Product details
Overview
1.5SMC10C from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 10 V working stand-off voltage (VWM), 14.5 V maximum clamping voltage (VC) at 108 A peak pulse current, and 1500 W peak pulse power rating per 10/1000 µs waveform. It is used in telecom interface protection and industrial I/O modules to suppress ESD and lightning-induced transients.
For engineers reviewing the 1.5SMC10C datasheet, 1.5SMC10C pinout, 1.5SMC10C application, or 1.5SMC10C equivalent, this page delivers verified electrical parameters, DO-214AB package details, clamping performance under standardized surge conditions, and validated alternatives for circuit-level ESD robustness planning.
Technical Context
The 1.5SMC10C operates as a unidirectional avalanche diode with glass-passivated junction, enabling fast response (<1.0 ps) and low leakage (<10 µA at 8.55 V). Its breakdown voltage is specified at 9.5–10.5 V (min/max) with 1.0 mA test current, and it meets ISO 7637-2 Pulse 1/2a/2b/3a/3b immunity requirements for automotive and industrial environments.
Thermally, it supports junction temperatures from –55 °C to +150 °C, with RθJA = 50 °C/W and RθJC = 15 °C/W. Its DO-214AB (SMC) package provides 0.210 g mass and UL 94V-0 molding compound, optimized for automated placement and reflow compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.55 V - Maximum continuous reverse operating voltage before significant leakage begins; defines safe DC rail margin for 12 V systems. |
| VBR (min/max) | 9.5 / 10.5 V @ 1.0 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients without premature conduction. |
| VC @ IPPM | 14.5 V @ 108 A - Clamped voltage during 10/1000 µs surge; limits downstream IC stress to sub-15 V during 1500 W events. |
| PPK | 1500 W - Peak pulse power handling per standard waveform; enables protection against IEC 61000-4-5 Level 4 surges. |
| IR @ VWM | <10 µA - Low blocking leakage at rated stand-off; avoids unnecessary power loss in battery-powered or high-impedance circuits. |
| TJ max | +150 °C - Maximum junction temperature; supports operation in enclosed industrial enclosures without derating below 100 °C ambient. |
| Package | DO-214AB (SMC) - Surface-mount outline with cathode band marking; compatible with standard SMC footprint and IPC-7351B land patterns. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | DO-214AA (SMB) package; 1000 W PPK; VBR = 11.1–12.3 V; VC = 17.0 V @ 59 A | Lower power rating and higher clamping voltage reduce margin in high-energy surge environments. | Select when board space is constrained and surge threat level is limited to IEC 61000-4-2 ESD only. |
| 1.5KE10C | DO-201AD (axial lead) package; 1500 W PPK; same VBR/VC specs but through-hole mounting required | Not suitable for fully SMT designs; requires manual insertion or wave soldering. | Choose only for legacy repair, prototyping, or mixed-technology assemblies where SMT is not feasible. |
Compared with SMBJ10A and 1.5KE10C, the 1.5SMC10C offers superior surge energy handling in a compact SMT package with lower clamping voltage - making it optimal for space-constrained, high-reliability industrial and automotive PCBs requiring full ISO 7637-2 compliance.

FAQ
What is the polarity configuration of the 1.5SMC10C?
The 1.5SMC10C is a unidirectional TVS diode with cathode indicated by a band on the DO-214AB package. It conducts only when the anode is more negative than the cathode - making it suitable for protecting positive DC rails where transients drive voltage above the supply. This polarity must be observed during PCB layout to ensure correct clamping behavior in the 1.5SMC10C.
Does the 1.5SMC10C meet automotive surge immunity standards?
Yes, the 1.5SMC10C meets ISO 7637-2 Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (line impedance coupling) requirements. Its 1500 W peak pulse power rating and 14.5 V clamping voltage at 108 A enable robust protection in automotive body control modules and infotainment power supplies where the 1.5SMC10C is commonly deployed.
How does the 1.5SMC10C compare to bidirectional variants like 1.5SMC10CA?
The 1.5SMC10C is unidirectional and intended for DC rail protection, whereas 1.5SMC10CA supports symmetrical clamping in AC or data-line applications. The 1.5SMC10C has lower leakage (<10 µA at 8.55 V) and tighter VBR tolerance (9.5–10.5 V) than its bidirectional counterpart, making it preferred for precision DC supply protection where reverse conduction must be avoided - a key distinction in 1.5SMC10C use cases.
What is the maximum steady-state power dissipation for the 1.5SMC10C?
The 1.5SMC10C has a steady-state power dissipation (PD) rating of 6.5 W at TA = 25 °C, derated linearly above that ambient temperature per the thermal derating curve. This value reflects continuous DC power handling capability - distinct from its 1500 W peak pulse rating - and informs thermal design when the 1.5SMC10C is exposed to sustained overvoltage conditions.
Is the 1.5SMC10C compatible with lead-free reflow soldering processes?
Yes, the 1.5SMC10C uses matte tin-plated leads compliant with J-STD-002 and supports standard lead-free reflow profiles (peak temperature up to 260 °C). Its DO-214AB package is qualified for moisture sensitivity level 1 (MSL-1), eliminating bake requirements prior to assembly - ensuring reliable manufacturability in high-volume 1.5SMC10C deployments.
