Product details
Overview
1.5SMC13CAH from Taiwan Semiconductor is a bidirectional 1500W surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, with breakdown voltage 12.4–13.7V at 1mA test current, working stand-off voltage 11.1V, maximum clamping voltage 18.2V at 86A peak impulse current, and AEC-Q101 qualification for automotive-grade surge protection in power supply rails and I/O lines.
For engineers reviewing the 1.5SMC13CAH datasheet, 1.5SMC13CAH pinout, 1.5SMC13CAH application, or 1.5SMC13CAH equivalent, this page delivers verified electrical specs, thermal resistance (RθJA = 50°C/W), ISO 7637-2 pulse compliance, polarity marking, and bidirectional ESD/TVS design guidance for telecom, industrial, and automotive systems.
Technical Context
The 1.5SMC13CAH is a glass-passivated, bipolar junction TVS diode designed for unidirectional or bidirectional transient suppression without external polarity constraints. Its symmetrical VBR (12.4–13.7V) and matched clamping behavior in both directions enable robust protection of differential signal lines and AC-coupled interfaces.
It delivers sub-1ps response time, <1μA leakage at 11.1V, and meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity. Thermal performance is defined by RθJC = 15°C/W and RθJA = 50°C/W, supporting high-reliability mounting on FR-4 PCBs with recommended SMC pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 12.4V / 13.7V at 1mA - defines minimum and maximum guaranteed breakdown threshold under standardized test conditions |
| VWM | 11.1V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | 18.2V at 86A - clamping voltage during 10/1000μs surge, limiting downstream device stress |
| PPK | 1500W - peak pulse power handling capability per single 1ms transient event |
| IR @ VWM | <1μA - ultra-low leakage ensures minimal standby power loss and signal integrity in high-impedance circuits |
| TJ range | −55°C to +150°C - full operational junction temperature range supporting under-hood automotive use |
| Package | DO-214AB (SMC) - industry-standard surface-mount outline with 0.210g mass and UL 94V-0 molding compound |
Pinout & Package
DO-214AB (SMC) package: molded plastic case with matte tin-plated leads, cathode band absent (bidirectional symmetry); polarity is non-applicable - terminals are functionally identical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional transient conduction path | Either terminal serves as anode or cathode depending on instantaneous polarity of surge - no orientation required during placement |
| Case (body) | Thermal and mechanical interface | Provides primary heat path to PCB copper; requires adequate thermal pad area per suggested layout for RθJA derating |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress-test requirements including temperature cycling, HTRB, and ESD |
| ISO 7637-2 compliant | Withstands Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (line impedance coupling) |
| Glass passivated junction | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift |
| Fast response <1ps | Clamps transients before sensitive ICs experience overstress - critical for protecting high-speed data lines and microcontrollers |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive for environmentally constrained applications |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12V battery-fed ECUs against load dump and alternator transients per ISO 7637-2. IC Role / Device Role / Timing Role: Bidirectional TVS placed across VIN and GND to clamp surges before LDOs or MCUs. Use Value: Limits peak rail voltage to ≤18.2V during 86A transients, preventing latch-up or permanent damage to 20V-rated regulators. |
Use Scenario: Shielding 4–20mA analog sensor inputs from ESD and field-wiring induced spikes in factory automation. IC Role / Device Role / Timing Role: Placed differentially across signal pair or common-mode across signal-to-ground to absorb ±15kV contact ESD. Use Value: Sub-1ps response ensures clamping occurs before op-amp input stages saturate, preserving measurement accuracy and avoiding recovery delays. |
| Telecom Line Interface Protection | Consumer USB Port Surge Suppression |
Use Scenario: Safeguarding Ethernet PHYs and PoE injectors from lightning-induced surges on twisted-pair cabling. IC Role / Device Role / Timing Role: Used in pairs (line-to-line and line-to-ground) to provide symmetric common-mode and differential-mode suppression. Use Value: Matched bidirectional VBR (12.4–13.7V) enables balanced clamping without skew, maintaining signal integrity on 100Ω differential lines. |
Use Scenario: Adding secondary-level surge defense on USB VBUS and D+/D− lines beyond internal port controller protection. IC Role / Device Role / Timing Role: Mounted directly at connector entry point to shunt fast transients before reaching USB switch or Type-C controller. Use Value: 1500W peak power rating absorbs multiple 8kV/15kV ESD events while maintaining <1μA leakage to avoid false insertion detection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA | Same 13V nominal VBR, but 600W PPK rating and SMB package (smaller footprint, higher RθJA ≈ 65°C/W) | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 1 or sustained load-dump events | Select when board space is constrained and surge energy is limited to IEC 61000-4-2/5 levels only |
| 1.5KE13CA | Through-hole TO-204AA (DO-41) package, same 13V VBR and 1500W rating, but slower response (~1ns) and no AEC-Q101 qualification | Not suitable for automated SMT assembly or automotive under-hood environments requiring vibration/thermal cycling validation | Choose only for legacy through-hole designs where rework flexibility outweighs AEC-Q101 and SMT compatibility needs |
Compared with SMBJ13CA and 1.5KE13CA, the 1.5SMC13CAH uniquely combines AEC-Q101 qualification, 1500W SMT-rated surge capacity, and sub-1ps response in DO-214AB - making it the preferred choice for new automotive and industrial designs requiring validated reliability and high-energy transient immunity.

FAQ
What is the exact breakdown voltage range for 1.5SMC13CAH?
The 1.5SMC13CAH has a guaranteed breakdown voltage range of 12.4V to 13.7V measured at 1mA test current (VBR @ IT = 1mA), per the manufacturer's electrical specifications table. This range reflects process variation and ensures consistent clamping behavior across production lots while maintaining compatibility with 12V system rails.
Is 1.5SMC13CAH unidirectional or bidirectional?
The 1.5SMC13CAH is a bidirectional TVS diode, indicated by the "CAH" suffix. It provides symmetrical clamping in both polarities - no cathode band marking is present, and either terminal may serve as anode or cathode depending on transient polarity. This enables simplified layout for AC-coupled or differential signal protection.
Does 1.5SMC13CAH meet automotive qualification standards?
Yes, the 1.5SMC13CAH is AEC-Q101 qualified and explicitly tested to ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b transient waveforms. Its −55°C to +150°C operating junction temperature range and JESD201 Class 2 whisker resistance further validate its suitability for under-hood and chassis-mounted automotive applications.
What is the maximum clamping voltage of 1.5SMC13CAH during a surge event?
The 1.5SMC13CAH clamps to a maximum of 18.2V when subjected to its rated 86A peak impulse current (IPPM) under the standard 10/1000μs waveform. This value is measured at TA = 25°C and defines the upper voltage limit imposed on protected circuitry during worst-case transient conditions.
What package type does 1.5SMC13CAH use, and what are its key mechanical features?
The 1.5SMC13CAH uses the DO-214AB (SMC) surface-mount package: a rectangular molded body with matte tin-plated leads, UL 94V-0 flammability rating, and 0.210g typical weight. Its polarity-neutral construction supports automated pick-and-place, and the recommended pad layout ensures optimal thermal dissipation with RθJA = 50°C/W.
