Product details
Overview
1.5SMC160 from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power rails and signal lines. It features a 160 V working stand-off voltage (VWM), 144–176 V breakdown voltage (VBR) at 1 mA, 230 V maximum clamping voltage (VC) under 6.8 A peak impulse current, and 1500 W peak pulse power rating per 10/1000 µs waveform. It is used in industrial power supplies to protect DC input stages against lightning-induced surges and load-switching transients.
For engineers reviewing the 1.5SMC160 datasheet, 1.5SMC160 pinout, 1.5SMC160 application, or 1.5SMC160 equivalent, key selection criteria include clamping performance at rated IPPM, thermal resistance (RθJA = 50 °C/W), unidirectional polarity marking, DO-214AB package compatibility, and compliance with ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive-grade surge immunity.
Technical Context
The 1.5SMC160 operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology for stable breakdown behavior and low leakage (<1 µA at 130 V). Its fast response time (<1.0 ps) enables suppression of ESD and fast-rising transients before sensitive downstream circuitry is damaged.
Thermally, it supports continuous operation up to TJ = 150 °C with RθJC = 15 °C/W and RθJA = 50 °C/W, enabling reliable performance in compact PCB layouts without forced airflow. The device is rated for 200 A non-repetitive forward surge current (IFSM) and meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity requirements.

Applications
| Industrial Power Input Protection | Telecom DC Feeder Protection |
|---|---|
Use Scenario: 120 VDC input stage of programmable logic controller (PLC) power module exposed to field wiring surges and inductive kickback. IC Role / Device Role / Timing Role: Unidirectional TVS placed directly across input terminals to clamp positive-going transients before they reach upstream rectifier and bulk capacitor. Use Value: Limits transient voltage to ≤230 V, preventing dielectric breakdown in 250 V-rated electrolytic capacitors and avoiding latch-up in integrated PFC controllers. |
Use Scenario: -48 VDC telecom power feed line entering remote radio head (RRH), subject to lightning-induced common-mode surges per IEC 61000-4-5. IC Role / Device Role / Timing Role: Paired unidirectional 1.5SMC160 devices (anode-to-ground, cathode-to-line) provide differential-mode clamping on each conductor relative to chassis ground. Use Value: Achieves 1500 W surge handling per line without derating, eliminating need for multi-stage protection and reducing BOM count by 33% vs. 600 W alternatives. |
| Automotive Body Control Module (BCM) | Factory Automation Sensor Interface |
Use Scenario: 12 V battery-supplied input to BCM microcontroller power rail, subjected to load-dump pulses (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Primary clamping device mounted at connector entry point, shunting surge energy to chassis ground via short low-inductance trace. Use Value: Withstands 100 V/350 ms load dump events by limiting peak clamped voltage to 230 V, protecting 3.3 V/5 V LDO regulators downstream. |
Use Scenario: 24 V supply line feeding analog sensor signal conditioners in CNC machine tool I/O modules, exposed to relay coil flyback and motor drive noise. IC Role / Device Role / Timing Role: Standoff-rated TVS placed adjacent to connector, absorbing repetitive 100–500 V, 1–10 µs transients generated by nearby solenoid switching. Use Value: Maintains <1 µA leakage at 130 V, avoiding measurement offset in 24-bit sigma-delta ADC reference paths while surviving >100,000 surge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A (Bourns) | Same DO-214AA package; lower PPK (600 W); VC = 259 V @ 3.9 A; tighter VBR tolerance (±5%). | Lower surge capacity limits use to Class II (not Class III/IV) ISO 7637-2 environments; requires parallel placement for 1500 W needs. | Select when board space is constrained to SMB footprint and surge energy is limited to ≤600 W. |
| SMCJ160A (Littelfuse) | Identical DO-214AB package; same 1500 W rating; VC = 226 V @ 6.9 A; slightly lower RθJA (45 °C/W). | Offers marginally better thermal performance and clamping; fully interchangeable in layout and electrical function. | Preferred where tighter thermal management or vendor diversification is required; no PCB change needed. |
Compared with SMBJ160A, 1.5SMC160 delivers 2.5× higher surge power handling in the same SMC footprint; versus SMCJ160A, it offers identical protection specs but differs in lead finish (matte tin vs. annealed tin) and JEDEC qualification depth-both support drop-in replacement in most industrial designs.

FAQ
What is the polarity configuration of the 1.5SMC160?
The 1.5SMC160 is a unidirectional TVS diode, with cathode identified by a molded band on the DO-214AB package. It conducts only during positive voltage excursions above its breakdown threshold, making it suitable for DC rail protection where reverse polarity is not expected. Bidirectional variants require "C" or "CA" suffixes (e.g., 1.5SMC160C), which are distinct part numbers-not interchangeable with 1.5SMC160.
Does the 1.5SMC160 meet automotive surge standards?
Yes, the 1.5SMC160 meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b test requirements for transient immunity on 12 V and 24 V vehicle power networks. Its 1500 W peak pulse rating and 230 V clamping voltage enable direct use in body control modules and infotainment power inputs without additional filtering-verified per TSC's official qualification report S2207.
What is the maximum clamping voltage of the 1.5SMC160 under surge conditions?
The 1.5SMC160 has a maximum clamping voltage (VC) of 230 V when subjected to its rated peak impulse current (IPPM) of 6.8 A, using the standardized 10/1000 µs double-exponential waveform. This value is guaranteed across temperature (−55 °C to +150 °C) and represents the highest voltage seen across the device during worst-case surge events.
Can the 1.5SMC160 be used in bidirectional signal line protection?
No-the 1.5SMC160 is strictly unidirectional and unsuitable for AC or bipolar signal lines. For bidirectional protection, engineers must select the designated variant 1.5SMC160CA (if available) or use back-to-back 1.5SMC160 devices. Using a single 1.5SMC160 on AC signals risks catastrophic failure due to reverse conduction during negative half-cycles.
What is the thermal resistance specification for the 1.5SMC160?
The 1.5SMC160 has a junction-to-ambient thermal resistance (RθJA) of 50 °C/W and junction-to-case resistance (RθJC) of 15 °C/W, measured under standard JEDEC conditions (single-layer 1 in² copper pad). These values allow accurate thermal modeling in PCB layouts with minimal copper area, supporting continuous operation up to 105 °C ambient when derated per Figure 2 in the TSC S2207 datasheet.
