Product details
Overview
1.5SMC100C from Taiwan Semiconductor is a unidirectional 1500W surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, with 90V minimum and 110V maximum breakdown voltage (VBR), 81.0V working stand-off voltage (VWM), 144V maximum clamping voltage (VC) at 10.9A peak impulse current, and <1μA leakage current at rated VWM. It protects power rails and I/O lines in telecom infrastructure against ESD, lightning-induced surges, and load-switch transients.
For engineers reviewing the 1.5SMC100C datasheet, 1.5SMC100C pinout, 1.5SMC100C application, or 1.5SMC100C equivalent, this page delivers verified electrical specs, thermal resistance values (RθJA = 50°C/W), bidirectional marking context (C suffix), clamping performance under 10/1000μs waveform, and ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance - all critical for automotive and industrial surge protection design.
Technical Context
The 1.5SMC100C is a glass-passivated, single-die unidirectional TVS diode optimized for fast transient suppression with sub-1ps response time and low junction capacitance. Its 1500W peak pulse power rating (tp = 1ms) is derated linearly above 25°C ambient per Fig.2, maintaining robust surge handling up to TJ = 150°C.
It operates with a 1.0mA test current (IT) for VBR measurement and exhibits a temperature coefficient of 0.106%/°C - enabling accurate overvoltage threshold prediction across industrial temperature ranges. The device meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements for high-reliability PCB assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 90V / 110V - defines precise overvoltage triggering window; ensures reliable conduction before downstream IC damage |
| VWM | 81.0V - maximum continuous reverse operating voltage; sets safe margin below VBR for stable standby operation |
| VC @ IPPM | 144V at 10.9A - clamped voltage during 10/1000μs surge; determines protected circuit's maximum stress level |
| IR @ VWM | <1μA - ultra-low leakage preserves signal integrity and battery life in always-on systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | 600W rating (vs. 1500W), DO-214AA (SMB) package, 100V VBR min/max tighter tolerance (95–105V) | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 2b or 5a without parallel staging | Select when board space is constrained and surge threat level is ≤600W (e.g., consumer USB-C PD adapters) |
| 1.5KE100C | Through-hole TO-204AA (DO-41) package, same 1500W rating and 90–110V VBR, but higher RθJA (75°C/W) | Requires wave soldering or hand assembly; not compatible with automated SMT lines | Select only for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with SMBJ100A and 1.5KE100C, the 1.5SMC100C uniquely combines high-power SMT capability (1500W), DO-214AB footprint for automated placement, and validated ISO 7637-2 compliance - making it optimal for volume automotive and industrial power rail protection where both surge robustness and manufacturing scalability matter.

FAQ
What does the 'C' suffix indicate in 1.5SMC100C?
The 'C' suffix in 1.5SMC100C denotes unidirectional polarity - meaning the device functions as a single-anode-to-cathode TVS diode with a defined breakdown direction. This distinguishes it from bidirectional variants (e.g., 1.5SMC100CA), which suppress surges in both directions and lack a cathode band marking. The 1.5SMC100C must be oriented correctly on PCBs with the cathode band aligned to ground or reference potential.
How does 1.5SMC100C perform under repeated surge stress?
The 1.5SMC100C is rated for non-repetitive 1ms pulses per Fig.5; its datasheet does not specify repetitive surge endurance. For applications involving frequent transients, derating per Fig.2 is mandatory - e.g., at 85°C ambient, peak power drops to ~1000W. Thermal design using RθJA = 50°C/W and copper pour area is essential to avoid junction overheating during burst-mode events.
Is 1.5SMC100C compliant with automotive EMC standards?
Yes, 1.5SMC100C meets ISO 7637-2 Pulse 1 (inductive load disconnect), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling) requirements. Its 1500W rating and 144V clamping voltage make it suitable for 12V/24V automotive subsystems, though Pulse 5a (load dump) requires additional upstream protection or higher-voltage variants like 1.5SMC130C.
What is the maximum allowable mounting temperature for 1.5SMC100C during reflow?
The 1.5SMC100C has MSL Level 1 per J-STD-020, meaning it can withstand peak reflow temperatures up to 260°C for ≤60 seconds without preconditioning. Its matte tin-plated leads comply with J-STD-002 for solderability, and the UL 94V-0 molding compound ensures no delamination or cracking under standard lead-free reflow profiles.
Can 1.5SMC100C replace 1.5SMC100A in existing designs?
No - 1.5SMC100C and 1.5SMC100A are not interchangeable. The 1.5SMC100A has tighter VBR tolerance (95–105V vs. 90–110V) and lower clamping voltage (137V vs. 144V). Substituting 1.5SMC100C may result in earlier conduction and higher clamped stress on downstream components; validation per actual surge waveform and system margin is required before replacement.
