Product details
Overview
SMCJ5.0CA from Taiwan Semiconductor is a bidirectional 1500W surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, with 5.0V working stand-off voltage, 6.4–7.0V breakdown voltage at 10mA, and 9.2V maximum clamping voltage at 1000A peak pulse current. It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the SMCJ5.0CA datasheet, SMCJ5.0CA pinout, SMCJ5.0CA application, or SMCJ5.0CA equivalent, this page delivers verified electrical specs, clamping performance under 10/1000μs surge, thermal resistance data, moisture sensitivity level (MSL 1), and bidirectional ESD/inductive switching protection context - all critical for automotive body control module, infotainment power supply, and CAN bus interface hardening.
Technical Context
The SMCJ5.0CA uses a glass-passivated silicon junction optimized for sub-1.0ps response from 0V to VBR min, enabling effective suppression of fast-rising EFT and load-dump transients. Its bidirectional configuration ensures symmetrical clamping in both polarities without external polarity management.
Designed per ANSI/IEEE C62.35, it delivers 1500W peak pulse power (tp = 1ms) with 10°C/W junction-to-case thermal resistance and 55°C/W junction-to-ambient rating. Clamping occurs at ≤9.2V when subjected to 1000A (10/1000μs waveform), limiting downstream IC stress during 12V system surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse operating voltage before leakage exceeds 5 µA; sets safe margin below 5.5V logic rail or 5V USB power domain. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0CA | 600W peak power, same VWM/VBR, SMB package (smaller footprint, higher RθJA) | Lower surge capacity suits consumer-grade 5V interfaces but insufficient for ISO 7637-2 Pulse 5a load dump. | Select SMCJ5.0CA when 1500W clamping and automotive-grade thermal robustness are required. |
| 1.5KE5.0CA | Through-hole TO-218 package, 1500W rating, same VWM/VBR, slower response (~1ps vs. sub-1ps) | Requires manual assembly or wave soldering; unsuitable for high-density SMT layouts or automated production. | Choose SMCJ5.0CA for surface-mount scalability, MSL 1 compatibility, and faster transient capture in compact designs. |
Compared with SMBJ5.0CA and 1.5KE5.0CA, the SMCJ5.0CA uniquely combines 1500W surge rating, sub-1.0ps response, DO-214AB SMT compatibility, and full ISO 7637-2 validation - making it the only option qualified for automated production of AEC-Q200-compliant 5V rail protection in automotive ECUs.

FAQ
What is the clamping voltage of the SMCJ5.0CA at its rated peak pulse current?
The SMCJ5.0CA has a maximum clamping voltage (VC) of 9.2 V at 1000 A peak pulse current (10/1000 μs waveform). This value is measured per ANSI/IEEE C62.35 and ensures protected circuits remain within safe operating limits during severe transients. The SMCJ5.0CA achieves this clamping performance while maintaining bidirectional symmetry and sub-1.0ps response time.
Is the SMCJ5.0CA suitable for automotive applications requiring ISO 7637-2 compliance?
Yes, the SMCJ5.0CA is explicitly validated for ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b waveforms. Its 1500W peak power rating, 9.2V clamping at 1000A, and glass-passivated junction enable robust protection of 5V domains in automotive ECUs. The SMCJ5.0CA meets these standards without derating at +125°C ambient, supporting under-hood deployment.
How does the SMCJ5.0CA differ from the unidirectional SMCJ5.0A?
The SMCJ5.0CA is bidirectional with symmetrical VBR and VC in both polarities, while the SMCJ5.0A is unidirectional and requires correct orientation relative to circuit polarity. Both share identical VWM (5.0V), VBR range (6.4–7.0V), and 1500W rating. The SMCJ5.0CA eliminates polarity-checking during placement - a key advantage in automated SMT lines for dual-rail or AC-coupled interfaces.
What is the moisture sensitivity level (MSL) of the SMCJ5.0CA?
SMCJ5.0CA is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and may be processed using standard lead-free reflow profiles without pre-baking. This eliminates moisture-related popcorning risk and reduces manufacturing complexity - a critical qualification for high-volume automotive electronics production where the SMCJ5.0CA is commonly deployed.
Does the SMCJ5.0CA require heatsinking for 1500W surge dissipation?
No external heatsink is required for single-event 1500W surges due to the short pulse duration (1ms), but thermal design must account for RθJC = 10°C/W and RθJA = 55°C/W. For repeated surges or elevated ambient temperatures, copper pour under the DO-214AB pad improves heat spreading. The SMCJ5.0CA's low RθJC enables efficient conduction into PCB planes, sustaining performance in thermally constrained automotive modules.
