Pulse 2b | Select when space-constrained layout requires smaller SMB package and 1000W suffices |
| 1.5KE13C (ON Semiconductor) | Through-hole DO-15 package; identical 13V breakdown range and 1500W rating; VC = 19.3V @ 78A | Requires PCB through-hole mounting; unsuitable for fully SMT production | Choose for legacy designs retaining through-hole assembly or where thermal mass of axial lead improves long-duration surge handling |
Compared with 1.5SMC13C, SMBJ13A offers smaller footprint but reduced surge capacity and missing automotive qualification, while 1.5KE13C delivers equivalent protection in through-hole form-neither is pin-compatible, but both serve as functional alternatives where package or standard compliance permits substitution.

FAQ
What is the polarity configuration of the 1.5SMC13C?
The 1.5SMC13C is a unidirectional TVS diode, with cathode marked by a band on the DO-214AB package. It blocks reverse voltage up to 10.5V and clamps positive transients to 19.0V. Unlike bidirectional variants (e.g., 1.5SMC13CA), it does not conduct symmetrically-making it ideal for DC supply rail protection where polarity is fixed.
Does the 1.5SMC13C meet automotive transient immunity standards?
Yes, the 1.5SMC13C is explicitly tested and compliant with ISO 7637-2 for Pulses 1, 2a, 2b, 3a, and 3b-covering key automotive threats including load dump, supply interruption, and coupled transients. Its 1500W rating and 19.0V clamping support robust protection in BCM and sensor node designs meeting OEM requirements.
What is the maximum steady-state power dissipation for the 1.5SMC13C?
The 1.5SMC13C has a steady-state power dissipation (PD) of 6.5W at TA = 25°C. This value decreases with rising ambient temperature per the derating curve in Figure 2 of the datasheet. For continuous DC bias applications, thermal design must ensure junction temperature remains ≤150°C using the specified RθJA = 50°C/W.
How does the 1.5SMC13C differ from the 1.5SMC13CA variant?
The 1.5SMC13C is unidirectional, while 1.5SMC13CA is bidirectional-designed for AC signal lines or floating buses. The CA version has identical VBR, VWM, and PPK, but conducts in both directions and lacks polarity marking. Use 1.5SMC13C for DC rails; choose 1.5SMC13CA only when symmetrical clamping (e.g., RS-232, audio lines) is required.
Is the 1.5SMC13C compatible with lead-free reflow soldering processes?
Yes, the 1.5SMC13C is qualified for lead-free reflow per J-STD-020 Level 1 moisture sensitivity-no baking is required prior to assembly. Its matte tin-plated leads comply with J-STD-002 for solderability, and the package withstands peak temperatures up to 260°C for 10 seconds, matching standard Pb-free reflow profiles.
