Product details
Overview
1.5SMC160C from Taiwan Semiconductor is a unidirectional 1500W surface-mount transient voltage suppressor (TVS) diode with a breakdown voltage of 144–176 V, clamping voltage of 230 V at 6.8 A peak pulse current, and DO-214AB (SMC) package. It protects power rails and signal lines in industrial power supplies and telecom interfaces against ESD, lightning surges, and load-switching transients.
For engineers reviewing the 1.5SMC160C datasheet, 1.5SMC160C pinout, 1.5SMC160C application, or 1.5SMC160C equivalent, this page delivers verified electrical specs, thermal performance data, bidirectional variant context, ISO 7637-2 compliance details, and real-world protection use cases - all specific to the 1.5SMC160C part number.
Technical Context
The 1.5SMC160C is a unidirectional TVS diode optimized for high-energy transient suppression in DC power circuits. Its glass-passivated junction ensures stable breakdown behavior, while its 1500 W peak pulse power rating (10/1000 µs waveform) and 230 V clamping voltage at 6.8 A support robust protection of 130–160 V nominal systems.
It operates across –55 °C to +150 °C junction temperature range, with 50 °C/W junction-to-ambient thermal resistance and 15 °C/W junction-to-case resistance. The device meets ISO 7637-2 Pulse 1/2a/2b/3a/3b standards and exhibits <1 µA leakage at 130 V working stand-off voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 144 V / 176 V - Ensures reliable turn-on above 130 V system rail while avoiding false triggering during normal operation |
| VWM | 130 V - Maximum continuous reverse operating voltage compatible with 130 V DC bus applications |
| VC @ IPPM | 230 V at 6.8 A - Clamped voltage limits downstream component stress during 10/1000 µs surge events |
| PPK | 1500 W - Sustains high-energy transients per ISO 7637-2 without degradation |
| IR @ VWM | <1 µA - Negligible leakage preserves efficiency in high-impedance monitoring or bias circuits |
| TJ max | +150 °C - Enables deployment in under-hood automotive modules or enclosed industrial enclosures |
| RθJA | 50 °C/W - Supports thermal design with standard PCB copper area (≥1 in²) without forced airflow |

Applications
| Industrial Power Supply Protection | Telecom DC Feeder Line Protection |
|---|---|
|
Use Scenario: 130 V DC input stage of programmable logic controller (PLC) power module exposed to field wiring surges. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between input rail and chassis ground to shunt surge energy away from upstream rectifier and downstream DC-DC controller. Use Value: Limits transient voltage to ≤230 V, preventing latch-up or gate oxide rupture in 200 V-rated MOSFETs and controllers on the same board. |
Use Scenario: -48 V telecom central office feeder line interface subject to lightning-induced common-mode surges up to 1 kV. IC Role / Device Role / Timing Role: Paired unidirectional 1.5SMC160C devices (anode-to-ground) protect positive and negative rails in redundant power feed architecture. Use Value: Withstands 1500 W pulses without degradation, maintaining system uptime during outdoor cabinet surges per ITU-T K.21 basic protection level. |
| Automotive Body Control Module (BCM) | Renewable Energy Inverter DC Link |
|
Use Scenario: 12 V auxiliary supply rail in BCM subjected to load-dump transients per ISO 7637-2 Pulse 5a (up to 60 V). IC Role / Device Role / Timing Role: Secondary clamping device downstream of primary TVS, handling residual overshoot after main suppression. Use Value: Provides margin beyond 130 V VWM, enabling safe operation even with ±10% battery voltage drift and aging-related leakage increase. |
Use Scenario: DC link capacitor protection in solar string inverters where PV array open-circuit voltage reaches 1500 V, but local DC bus operates at 130–160 V. IC Role / Device Role / Timing Role: Overvoltage clamp on auxiliary control supply derived from DC link via resistive divider or isolated DC-DC converter. Use Value: Prevents destructive overvoltage on 150 V-rated optocouplers and gate drivers during fast-rising partial discharge events in high-voltage capacitors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | Same VBR range (144–176 V), lower PPK = 600 W, SMB package (smaller footprint, higher RθJA = 65 °C/W) | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 1 or sustained 10/1000 µs surges above 600 W | Select when space-constrained layout prioritizes footprint over surge margin, and system-level testing confirms sub-600 W threat profile |
| 1.5KE160A | Same VBR/VC specs, axial-leaded DO-201 package, identical 1500 W rating, but no ISO 7637-2 validation or SMT process compatibility | Requires through-hole assembly; incompatible with automated pick-and-place; not rated for moisture-sensitive reflow profiles | Choose only for legacy through-hole designs or prototyping where reflow compatibility and JEDEC-compliant tape-and-reel delivery are not required |
Compared with SMBJ160A and 1.5KE160A, the 1.5SMC160C uniquely combines full 1500 W surge capability, DO-214AB SMT manufacturability, ISO 7637-2 certification, and moisture-level-1 reflow readiness - making it the preferred choice for volume production of industrial and automotive electronics requiring validated, high-reliability transient protection.

FAQ
What is the polarity configuration of the 1.5SMC160C?
The 1.5SMC160C is a unidirectional TVS diode, with cathode marked by a band on the DO-214AB package. It conducts only during reverse-biased overvoltage events - i.e., when the cathode voltage exceeds the anode by ≥144 V - and blocks normal forward current. This configuration is ideal for DC rail protection where polarity is fixed and reverse conduction must be prevented.
Does the 1.5SMC160C meet automotive transient immunity standards?
Yes, the 1.5SMC160C is explicitly validated to meet ISO 7637-2 Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (line spikes). Its 1500 W peak pulse power rating and 230 V clamping voltage enable compliance with Level III and IV requirements in 12 V and 24 V automotive subsystems, including body control modules and power distribution units.
How does the 1.5SMC160C differ from the 1.5SMC160CA variant?
The 1.5SMC160C is unidirectional, while the 1.5SMC160CA is bidirectional - meaning the CA version clamps symmetrically for both polarities and has no cathode marking. The 1.5SMC160C's VBR is specified only in reverse, whereas the CA variant's breakdown applies equally in both directions. Use 1.5SMC160C for DC rails with known polarity; choose 1.5SMC160CA only for AC-coupled or floating signal lines.
What is the maximum allowable PCB pad temperature during reflow for the 1.5SMC160C?
The 1.5SMC160C is rated for moisture sensitivity level 1 per J-STD-020, permitting unlimited floor life and standard lead-free reflow profiles. Peak reflow temperature may reach 260 °C for ≤10 seconds, with ramp rates ≤3 °C/s pre-peak and cooling rate ≤6 °C/s post-peak - fully compatible with IPC/JEDEC J-STD-020D.1 specifications.
Can the 1.5SMC160C be used in parallel to increase surge current handling?
No - the 1.5SMC160C should not be paralleled without external current-sharing resistors or matched dynamic impedance. Due to VBR tolerance (±5%), inherent parameter variation causes uneven current division during transients, risking thermal runaway in one device. For higher IPPM, select a single higher-rated TVS (e.g., 3.0SMC160C) or verify derated parallel operation with SPICE simulation and empirical testing.
