Product details
Overview
SMCJ160CH from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, with 160V working stand-off voltage (VWM), 178–218V breakdown voltage (VBR), and 287V maximum clamping voltage (VC) at 5.4A peak impulse current. It delivers AEC-Q101 qualification, ISO 7637-2 pulse immunity, and sub-1ps response for automotive power line protection.
For engineers reviewing the SMCJ160CH datasheet, SMCJ160CH pinout, SMCJ160CH application, or SMCJ160CH equivalent, key selection criteria include clamping performance under 10/1000μs surge, unidirectional polarity marking, thermal resistance (RθJC = 10°C/W), and compliance with automotive ESD and load-dump transients.
Technical Context
The SMCJ160CH is a glass-passivated, single-die unidirectional TVS diode optimized for high-energy transient suppression on DC power rails. Its junction-to-case thermal resistance of 10°C/W enables reliable operation up to 150°C junction temperature, while its <1.0ps response time ensures clamping before sensitive downstream circuitry is stressed.
Designed for automotive-grade reliability, it meets AEC-Q101 stress testing and ISO 7637-2 Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (ESD-coupled noise). Reverse leakage remains ≤1μA at 160V, supporting low-power standby integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 178–218 V @ IT = 1 mA - Confirmed breakdown range ensuring predictable turn-on margin above VWM |
| VC @ IPPM | 287 V @ 5.4 A - Clamped voltage during 10/1000μs surge; limits downstream IC stress to safe levels |
| PPK | 1500 W - Peak pulse power handling per single 1ms transient, derated linearly above 25°C ambient |
| RθJC | 10 °C/W - Enables direct heatsinking to PCB copper; supports >3W steady-state dissipation with minimal ΔT |
| IR @ VWM | ≤1 μA - Negligible leakage at rated stand-off, critical for battery-backed or low-quiescent systems |
| TJ max | +150 °C - Rated junction temperature allowing use in under-hood automotive environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | Lower PPK (600W), SMB package (smaller footprint, higher RθJA = 85°C/W) | Suitable only for lower-energy transients; not recommended for ISO 7637-2 Pulse 2b compliance | Select SMCJ160CH where full 1500W surge rating and automotive qualification are mandatory |
| TPSMD160 | Same DO-214AB package, but 170V VWM and 290V VC; slightly higher clamping voltage | Acceptable for non-AEC-Q101 industrial designs; lacks ISO 7637-2 validation documentation | Choose SMCJ160CH when AEC-Q101 and documented ISO 7637-2 immunity are required |
Compared with SMBJ160A and TPSMD160, the SMCJ160CH provides superior energy handling (1500W vs. 600W/1500W), guaranteed AEC-Q101 qualification, and verified ISO 7637-2 compliance-making it the preferred choice for automotive power rail protection where transient severity and reliability are non-negotiable.

FAQ
What is the polarity configuration of the SMCJ160CH?
The SMCJ160CH is a unidirectional TVS diode, with cathode marked by a band on the DO-214AB package. It conducts only when the anode is negative relative to the cathode-ideal for protecting positive DC rails. This differs from bidirectional variants like SMCJ160CAH, which suppress transients in both directions.
Does the SMCJ160CH meet ISO 7637-2 requirements?
Yes, the SMCJ160CH is explicitly validated to meet ISO 7637-2 for Pulse 1 (inductive load disconnect), Pulse 2a/2b (supply interruption and load dump), and Pulse 3a/3b (capacitive coupling and ESD). This certification is documented in Taiwan Semiconductor's A2102 specification release and supports automotive design compliance.
What is the maximum clamping voltage of the SMCJ160CH under surge conditions?
The SMCJ160CH has a maximum clamping voltage (VC) of 287 V at 5.4 A peak impulse current (IPPM), measured using the standardized 10/1000μs double-exponential waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during transients.
Is the SMCJ160CH suitable for lead-free reflow soldering?
Yes, the SMCJ160CH features matte tin-plated leads compliant with J-STD-002 and rated for standard lead-free reflow profiles (peak temperature ≤260°C). Its moisture sensitivity level is J-STD-020 Level 1, meaning it can be stored indefinitely at ambient conditions without baking prior to assembly.
How does the SMCJ160CH differ from the SMCJ160AH variant?
The SMCJ160CH has a breakdown voltage range of 178–218 V and clamps at 287 V, while the SMCJ160AH specifies 178–197 V VBR and 259 V VC. The 'H' suffix denotes the standard version with higher clamping energy tolerance; the 'AH' offers tighter VBR distribution and lower VC for applications prioritizing lower let-through voltage over absolute energy capacity.
