Product details
Overview
1.5SMC200C from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 200V breakdown voltage (VBR = 180–220 V), 1500W peak pulse power rating (tp = 1 ms), clamping voltage of 287 V at 5.4 A, and DO-214AB (SMC) package - used in telecom power input stages to protect downstream DC-DC converters from lightning-induced surges.
For engineers reviewing the 1.5SMC200C datasheet, 1.5SMC200C pinout, 1.5SMC200C application, or 1.5SMC200C equivalent, key selection criteria include working stand-off voltage (162 V), maximum clamping voltage under rated surge current, junction-to-ambient thermal resistance (50 °C/W), compliance with ISO 7637-2 Pulse 1/2a/2b/3a/3b, and moisture sensitivity level (J-STD-020 Level 1).
Technical Context
The 1.5SMC200C operates as a unidirectional avalanche diode, leveraging glass-passivated silicon junction technology to achieve sub-nanosecond response time (<1.0 ps) and low leakage (<1 µA at 162 V). Its clamping behavior follows standardized 10/1000 µs waveform per R.E.A., with peak impulse current (IPPM) defined at 5.4 A and corresponding VC = 287 V.
Thermally, it supports continuous operation up to TJ = 150 °C, with RθJA = 50 °C/W and RθJC = 15 °C/W. The device meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements, and is RoHS-compliant and halogen-free per IEC 61249-2-21.
Key Specifications

Use Value: Withstands 1500 W peak power and operates up to +150 °C junction temperature, enabling placement near hot engine-bay electronics. |
Use Scenario: Digital input channels (24 V sinking/sourcing) in PLC I/O modules connected to field sensors and actuators. IC Role / Device Role / Timing Role: Polarity-specific protection on each channel's supply rail to prevent latch-up or gate oxide rupture in interface logic. Use Value: Low leakage (<1 µA) avoids false triggering in high-impedance sensing circuits; DO-214AB footprint supports automated SMT assembly at scale. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | 600 W PPK, DO-214AA (SMB) package, VC = 324 V @ 3.1 A | Lower power rating; suitable only for lighter-duty 24 V systems, not 48 V telecom feeder lines | Select when board space is constrained and surge threat level is limited to IEC 61000-4-4 EFT only |
| 1.5KE200A | Through-hole DO-15 package, same VBR/VC specs but slower thermal recovery and no J-STD-020 Level 1 rating | Not suitable for high-volume SMT production; requires wave soldering or hand assembly | Select only for legacy through-hole designs or prototyping where reflow compatibility is not required |

FAQ
What is the polarity configuration of the 1.5SMC200C?
The 1.5SMC200C is a unidirectional TVS diode, configured with anode and cathode terminals. The cathode is marked by a molded band on the DO-214AB (SMC) package body. It conducts surge current from anode to cathode during positive transients on the anode side relative to cathode, and blocks reverse voltage up to its specified VWM of 162 V. This polarity must be observed during PCB layout to ensure correct clamping direction in the 1.5SMC200C application.
Does the 1.5SMC200C meet automotive surge standards?
Yes, the 1.5SMC200C meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b requirements for transient immunity on vehicle power networks. Its 1500 W peak pulse power rating and 287 V clamping voltage at 5.4 A enable effective suppression of coupled transients from alternator load dump, relay switching, and inductive kickback - making it suitable for use in automotive body control modules and infotainment power supplies where the 1.5SMC200C is deployed.
What is the maximum operating temperature for the 1.5SMC200C?
The 1.5SMC200C has a maximum junction temperature (TJ) of +150 °C and a storage temperature range of –55 °C to +150 °C. Its thermal resistance values - RθJA = 50 °C/W and RθJC = 15 °C/W - allow reliable operation in thermally demanding environments such as enclosed industrial enclosures or under-hood automotive locations, provided PCB copper area and airflow align with the 1.5SMC200C thermal design guidelines.
How does the 1.5SMC200C differ from the 1.5SMC200CA variant?
The 1.5SMC200C is unidirectional, while the 1.5SMC200CA is bidirectional - meaning the latter clamps transients of either polarity and has no cathode marking. The 1.5SMC200C exhibits lower leakage (<1 µA at 162 V) and is optimized for DC rail protection where polarity is fixed; the CA version sacrifices some leakage performance for symmetrical clamping, making it appropriate for AC-coupled signal lines. Both share identical VBR, VC, and PPK ratings, but the 1.5SMC200C must be oriented correctly during placement.
Is the 1.5SMC200C compatible with lead-free reflow processes?
Yes, the 1.5SMC200C uses matte tin-plated leads compliant with J-STD-002 for solderability and is rated for lead-free reflow per J-STD-020 Level 1 - meaning it has unlimited floor life and withstands peak reflow temperatures up to 260 °C without preconditioning or baking. Its DO-214AB (SMC) package is fully compatible with standard SMT assembly lines handling the 1.5SMC200C, supporting high-yield, automated manufacturing.
