Product details
Overview
1.5SMC110CA from Taiwan Semiconductor is a bidirectional 1500W surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, with 110V breakdown voltage (min 99V, max 121V), 89.2V working stand-off voltage, and 152V clamping voltage at 10.3A peak pulse current. It protects telecom and industrial interfaces against ESD, lightning surges, and load-switch transients.
For engineers reviewing the 1.5SMC110CA datasheet, 1.5SMC110CA pinout, 1.5SMC110CA application, or 1.5SMC110CA equivalent, this page delivers verified electrical specs, thermal performance, ISO 7637-2 compliance, bidirectional clamping behavior, and real-world design implications for surge protection layout and reliability validation.
Technical Context
The 1.5SMC110CA uses a glass-passivated silicon junction optimized for fast response (<1.0 ps) and low leakage (<1 µA at 89.2V). Its bidirectional configuration enables symmetrical clamping in AC-coupled or floating signal lines without polarity constraints.
It operates across –55°C to +150°C junction temperature, with 15 °C/W junction-to-case and 50 °C/W junction-to-ambient thermal resistance. The device meets ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive transient immunity and complies with RoHS and IEC 61249-2-21 halogen-free standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 99 V / 121 V - Ensures reliable conduction onset above system operating voltage while avoiding false triggering |
| VWM | 89.2 V - Maximum continuous reverse voltage before leakage exceeds 1 µA; sets safe margin below VBR |
| VC @ IPPM | 152 V at 10.3 A - Clamped voltage during 10/1000 µs surge; defines worst-case stress on downstream ICs |
| PPK | 1500 W - Peak pulse power handling per single 10/1000 µs waveform; determines survivability of high-energy transients |
| IR @ VWM | <1 µA - Ultra-low leakage preserves signal integrity and battery life in always-on circuits |
| TJ max | +150 °C - Enables use in under-hood automotive or enclosed industrial enclosures without derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA (Bourns) | Same DO-214AA (SMB) package; 110 V VBR, 1000 W PPK, 177 V VC @ 5.6 A | Lower power rating limits use in high-energy automotive pulses; requires higher PCB trace width for same current density | Select when space-constrained layouts favor SMB footprint and surge energy is limited to ≤1000 W |
| SMCJ110CA (Littelfuse) | Identical DO-214AB (SMC) package; 110 V VBR, 1500 W PPK, 152 V VC @ 10.3 A - matches 1.5SMC110CA spec-for-spec | No functional or layout difference; validated for same ISO 7637-2 and IEC 61000-4-5 test profiles | Drop-in alternative with identical thermal and electrical performance; preferred where dual-sourcing is required |

FAQ
What is the clamping voltage of the 1.5SMC110CA under a 10/1000 µs surge?
The 1.5SMC110CA clamps to a maximum of 152 V at 10.3 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured per Fig.5 in the datasheet and defines the upper voltage limit imposed on protected circuitry during surge events, ensuring downstream components such as CAN transceivers or RS-485 drivers remain within their absolute maximum ratings.
Is the 1.5SMC110CA unidirectional or bidirectional?
The 1.5SMC110CA is a bidirectional TVS diode, indicated by the "CA" suffix per TSC documentation. It provides symmetrical clamping in both polarities, making it suitable for AC-coupled lines, differential interfaces (e.g., RS-485, CAN), or any application where voltage transients may occur with either polarity relative to ground.
Does the 1.5SMC110CA meet automotive transient immunity standards?
Yes, the 1.5SMC110CA meets ISO 7637-2 for automotive applications, specifically validated for Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling). Its 1500 W peak power rating and 152 V clamping voltage enable reliable protection in engine control units, body control modules, and infotainment systems.
What is the moisture sensitivity level (MSL) of the 1.5SMC110CA?
The 1.5SMC110CA has a moisture sensitivity level of MSL Level 1 per J-STD-020, meaning it can be stored indefinitely at ambient conditions and requires no baking prior to surface-mount reflow. This simplifies manufacturing logistics and eliminates yield loss from popcorning during assembly.
How does the 1.5SMC110CA compare to the 1.5SMC110A in terms of electrical performance?
The 1.5SMC110A is unidirectional, while the 1.5SMC110CA is bidirectional - the only structural difference. Their key parameters match exactly: VBR (99–121 V), VWM (89.2 V), VC (152 V @ 10.3 A), and PPK (1500 W). Choose 1.5SMC110CA for AC or floating signal lines; select 1.5SMC110A only when polarity is fixed and cathode grounding is required.
