Product details
Overview
3.0SMCJ15CA-13 from Diodes Incorporated is a bi-directional transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 15.0 V reverse standoff voltage (VRWM), 24.2 V maximum clamping voltage (VC) at 124.0 A peak pulse current (IPP), and 3000 W peak pulse power dissipation per 10/1000 μs waveform - deployed in industrial motor drives to safeguard IGBT gate drivers against inductive switching transients.
For engineers reviewing the 3.0SMCJ15CA-13 datasheet, 3.0SMCJ15CA-13 pinout, 3.0SMCJ15CA-13 application, or 3.0SMCJ15CA-13 equivalent, this part is selected for high-energy surge immunity in 24 V and 48 V embedded power systems where low clamping voltage, bi-directional symmetry, and JEDEC-qualified reliability are mandatory design requirements.
Technical Context
This TVS operates as a voltage-clamped shunt protector with avalanche breakdown behavior, triggered when transient voltage exceeds its 16.7–18.5 V breakdown range (VBR @ IT = 1.0 mA). Its bi-directional configuration enables symmetrical clamping on both polarities without external polarity management.
Thermally rated for continuous operation from –55 °C to +150 °C junction temperature, it delivers stable clamping performance under repeated 8.3 ms half-sine surges up to 300 A (IFSM), with derating above +25 °C ambient per Fig. 1 - validated per IEC-61000-4-2 (30 kV air/contact ESD), HBM (8 kV), CDM (1 kV), and MM (800 V) standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000 W - sustains single 10/1000 μs transients up to 124 A without failure |
| Reverse Standoff Voltage | 15.0 V - defines maximum continuous DC operating voltage before leakage exceeds 5 μA |
| Clamping Voltage | 24.2 V @ 124 A - limits transient voltage seen by downstream ICs during surge events |
| Breakdown Voltage | 16.7–18.5 V @ 1.0 mA - ensures reliable turn-on margin above VRWM for robust triggering |
| ESD Rating | 30 kV air / 30 kV contact per IEC-61000-4-2 - protects against field-induced electrostatic discharge |
| Operating Temperature | –55 °C to +150 °C - supports under-hood automotive and industrial control cabinet deployments |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic body with UL 94V-0 flammability rating; terminals matte tin-plated for solderability per MIL-STD-202, Method 208; bi-directional variant has no polarity indicator.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional surge path | Either terminal serves as input or return - no cathode band; identical clamping in both directions |
| Case (body) | Thermal mass & mechanical anchor | 0.21 g weight; mounted on 8.00 mm² copper land for thermal derating compliance |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15CA-13 | Same VRWM and VC, but 600 W peak power (vs. 3000 W); SMB package (smaller thermal mass) | Limited to lower-energy surges (e.g., board-level ESD only); unsuitable for 24 V rail load dump | Select only for space-constrained designs where surge energy remains below 600 W capability |
| 1.5SMC15CA | Same VRWM/VC specs but 1500 W peak power; legacy SMC package with different marking and moisture sensitivity (MSL 2) | Requires pre-bake before reflow; not qualified to latest JEDEC high-reliability baseline | Use only if legacy BOM continuity is required and MSL 2 process controls are in place |
Compared with SMBJ15CA-13 and 1.5SMC15CA, the 3.0SMCJ15CA-13 delivers 5× higher surge energy absorption and MSL 1 process compatibility - making it the sole choice for industrial-grade 24 V/48 V power rail protection requiring sustained 3000 W clamping without thermal derating penalties.

FAQ
What is the maximum clamping voltage of the 3.0SMCJ15CA-13 under standardized surge conditions?
The maximum clamping voltage is 24.2 V, measured at 124.0 A peak pulse current using the 10 × 1000 μs waveform defined in IEC 61000-4-5. This value is guaranteed across the full operating temperature range (–55 °C to +150 °C) and represents the upper limit of voltage imposed on protected circuitry during worst-case transient events.
Is the 3.0SMCJ15CA-13 unidirectional or bidirectional, and how is polarity indicated?
The 3.0SMCJ15CA-13 is a bi-directional TVS diode with symmetrical clamping characteristics on both terminals. Unlike unidirectional variants in the same family, it carries no cathode band marking - its top-view package is featureless, confirming bidirectional functionality per Diodes' marking code "DEM" and datasheet designation "(C)A".
Does this TVS require special PCB layout considerations for thermal performance?
Yes - the device must be mounted on minimum 8.00 mm² copper land areas (0.013 mm thick) to meet its 3000 W pulse rating. Derating begins above +25 °C ambient per Figure 1; insufficient copper area reduces peak surge capability and risks parametric shift or catastrophic failure during repeated transients.
Can the 3.0SMCJ15CA-13 replace older 1.5SMC15CA devices in existing designs?
Yes, it is a direct footprint-compatible upgrade: both use SMC (DO-214AB) packaging with identical pad layout and mechanical dimensions. The 3.0SMCJ15CA-13 offers double the peak power (3000 W vs. 1500 W), improved MSL rating (Level 1 vs. Level 2), and updated JEDEC qualification - requiring no layout change but delivering significantly enhanced surge resilience.
