Product details
Overview
SMCJ6.0H 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-level surge immunity in power supply input stages.
For engineers reviewing the SMCJ6.0H datasheet, SMCJ6.0H pinout, SMCJ6.0H application, or SMCJ6.0H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, thermal resistance values, and real-world ESD/transient protection use cases - all confirmed from Taiwan Semiconductor's official A2102 specification document.
Technical Context
The SMCJ6.0H 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 ensures stable breakdown and low leakage (<6µA at 10V).
Designed for automotive-grade reliability, it meets AEC-Q101 stress testing and ISO 7637-2 transient immunity standards including Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling). Junction temperature range is –55°C to +150°C with RθJA = 55°C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 6.67V / 8.15V @ 10mA - defines precise turn-on threshold for overvoltage detection |
| VWM | 10V - maximum continuous reverse operating voltage before leakage rises |
| VC @ IPPM | 11.4V @ 1000A - clamping voltage limiting downstream circuit stress during 1.0ms surge |
| PPK | 1500W - peak pulse power handling capability per 1ms waveform (Fig.5) |
| IR @ VWM | <6µA - ultra-low reverse leakage preserving standby power integrity |
| TJ max | +150°C - enables operation in under-hood automotive environments |
| RθJC | 10°C/W - supports thermal design with heatsink-integrated PCB layouts |
Pinout & Package
DO-214AB (SMC) surface-mount package: cathode-banded single-ended device with two terminals; matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path | Connected to system ground or low-side return in unidirectional TVS configuration |
| Cathode (banded end) | Reverse-biased clamping node | Connected to protected line (e.g., 12V rail); conducts avalanche current during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements (HTOL, TC, UHAST, etc.) |
| ISO 7637-2 compliance | Guarantees immunity to load-dump (Pulse 1), switching spikes (Pulse 2a/2b), and ESD-coupled noise (Pulse 3a/3b) |
| Glass passivated junction | Ensures long-term stability of VBR and low parameter drift across temperature and life cycles |
| Fast response time | <1.0ps rise from 0V to VBR min - critical for sub-nanosecond ESD event suppression |
| Moisture sensitivity level 1 | No floor-life limitation or baking required before reflow - simplifies SMT manufacturing |
Applications
| Automotive Power Input Protection | Industrial DC Power Rail Clamping |
|---|---|
Use Scenario: 12V battery-fed ECUs exposed to load-dump surges up to 120V per ISO 7637-2 Pulse 1. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and DC-DC converter input. Use Value: Clamps transients to 11.4V within nanoseconds, preventing damage to upstream regulators rated for ≤16V absolute max. | Use Scenario: 24V PLC I/O modules subjected to inductive kickback from solenoid drivers. IC Role / Device Role / Timing Role: Primary surge shunt on field-side power entry before filtering stage. Use Value: Absorbs 1500W pulses without degradation, maintaining <6µA leakage to avoid false triggering in low-power monitoring circuits. |
| Telecom Line Interface ESD Guard | Consumer Equipment AC/DC Adapter Input |
Use Scenario: Ethernet PHY power pins (3.3V/5V) requiring IEC 61000-4-2 Level 4 ESD protection. IC Role / Device Role / Timing Role: Secondary protection after common-mode choke, directly at IC VDD pin. Use Value: Sub-1ps response captures fast ESD arcs before they couple into sensitive analog front-ends. | Use Scenario: Secondary-side 12V output of wall adapters vulnerable to lightning-induced surges on mains-connected devices. IC Role / Device Role / Timing Role: Final-stage clamping device before linear regulator or microcontroller power input. Use Value: 10V working stand-off allows normal operation while clamping 1000A surges to safe 11.4V ceiling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0A | 600W rating, SMB package (smaller footprint), lower IPPM (100A vs. 1000A) | Suitable for consumer-grade ESD-only protection; insufficient for ISO 7637-2 Pulse 1 load-dump | Select SMCJ6.0H when automotive or industrial surge immunity beyond 600W is required. |
| 1.5KE6.8A | Through-hole DO-201 package, same 1500W rating but slower response (>1ns), higher VC (11.5V) | Legacy designs with through-hole assembly; not suitable for high-density SMT layouts | Choose SMCJ6.0H for automated SMT placement, AEC-Q101 compliance, and tighter VC tolerance. |
Compared with SMBJ6.0A and 1.5KE6.8A, the SMCJ6.0H uniquely combines 1500W surge capacity, sub-1ps response, AEC-Q101 qualification, and DO-214AB SMT compatibility - making it the only option among the three validated for automotive power rail protection per ISO 7637-2.

FAQ
What is the clamping voltage of the SMCJ6.0H at its rated peak pulse current?
The SMCJ6.0H has a maximum clamping voltage (VC) of 11.4V at 1000A peak pulse current (IPPM), measured under the 10/1000μs waveform defined in Fig.5 of the datasheet. This value ensures downstream ICs with 12V absolute maximum ratings remain protected during worst-case transients. The SMCJ6.0H achieves this with minimal voltage overshoot due to its fast avalanche response.
Is the SMCJ6.0H suitable for bidirectional transient suppression?
No - the SMCJ6.0H is unidirectional only, indicated by the absence of "C" or "CA" suffix. For bidirectional operation, select SMCJ6.0CH or SMCJ6.0CAH variants, which provide symmetrical clamping in both polarities. Using SMCJ6.0H in reverse-biased configurations risks permanent breakdown since its anode is not rated for sustained forward conduction beyond 3.5V.
Does the SMCJ6.0H meet automotive qualification standards?
Yes - the SMCJ6.0H is explicitly AEC-Q101 qualified and certified to withstand automotive-grade stress tests including temperature cycling, humidity bias, and high-temperature operating life. It also complies with ISO 7637-2 Pulse 1 (load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling), making it suitable for engine control units and body electronics.
What is the maximum steady-state power dissipation for the SMCJ6.0H?
The SMCJ6.0H 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 reverse bias conditions - not transient events. In normal operation, reverse leakage remains below 6µA at 10V, resulting in negligible static power loss. The SMCJ6.0H relies on short-duration pulse handling (1500W) rather than continuous power rating.
How does the SMCJ6.0H compare to the SMCJ6.0AH variant?
The SMCJ6.0AH offers tighter breakdown voltage tolerance (6.67–7.37V vs. 6.67–8.15V for SMCJ6.0H) and slightly lower clamping voltage (10.3V vs. 11.4V at 1000A), achieved via enhanced process control. Both share identical package, thermal specs, and AEC-Q101 qualification. Choose SMCJ6.0H for cost-sensitive applications where broader VBR spread is acceptable; select SMCJ6.0AH when precise clamping threshold and margin-critical designs demand tighter parametric control.
