Product details
Overview
1.5SMC200CA from Taiwan Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and signal interfaces. It delivers 1500W peak pulse power at 10/1000μs, clamps transients to ≤274V at 5.7A, and features a 171V working stand-off voltage with <1μA leakage above 171V - deployed in telecom line cards and industrial I/O modules.
For engineers reviewing the 1.5SMC200CA datasheet, 1.5SMC200CA pinout, 1.5SMC200CA application, or 1.5SMC200CA equivalent, key selection criteria include bidirectional clamping capability, DO-214AB package thermal performance (RθJC = 15°C/W), compliance with ISO 7637-2 Pulse 1/2a/2b/3a/3b, and verified ESD immunity up to ±30kV contact per IEC 61000-4-2.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1MΩ) up to 171V; during transients exceeding breakdown (190–210V @ 1mA), it avalanches rapidly (<1ps response) to divert surge current away from downstream circuitry. Its bidirectional symmetry ensures identical clamping in both polarities, eliminating polarity-sensitive layout constraints.
Thermally, the device sustains 150°C junction temperature with 50°C/W junction-to-ambient resistance in standard PCB mounting. The glass-passivated junction and matte tin-plated leads meet J-STD-002 solderability and JESD 201 Class 2 whisker resistance requirements - critical for automotive and industrial reflow assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000μs) | 1500W - sustains single-event surges up to 5.7A without failure |
| Working Stand-off Voltage (VWM) | 171V - maximum continuous DC or RMS voltage before leakage exceeds 1μA |
| Breakdown Voltage (VBR) | 190–210V @ 1mA - precise avalanche threshold enabling predictable clamping onset |
| Maximum Clamping Voltage (VC) | 274V @ 5.7A - limits protected circuit voltage during worst-case surge |
| Junction Temperature Range | −55°C to +150°C - supports operation in under-hood automotive and industrial ambient environments |
| Package | DO-214AB (SMC) - surface-mount footprint compatible with automated placement and IPC-7351B land patterns |
| Leakage Current (IR) | <1μA @ 171V - negligible standby power loss in always-on systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA (Bourns) | Same DO-214AA package; lower PPPK = 600W; VC = 324V @ 1.9A | Limited to sub-2kW surge environments; unsuitable for ISO 7637-2 Pulse 5a | Select only when board space restricts SMC footprint and surge energy is ≤600W |
| SMCJ200CA (Littelfuse) | Identical DO-214AB package; PPPK = 1500W; VC = 276V @ 5.5A; RθJA = 55°C/W | Marginally higher clamping voltage and worse thermal resistance than 1.5SMC200CA | Acceptable where 2V clamping margin is available and thermal derating allows 5°C/W penalty |
Compared with SMBJ200CA and SMCJ200CA, the 1.5SMC200CA offers superior thermal performance (RθJC = 15°C/W vs. ≥20°C/W), tighter VBR tolerance (±5% vs. ±10%), and proven ISO 7637-2 Pulse 5a resilience - making it preferred for automotive and industrial 24V/48V rail protection where reliability margins are constrained.

FAQ
What is the clamping voltage of the 1.5SMC200CA at its rated peak pulse current?
The 1.5SMC200CA has a maximum clamping voltage (VC) of 274V when subjected to its rated peak impulse current (IPPM) of 5.7A under the standard 10/1000μs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream circuitry will not experience voltages exceeding 274V during defined surge events - a critical parameter for protecting 200V-rated capacitors and MOSFETs in DC link applications.
Is the 1.5SMC200CA unidirectional or bidirectional, and how is polarity indicated?
The 1.5SMC200CA is a bidirectional TVS diode, meaning it provides symmetrical clamping in both positive and negative voltage directions. Unlike unidirectional variants (e.g., 1.5SMC200A), it has no cathode band or polarity marking - both terminals are functionally identical. This eliminates orientation errors during automated placement and simplifies layout for AC-coupled or floating signal lines such as RS-485 or CAN bus stubs.
Does the 1.5SMC200CA meet automotive surge immunity standards?
Yes, the 1.5SMC200CA meets ISO 7637-2 requirements for Pulses 1, 2a, 2b, 3a, and 3b - covering key automotive transients including load dump, supply interruption, and capacitive coupling. While not AEC-Q200 certified out-of-box, its construction (glass passivation, MSL Level 1, −55°C to +150°C TJ) aligns with automotive qualification prerequisites, and it is widely deployed in body control modules and infotainment power rails.
What is the thermal resistance from junction to case (RθJC) for the 1.5SMC200CA?
The 1.5SMC200CA has a typical junction-to-case thermal resistance (RθJC) of 15°C/W, measured under standardized test conditions per JESD51-1. This low value enables efficient heat transfer to the PCB copper pour or heatsink, supporting sustained operation at elevated ambient temperatures - especially important in enclosed enclosures where junction temperature must remain below 150°C during repetitive surge events.
How does the 1.5SMC200CA compare to the 1.5SMC200A in terms of electrical performance?
The 1.5SMC200CA differs from the 1.5SMC200A primarily in polarity configuration: the "CA" suffix denotes bidirectional operation, while "A" indicates unidirectional. Electrically, both share identical VBR (190–210V), VWM (171V), and PPPK (1500W), but the 1.5SMC200CA exhibits matched clamping in both directions (VC = 274V ±0V polarity dependence), whereas the 1.5SMC200A clamps only in reverse bias and conducts forward like a rectifier diode.
