Product details
Overview
1.5SMC13CA from Taiwan Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode designed for robust ESD and surge protection in DC power rails and signal lines. It features a 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 per 10/1000 µs waveform - deployed in telecom front-ends and industrial I/O interfaces.
For engineers reviewing the 1.5SMC13CA datasheet, 1.5SMC13CA pinout, 1.5SMC13CA application, or 1.5SMC13CA equivalent, key selection criteria include bidirectional clamping symmetry, sub-1 ps response time, <1 µA leakage at VWM, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, and DO-214AB (SMC) package thermal performance (RθJC = 15 °C/W).
Technical Context
The 1.5SMC13CA operates as a bipolar junction TVS diode with symmetrical avalanche breakdown in both forward and reverse directions, enabling single-device protection of AC-coupled or floating signal paths. Its glass-passivated chip junction ensures stable VBR tolerance (±5%) and low temperature coefficient (0.081 %/°C), critical for automotive and industrial environments where ambient temperature swings exceed 100 °C.
It delivers 1500 W peak pulse power handling per 10/1000 µs waveform while maintaining clamping voltage ≤18.2 V at 86 A - enabling protection of 12 V systems against load dump transients and lightning-induced surges. Thermal design leverages RθJA = 50 °C/W and RθJC = 15 °C/W to sustain 6.5 W steady-state dissipation on standard FR-4 PCBs with 1-in² copper pour.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V - defines guaranteed avalanche conduction onset across production lot; ±5% tolerance supports reliable margining above 12 V nominal rail |
| VWM | 11.1 V - maximum continuous DC or RMS voltage the device blocks without significant leakage; sets upper limit for protected circuit operating voltage |
| VC @ IPPM | 18.2 V @ 86 A - clamped voltage during 10/1000 µs surge; ensures downstream ICs rated for 20 V abs max remain within safe operating area |
| IR @ VWM | <1 µA - negligible standby power loss and no measurable loading on high-impedance sensor or reference circuits |
| PPK | 1500 W - peak surge energy absorption capacity per single event; meets Level 4 IEC 61000-4-5 (4 kV line-to-ground) |
| TJ Range | −55 °C to +150 °C - enables deployment in under-hood automotive ECUs and outdoor industrial gateways without derating |
| Package | DO-214AB (SMC) - industry-standard surface-mount outline with 0.210 g mass, UL 94V-0 molding, and matte tin-plated leads compliant with J-STD-002 solderability |
Pinout & Package
DO-214AB (SMC) package: molded plastic case with two coplanar gull-wing leads; cathode band marking denotes polarity for unidirectional variants only - absent on 1.5SMC13CA due to bidirectional symmetry. Leads are matte tin-plated, JESD 201 Class 2 whisker-resistant, and compatible with reflow and wave soldering per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | No fixed anode/cathode designation; either terminal serves as input or return path - simplifies PCB layout for differential or floating lines |
| Case (plastic body) | Thermal and mechanical interface | Non-conductive; heat transfer occurs via leadframe to PCB copper; requires ≥1-in² 2-oz copper pour for full 1500 W rating |
Key Features
| Feature | Design Value |
|---|---|
| Fast response time | <1.0 ps - enables clamping before ESD or surge energy couples into sensitive analog front-ends or MCU GPIOs |
| ISO 7637-2 compliance | Pulse 1 (inductive load dump), 2a/2b (supply transients), 3a/3b (capacitive coupling) - validated for automotive 12 V battery-line protection |
| Moisture sensitivity | Level 1 per J-STD-020 - zero bake requirement prior to reflow; supports standard SMT assembly without dry-pack handling |
| RoHS & halogen-free | Compliant per RoHS Directive 2011/65/EU and IEC 61249-2-21 - meets environmental requirements for EU and China RoHS markets |
| Clamping ratio (VC/VBR) | 1.33 - low overvoltage margin ensures minimal stress on protected 15 V tolerant components during worst-case surge |
Applications
| Industrial PLC Analog Inputs | Automotive Body Control Module (BCM) LIN Bus |
