Product details
Overview
SMCJ6.0 from Taiwan Semiconductor is a unidirectional 1500W surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, with 6.67V minimum breakdown voltage, 8.15V maximum breakdown voltage at 10mA test current, and 11.4V maximum clamping voltage at 1000A peak pulse current - designed for automotive load-dump and inductive switching surge protection.
For engineers reviewing the SMCJ6.0 datasheet, SMCJ6.0 pinout, SMCJ6.0 application, or SMCJ6.0 equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD, peak pulse power handling under ISO 7637-2 Pulse 1/2a/2b/3a/3b waveforms, junction temperature derating above 25°C, and unidirectional polarity marking alignment with PCB layout.
Technical Context
The SMCJ6.0 operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its VBR range (6.67–8.15V), clamping transients to ≤11.4V at 1000A. Its glass-passivated junction enables sub-1ps response time and <1μA leakage above 10V working stand-off voltage.
Thermally, it features RθJA = 55°C/W and RθJC = 10°C/W, supporting continuous operation up to TJ = 150°C. It meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements in its molded DO-214AB case.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min / max | 6.67V / 8.15V at IT = 10mA - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| VWM | 10V - maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPPM | 11.4V at 1000A - peak clamped voltage limiting stress on downstream circuitry during surge events |
| PPK | 1500W (tp = 1ms) - single-pulse energy absorption capability per IEC 61000-4-5 and ISO 7637-2 |
| IR @ VWM | ≤6μA - low leakage ensures minimal standby power loss and signal integrity in high-impedance nodes |
| TJ max | 150°C - maximum junction temperature enabling use in under-hood automotive environments |
Pinout & Package
DO-214AB (SMC) surface-mount package with cathode band marking on one end; matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance; 0.210g typical weight; UL 94V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0 | Lower PPK = 400W; same VBR range but smaller DO-214AC (SMA) package | Not suitable for ISO 7637-2 Pulse 5a load-dump; limited to lower-energy ESD/EFT scenarios | Select SMAJ6.0 only when board space is critical and surge energy is ≤400W |
| SMCJ6.0A | Tighter VBR tolerance (6.67–7.37V vs. 6.67–8.15V); identical PPK, VC, and package | Same application scope but improved consistency in clamping onset across production lots | Choose SMCJ6.0A where tighter VBR distribution reduces design margin uncertainty |
Compared with SMAJ6.0 and SMCJ6.0A, the SMCJ6.0 offers the full 1500W surge rating of the SMC package while providing broader VBR tolerance than the 'A' variant - making it optimal for cost-sensitive automotive and industrial designs where absolute clamping precision is secondary to robust energy handling.

FAQ
What is the clamping voltage of SMCJ6.0 at its rated peak pulse current?
The SMCJ6.0 has a maximum clamping voltage (VC) of 11.4V at 1000A peak pulse current (IPPM), measured using the 10/1000μs waveform defined in IEC 61000-4-5. This value ensures protected circuits remain below critical overvoltage thresholds during standardized surge events, and is confirmed in the Electrical Specifications table on page 2 of the official S2104 datasheet.
Is SMCJ6.0 unidirectional or bidirectional, and how is polarity identified?
The SMCJ6.0 is a unidirectional TVS diode, with cathode indicated by a band on the DO-214AB (SMC) package body. Its electrical characteristics apply only in reverse bias - forward conduction occurs at ~3.5V per the datasheet. Bidirectional variants require the 'C' or 'CA' suffix (e.g., SMCJ6.0C), which are distinct part numbers with symmetrical breakdown in both directions.
Does SMCJ6.0 meet automotive surge immunity standards such as ISO 7637-2?
Yes, the SMCJ6.0 is explicitly rated to meet ISO 7637-2 Pulse 1 (inductive switch-off), Pulse 2a/2b (supply disconnection and coupled transients), and Pulse 3a/3b (capacitive coupling) requirements. This compliance is stated in the FEATURES section of the S2104 datasheet and validated through standardized surge testing per the specification's waveform definitions.
What is the maximum steady-state power dissipation (PD) of SMCJ6.0 at 25°C ambient?
The SMCJ6.0 has a steady-state power dissipation (PD) rating of 5W at TA = 25°C, as specified in the Absolute Maximum Ratings table. This value applies only to continuous DC or low-frequency conditions - transient surge handling (1500W) is strictly time-limited to 1ms pulses and must be derated per the Pulse Derating Curve (Fig.2) at higher ambient temperatures.
Can SMCJ6.0 be used in place of SMCJ6.0A, and what is the key difference?
The SMCJ6.0 can be used in place of SMCJ6.0A in most applications, but with wider VBR tolerance (6.67–8.15V vs. 6.67–7.37V). The SMCJ6.0A offers tighter breakdown consistency, while the SMCJ6.0 provides identical clamping performance (11.4V), package, and 1500W rating. No PCB changes are required, but design margin analysis should account for the broader VBR range of SMCJ6.0.
