Product details
Overview
1.5SMC160CA from Taiwan Semiconductor is a bidirectional 1500W surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, with 160V breakdown voltage (min 144V, max 176V), 130V working stand-off voltage, and 230V maximum clamping voltage at 6.8A peak impulse current. It protects power rails and signal lines in telecom and industrial equipment against ESD and lightning-induced transients.
For engineers reviewing the 1.5SMC160CA datasheet, 1.5SMC160CA pinout, 1.5SMC160CA application, or 1.5SMC160CA equivalent, key selection criteria include clamping voltage margin relative to system rail, unidirectional vs. bidirectional polarity requirements, thermal derating above 25°C, and compliance with ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive-grade surge immunity.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1µA at 130V), while sub-1ps response time guarantees suppression before sensitive downstream circuitry is stressed.
The device is rated for 1500W peak pulse power (10/1000µs waveform), with thermal resistance of 50°C/W junction-to-ambient and 15°C/W junction-to-case. It supports operating junction temperatures from –55°C to +150°C and meets J-STD-020 moisture sensitivity level 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 144V / 176V - defines guaranteed conduction onset range under 1mA test current; sets minimum overvoltage threshold before clamping begins |
| VWM | 130V - maximum continuous reverse working voltage; must exceed system nominal rail to avoid leakage-induced power loss |
| VC @ IPPM | 230V @ 6.8A - clamped voltage during 10/1000µs surge; determines worst-case stress on protected ICs |
| PPK | 1500W - peak pulse power rating per 10/1000µs waveform; defines single-event surge energy handling capability |
| IR @ VWM | <1µA - blocking leakage at rated stand-off voltage; critical for low-power or battery-operated circuits |
| TJ max | +150°C - maximum junction temperature; constrains PCB copper area and airflow requirements for sustained surge duty |
| Package | DO-214AB (SMC) - industry-standard surface-mount outline with 7.1mm × 6.2mm footprint and 2.6mm height; compatible with automated pick-and-place |
Pinout & Package
DO-214AB (SMC) package: molded plastic case with matte tin-plated leads, UL 94V-0 flammability rating, and polarity indicated by cathode band (bidirectional operation eliminates functional polarity dependence).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode | Bidirectional terminal pair | Identical electrical behavior in either direction; connected across protected line and ground (or between differential lines) without orientation constraint |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA (Bourns) | Same 160V VBR range, but 600W PPK rating and SMB package (smaller footprint, higher thermal resistance) | Lower surge energy handling; suitable only for lighter-duty consumer applications, not automotive or industrial | Select 1.5SMC160CA when 1500W single-pulse robustness or DO-214AB mechanical compatibility is required. |
| SMCJ160CA (Littelfuse) | Identical 1500W rating, DO-214AB package, and 160V VBR; differs in leakage spec (≤5µA vs. ≤1µA) and thermal resistance (RθJA = 55°C/W) | Higher leakage may affect ultra-low-power systems; slightly reduced thermal margin in high-ambient environments | Choose 1.5SMC160CA for tighter leakage control and better thermal performance in thermally constrained designs. |
Compared with SMBJ160CA and SMCJ160CA, the 1.5SMC160CA delivers superior leakage performance (<1µA), lower junction-to-ambient thermal resistance (50°C/W), and full ISO 7637-2 compliance - making it optimal for automotive and industrial applications demanding high reliability and repeatable surge immunity.

FAQ
What is the clamping voltage of the 1.5SMC160CA under a standard 10/1000µs surge?
The 1.5SMC160CA has a maximum clamping voltage (VC) of 230V when subjected to its rated peak impulse current of 6.8A under the 10/1000µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during a full-rated surge event. The 1.5SMC160CA maintains this clamping performance across its specified operating temperature range.
Is the 1.5SMC160CA unidirectional or bidirectional, and how does that affect PCB layout?
1.5SMC160CA is a bidirectional TVS diode, indicated by the "CA" suffix, meaning it provides symmetrical clamping in both polarities. Unlike unidirectional variants, it has no cathode marking requirement and can be mounted without orientation concern - simplifying PCB layout and eliminating risk of reverse installation. This makes the 1.5SMC160CA ideal for AC-coupled lines, differential buses, or floating grounds where polarity is undefined.
Does the 1.5SMC160CA meet automotive surge immunity standards?
Yes, the 1.5SMC160CA meets ISO 7637-2 requirements for Pulse 1 (inductive load dump), Pulse 2a/2b (battery interruption/switching), and Pulse 3a/3b (capacitive coupling), making it suitable for automotive body electronics and infotainment systems. Its 1500W peak power rating and 130V working stand-off voltage align directly with 12V system load-dump protection needs. The 1.5SMC160CA is not rated for ISO 7637-2 Pulse 5a (load dump), which requires higher VWM margin.
What is the maximum leakage current of the 1.5SMC160CA at its working stand-off voltage?
The 1.5SMC160CA exhibits a maximum blocking leakage current (IR) of 1µA when biased at its rated working stand-off voltage of 130V. This ultra-low leakage is confirmed per the manufacturer's electrical specifications table and is critical for preserving battery life in always-on systems and avoiding false triggering in high-impedance sensing circuits. The 1.5SMC160CA achieves this performance via glass-passivated junction technology.
Can the 1.5SMC160CA be used in place of a unidirectional 1.5SMC160A?
No - the 1.5SMC160CA and 1.5SMC160A are functionally distinct: the "CA" version is bidirectional, while the "A" version is unidirectional. Substituting 1.5SMC160CA for 1.5SMC160A would eliminate polarity-sensitive clamping behavior and may compromise protection on DC-biased lines. Always verify circuit topology: use 1.5SMC160CA for AC, differential, or floating nodes; use 1.5SMC160A for DC rails with defined ground reference. The 1.5SMC160CA cannot serve as a drop-in replacement for 1.5SMC160A without schematic and layout review.
