Product details
Overview
1.5SMC10CA from Taiwan Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, rated for 1500W peak pulse power, 10.5V minimum breakdown voltage (VBR), 8.55V working stand-off voltage (VWM), and 14.5V maximum clamping voltage (VC) at 10.8A peak impulse current - used to protect DC power rails and I/O lines in telecom and industrial control systems.
For engineers reviewing the 1.5SMC10CA datasheet, 1.5SMC10CA pinout, 1.5SMC10CA application, or 1.5SMC10CA equivalent, key selection criteria include bidirectional ESD/TVS protection capability, sub-1ps response time, <1µA leakage at VWM, ISO 7637-2 compliance, and DO-214AB thermal performance (RθJA = 50°C/W).
Technical Context
This bidirectional TVS diode operates symmetrically in both polarities, with clamping action triggered when transient voltage exceeds its 10.5–10.5V breakdown range (VBR min/max). It delivers 1500W peak pulse power handling per 10/1000µs waveform per IEC 61000-4-5 and meets ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive load-dump and inductive switching immunity.
Its glass-passivated junction ensures stable leakage (<1µA at 8.55V), fast response (<1.0ps), and robust reliability under repeated transients. The device is rated for -55°C to +150°C junction temperature and features halogen-free, RoHS-compliant molding compound meeting UL 94V-0.
Key Specifications

| VC @ IPPM | 14.5V at 10.8A - clamped voltage during 10/1000µs surge, limiting downstream IC stress |
| PPK | 1500W - peak transient power dissipation capability per single 1ms pulse |
| IPPM | 10.8A - maximum non-repetitive surge current the device safely clamps |
| TJ max | +150°C - maximum junction temperature enabling operation in high-ambient industrial environments |

FAQ
What is the breakdown voltage tolerance for 1.5SMC10CA?
The 1.5SMC10CA has a guaranteed breakdown voltage (VBR) range of 9.50V to 10.5V at 1mA test current, measured per ANSI/IEEE C62.35. This ±5% tolerance ensures predictable clamping onset across production lots and temperature extremes, critical for consistent protection in safety-critical 12V systems.
Is 1.5SMC10CA unidirectional or bidirectional?
The "CA" suffix in 1.5SMC10CA explicitly denotes a bidirectional configuration. Unlike "C"-suffixed parts, 1.5SMC10CA provides symmetrical clamping in both polarities with identical VBR, VC, and IPPM characteristics - essential for protecting AC-coupled lines or floating DC buses where polarity reversal may occur.
What is the maximum clamping voltage of 1.5SMC10CA under surge conditions?
The 1.5SMC10CA clamps to a maximum of 14.5V when subjected to its rated 10.8A peak impulse current (IPPM) under the standard 10/1000µs waveform. This value is measured per IEC 61000-4-5 and defines the upper voltage limit imposed on protected circuitry during worst-case transients.
Does 1.5SMC10CA meet automotive transient standards?
Yes, 1.5SMC10CA meets ISO 7637-2 Pulse 1 (inductive switch-off), Pulse 2a/2b (battery disconnect), and Pulse 3a/3b (capacitive coupling) requirements. Its 1500W rating and 14.5V clamping enable compliance with Level IV immunity testing in body electronics and infotainment subsystems.
What is the thermal resistance of 1.5SMC10CA, and how does it affect PCB layout?
The 1.5SMC10CA has a junction-to-ambient thermal resistance (RθJA) of 50°C/W under standard JEDEC test conditions. To maintain TJ ≤150°C during repetitive surges, PCB layout must provide ≥40mm² of 2oz copper connected to both terminals - verified via thermal simulation or IR imaging per JEDEC 51-14.
