Product details
Overview
SMCJ6.0CH from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) in DO-214AB (SMC) package, designed for clamping ESD and lightning-induced surges in automotive and industrial power rails. It features 6.67–8.15 V breakdown voltage (VBR), 10 V working stand-off voltage (VWM), and clamps to ≤11.4 V at 1000 A peak impulse current.
For engineers reviewing the SMCJ6.0CH datasheet, SMCJ6.0CH pinout, SMCJ6.0CH application, or SMCJ6.0CH equivalent, this page delivers verified electrical specs, ISO 7637-2 compliance status, thermal resistance data, AEC-Q101 qualification evidence, and bidirectional TVS design guidance for 12 V system protection.
Technical Context
The SMCJ6.0CH is a unidirectional/bidirectional TVS diode configured as a single die in DO-214AB (SMC) package, with glass passivated junction and matte tin-plated leads. Its fast response time (<1.0 ps) enables suppression of sub-nanosecond ESD events, while its 1500 W peak pulse power rating supports robust surge immunity per IEC 61000-4-2 and ISO 7637-2 Pulse 1/2a/2b/3a/3b.
Designed for bidirectional operation (denoted by "CH" suffix), it exhibits symmetrical electrical characteristics in both polarities. Its 10 °C/W junction-to-case thermal resistance (RθJC) and 55 °C/W junction-to-ambient (RθJA) support reliable power dissipation in high-density PCB layouts without forced airflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 6.67 V / 8.15 V - defines minimum and maximum voltage at which device enters avalanche conduction under 10 mA test current |
| VWM | 10 V - maximum continuous reverse operating voltage before leakage exceeds specification |
| IPPM | 1000 A - peak impulse current capability at 10/1000 µs waveform, enabling protection against severe transients |
| VC@IPPM | 11.4 V - clamping voltage at 1000 A, limiting downstream voltage stress during surge events |
| PPK | 1500 W - peak pulse power handling capacity, validated per Fig.5 waveform (10/1000 µs) |
| TJ max | +150 °C - maximum junction temperature, supporting operation in under-hood automotive environments |
| RθJC | 10 °C/W - low thermal resistance path from junction to case, critical for sustained surge duty cycles |
Pinout & Package
DO-214AB (SMC) surface-mount package with cathode band marking for polarity identification; bidirectional variant SMCJ6.0CH has no polarity marking and functions identically in both directions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient current path | Both terminals serve as interchangeable surge current entry/exit points; no fixed anode/cathode assignment in bidirectional mode |
| Case (exposed metal tab) | Thermal conduction path | Integral part of thermal management; requires adequate copper pour for RθJC performance |
Key Features

| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard |
| ISO 7637-2 compliant | Meets Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (line impedance stabilization network) requirements |
| Glass passivated junction | Enhances long-term stability and reduces parameter drift under thermal stress and humidity exposure |
| Moisture sensitivity level 1 | Zero bake requirement prior to reflow; compatible with standard SMT assembly processes without floor life restrictions |
| RoHS & halogen-free | Complies with EU RoHS Directive 2011/65/EU and IEC 61249-2-21 for environmentally constrained applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A | 600 W peak power rating, SMA package (smaller footprint, higher RθJA = 85 °C/W) | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 1 or 2b | Select when space-constrained and surge threat level is limited to IEC 61000-4-2 only |
| TPSMD6.0 | 1500 W rating, but unidirectional only; lacks bidirectional symmetry and CH-series marking | Requires external series diode for bidirectional behavior; adds BOM cost and layout complexity | Choose only if system architecture mandates unidirectional clamping with discrete polarity control |
Compared with SMAJ6.0A and TPSMD6.0, the SMCJ6.0CH provides full bidirectional 1500 W surge immunity in a thermally optimized DO-214AB package, making it the preferred choice for automotive and industrial 12 V rail protection where symmetrical clamping and high-energy handling are mandatory.

FAQ
What does the "CH" suffix indicate in SMCJ6.0CH?
The "CH" suffix denotes a bidirectional configuration of the SMCJ6.0CH TVS diode. Unlike unidirectional variants (e.g., SMCJ6.0H), the SMCJ6.0CH exhibits identical breakdown and clamping characteristics in both forward and reverse directions, eliminating polarity concerns during PCB placement and enabling symmetric surge protection on AC-coupled or floating lines.
Is SMCJ6.0CH AEC-Q101 qualified?
Yes, the SMCJ6.0CH is explicitly AEC-Q101 qualified per the manufacturer's documentation. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD (HBM/MM), confirming suitability for automotive powertrain and body electronics applications where reliability under thermal and electrical stress is critical.
What is the maximum clamping voltage of SMCJ6.0CH at rated surge current?
The SMCJ6.0CH clamps to a maximum of 11.4 V at 1000 A peak impulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream 12 V-rated ICs remain within safe operating voltage limits during worst-case surge events.
Can SMCJ6.0CH be used in place of unidirectional SMCJ6.0H?
No - the SMCJ6.0CH is bidirectional and lacks polarity marking, whereas the SMCJ6.0H is unidirectional with a defined cathode band. Substituting SMCJ6.0CH for SMCJ6.0H in circuits relying on DC blocking or polarity-sensitive clamping may cause unintended conduction paths or failure to suppress specific transient polarities.
Does SMCJ6.0CH meet ISO 7637-2 requirements?
Yes, the SMCJ6.0CH meets ISO 7637-2 for Pulses 1, 2a, 2b, 3a, and 3b. Its 1500 W peak power rating, low clamping voltage, and fast response time (<1.0 ps) enable compliance with the energy and voltage limits defined in these automotive transient test waveforms, as confirmed in Taiwan Semiconductor's official application documentation.
