Product details
Overview
1.5SMC160CAH from Taiwan Semiconductor is a bidirectional 1500W surface-mount transient voltage suppressor (TVS) diode with a 160V working stand-off voltage (VWM), 171V minimum breakdown voltage (VBR), and 219V maximum clamping voltage (VC) at 7.1A peak pulse current. It features AEC-Q101 qualification, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, and DO-214AB (SMC) packaging for automotive and industrial surge protection.
For engineers reviewing the 1.5SMC160CAH datasheet, 1.5SMC160CAH pinout, 1.5SMC160CAH application, or 1.5SMC160CAH equivalent, this device serves as a high-power, fast-response (sub-1ps) bidirectional TVS for ESD and load-switching transient suppression in DC power rails, CAN/LIN bus interfaces, and automotive control modules where clamping performance and reliability under harsh electrical environments are critical.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, delivering consistent clamping behavior without polarity dependency. Its glass-passivated junction ensures stable VBR temperature coefficient (0.108%/°C) and low leakage (<1μA at 136V), while the DO-214AB package enables automated placement and meets JESD201 Class 2 whisker resistance.
Thermal performance is defined by RθJA = 50°C/W and RθJC = 15°C/W, supporting operation from –55°C to +150°C junction temperature. The device sustains 1500W peak pulse power (10/1000μs waveform), with derating above 25°C ambient per Fig.2 and compliance to ANSI/IEEE C62.35 surge standards.
Key Specifications

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 | Lower PPK (600W), same VWM (136V), SMB package (smaller footprint, higher RθJA) | Suitable for lower-energy transients; not recommended for ISO 7637-2 Pulse 5a/b | Select when board space is constrained and surge energy does not exceed 600W |
| 1.5KE160CA | Higher PPK (1500W), axial leaded DO-201AD package, slower thermal response | Requires through-hole assembly; unsuitable for high-density SMT designs | Choose only for legacy through-hole systems or prototyping with breadboard compatibility |
Compared with 1.5SMC160CAH, SMBJ160CA offers reduced surge capability in a smaller SMT package, while 1.5KE160CA delivers equivalent power rating but lacks surface-mount compatibility and automated placement support-making 1.5SMC160CAH optimal for modern automotive and industrial SMT production.

FAQ
What is the clamping voltage of the 1.5SMC160CAH under a 10/1000μs surge?
The 1.5SMC160CAH exhibits a maximum clamping voltage (VC) of 219 V when subjected to a 10/1000μs waveform at 7.1 A peak impulse current. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during standardized surge events. The 1.5SMC160CAH maintains this clamping performance across its full operating temperature range.
Is the 1.5SMC160CAH suitable for bidirectional signal line protection?
Yes-the "CAH" suffix explicitly denotes bidirectional functionality, meaning the 1.5SMC160CAH provides symmetrical clamping in both polarities. It is commonly deployed across differential buses like CAN, LIN, or RS-485, where polarity-agnostic surge suppression is required. Unlike unidirectional variants, the 1.5SMC160CAH has no cathode band and functions identically regardless of terminal orientation.
Does the 1.5SMC160CAH meet automotive qualification standards?
Yes-the 1.5SMC160CAH is AEC-Q101 qualified and certified to withstand ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b waveforms. These qualifications validate its suitability for use in automotive power distribution, body electronics, and infotainment systems where robustness against load dump, switching noise, and ESD is mandatory. The 1.5SMC160CAH also complies with J-STD-020 Level 1 moisture sensitivity.
What is the maximum steady-state power dissipation for the 1.5SMC160CAH?
The 1.5SMC160CAH has a steady-state power dissipation (PD) rating of 6.5 W at 25°C ambient temperature. This value reflects continuous DC or low-frequency power handling capability-not surge-related. Derating applies above 25°C per the published thermal curve (Fig.2), with RθJA = 50°C/W establishing the thermal boundary for PCB layout design.
How does the 1.5SMC160CAH compare to the unidirectional 1.5SMC160CH?
The 1.5SMC160CAH is the bidirectional version of the 1.5SMC160CH, sharing identical VWM (136 V), VBR (152–168 V), and VC (219 V) specifications-but with symmetrical conduction in both directions. The 1.5SMC160CH includes a cathode band and is intended for single-polarity DC rail protection. Layouts using the 1.5SMC160CAH eliminate polarity concerns and simplify routing on differential or AC-coupled lines.
