Product details
Overview
SMCJ5.0CH from Taiwan Semiconductor is a unidirectional 1500W surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, with 6.4V minimum breakdown voltage, 9.6V maximum clamping voltage at 1000A peak pulse current, and <1.0ps response time-designed to protect automotive-grade power rails and I/O interfaces against ESD and ISO 7637-2 load-dump transients.
For engineers reviewing the SMCJ5.0CH datasheet, SMCJ5.0CH pinout, SMCJ5.0CH application, or SMCJ5.0CH equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance values, clamping performance under 10/1000μs surge, and direct alternatives for automotive and industrial overvoltage protection design.
Technical Context
The SMCJ5.0CH uses a glass-passivated silicon junction optimized for fast transient suppression in unidirectional configurations. It meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b waveforms and sustains 1000A peak impulse current (IPPM) with 9.6V clamping voltage (VC), while maintaining ≤1μA reverse leakage above 10V working stand-off voltage (VWM = 5V).
Its thermal design supports operation up to TJ = +150°C, with RθJA = 55°C/W and RθJC = 10°C/W, enabling reliable placement on standard FR-4 PCBs without forced airflow-critical for under-hood automotive modules and industrial PLC I/O protection circuits.
Key Specifications

| VBR (min) | 6.4 V @ 10 mA - Ensures reliable triggering above system nominal rail |
| VC @ IPPM | 9.6 V @ 1000 A - Limits downstream IC stress during 10/1000μs surge events |
| PPK | 1500 W - Peak pulse power handling per single non-repetitive transient |
| IR @ VWM | <5 μA - Negligible leakage impact on low-power sensor or CAN bus bias networks |
| TJ max | +150 °C - Supports under-hood automotive deployment without derating |
| RθJA | 55 °C/W - Enables thermal management on 2-layer boards with minimal copper area |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Lower PPK (400W), SMA package (smaller footprint, higher RθJA = 85°C/W) | Suitable for space-constrained consumer designs with lower surge exposure | Select if board area is critical and ISO 7637-2 compliance is not required |
| 1.5KE5.0A | Through-hole TO-218 package, same VBR/VC specs but slower response (~1ns), no AEC-Q101 | Used in legacy industrial power supplies where automated SMT is not available | Select only for manual assembly or retrofit scenarios requiring through-hole mounting |
Compared with SMAJ5.0A and 1.5KE5.0A, the SMCJ5.0CH provides 3.75× higher surge power rating, AEC-Q101 qualification, and superior thermal performance in SMT form-making it the preferred choice for new automotive and high-reliability industrial designs requiring robust 10/1000μs transient immunity.

FAQ
What is the clamping voltage of SMCJ5.0CH at its rated peak pulse current?
The SMCJ5.0CH has a maximum clamping voltage (VC) of 9.6 V at 1000 A peak pulse current (IPPM), measured under the standardized 10/1000 μs double-exponential waveform per IEC 61000-4-5. This value ensures protected circuits remain within safe operating limits during severe transients, and is confirmed in the Electrical Specifications table on page 2 of the official TSC datasheet revision A2102.
Is SMCJ5.0CH suitable for bidirectional transient suppression?
No, the SMCJ5.0CH is a unidirectional TVS diode, indicated by the "H" suffix and absence of "CH" or "CAH" designation. For bidirectional operation, TSC specifies SMCJ5.0CH (with "CH") or SMCJ5.0CAH-both explicitly rated for symmetrical clamping in either polarity. Using SMCJ5.0CH in reverse-biased configuration risks permanent junction failure due to lack of reverse breakdown specification.
Does SMCJ5.0CH meet automotive qualification standards?
Yes, the SMCJ5.0CH is AEC-Q101 qualified and tested per the full stress test schedule-including HTGB, HTRB, temperature cycling, and ESD-making it approved for use in automotive powertrain, chassis, and body electronics. Its compliance with ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b further validates suitability for vehicle-level EMC requirements.
What is the maximum steady-state power dissipation for SMCJ5.0CH?
The SMCJ5.0CH has a steady-state power dissipation (PD) rating of 5 W at TA = 25°C, as specified in the Absolute Maximum Ratings table. This value applies only to continuous DC or low-frequency conditions-not transient events-and must be derated linearly above 25°C using the RθJA = 55°C/W thermal resistance to avoid exceeding TJ(max) = +150°C.
How does the marking code "GDD" relate to SMCJ5.0CH?
The marking code "GDD" appears on the physical SMCJ5.0CH device per the Electrical Specifications table and identifies the specific variant with VBR(min) = 6.4 V, VBR(max) = 7.3 V, and VC = 9.6 V. It is distinct from SMCJ5.0AH (marked "GDE"), which has tighter VBR tolerance (6.4–7.0 V) and slightly higher VC (9.2 V), confirming that "GDD" uniquely corresponds to the base SMCJ5.0CH part number in production traceability.