|---|---|
Use Scenario: Protection of 0–10 V or 4–20 mA analog sensor inputs against field-induced surges and ESD during maintenance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA (Bourns) | Same DO-214AA (SMB) package; 13 V VBR range (12.4–13.7 V); 600 W PPK rating - 60% lower surge capacity than 1.5SMC13CA | Limited to lower-energy transients (e.g., IEC 61000-4-2 ESD only); unsuitable for ISO 7637-2 Pulse 1 or 3b | Select SMBJ13CA only when board space is constrained and surge threat level is limited to human-body-model ESD. |
| 1.5KE13CA (ON Semiconductor) | Through-hole DO-15 package; identical 12.4–13.7 V VBR and 1500 W rating; slower response (~1 ns vs. <1 ps) due to higher junction capacitance | Not suitable for high-speed data lines; requires through-hole assembly and larger PCB real estate | Choose 1.5KE13CA only for legacy through-hole designs or where reflow compatibility is not required. |
Compared with SMBJ13CA and 1.5KE13CA, the 1.5SMC13CA uniquely combines SMC surface-mount compatibility, 1500 W surge rating, sub-1 ps response, and bidirectional symmetry - making it optimal for new industrial and automotive PCBs requiring high-density, high-reliability transient protection without layout or process compromises.

FAQ
What is the clamping voltage of the 1.5SMC13CA under maximum rated surge current?
The 1.5SMC13CA exhibits a maximum clamping voltage (VC) of 18.2 V when subjected to its rated peak pulse current (IPPM) of 86 A, measured using the standardized 10/1000 µs double-exponential waveform. This value is guaranteed across temperature (−55 °C to +150 °C) and ensures protected circuits remain below 20 V absolute maximum ratings during surge events. The 1.5SMC13CA achieves this with a clamping ratio of 1.33 relative to its VBR midpoint, confirming tight voltage control.
Is the 1.5SMC13CA suitable for bidirectional signal line protection?
Yes, the 1.5SMC13CA is explicitly designed for bidirectional operation, as indicated by the "CA" suffix per TSC documentation. Its symmetrical avalanche characteristics ensure identical breakdown and clamping behavior in both polarities - eliminating the need for orientation-aware placement on AC-coupled or floating differential lines such as RS-485, CAN, or LIN buses. The 1.5SMC13CA does not feature a cathode band marking, confirming its bidirectional construction.
What is the maximum leakage current of the 1.5SMC13CA at its working stand-off voltage?
The 1.5SMC13CA guarantees a maximum blocking leakage current (IR) of less than 1 µA when biased at its working stand-off voltage (VWM) of 11.1 V, measured at 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor interfaces and avoids unnecessary power drain in battery-operated devices. The 1.5SMC13CA maintains this specification across its full operating temperature range, supporting reliable performance in extended-temperature applications.
Does the 1.5SMC13CA meet automotive surge immunity standards?
Yes, the 1.5SMC13CA is validated to meet ISO 7637-2 for automotive transient immunity, covering Pulse 1 (inductive load dump), Pulse 2a/2b (supply transients), and Pulse 3a/3b (capacitive coupling). Its 1500 W peak power rating and 18.2 V clamping voltage enable robust protection of 12 V system nodes - including body control modules and infotainment interfaces - without requiring additional series impedance. The 1.5SMC13CA's DO-214AB package also complies with JESD 201 Class 2 whisker resistance for automotive reliability.
What is the thermal resistance profile of the 1.5SMC13CA, and how does it impact PCB layout?
The 1.5SMC13CA has a junction-to-case thermal resistance (RθJC) of 15 °C/W and a junction-to-ambient resistance (RθJA) of 50 °C/W on standard FR-4 with 1-in² 2-oz copper. To sustain its full 1500 W surge rating, the PCB must provide adequate copper area for heat spreading - typically ≥1-in² thermal pad connected to both top and bottom ground planes via ≥4 thermal vias. Without this, the 1.5SMC13CA's clamping performance may degrade under repetitive surge conditions due to junction temperature rise.
