Product details
Overview
3.0SMCJ9.0CA-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 9.0 V reverse standoff voltage (VRWM), 15.4 V maximum clamping voltage (VC) at 194.8 A peak pulse current, and 3000 W peak pulse power dissipation per 10/1000 µs waveform. Used in industrial power supplies and automotive body control modules to suppress ESD and lightning-induced surges.
For engineers reviewing the 3.0SMCJ9.0CA-13 datasheet, 3.0SMCJ9.0CA-13 pinout, 3.0SMCJ9.0CA-13 application, or 3.0SMCJ9.0CA-13 equivalent, key selection criteria include clamping voltage margin relative to protected IC VCC, IEC-61000-4-2 ESD robustness (30 kV air/30 kV contact), thermal derating above +25°C, and SMC package solderability per MIL-STD-202.
Technical Context
This bi-directional TVS operates symmetrically across both polarities with no cathode band marking, enabling bidirectional surge suppression without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<10 µA at VRWM), critical for low-power sensor interfaces and always-on circuits.
The device complies with IEC-61000-4-2 Level 4 ESD immunity (30 kV air, 30 kV contact) and supports HBM (8 kV), CDM (1 kV), and MM (800 V) standards. Thermal performance is rated for continuous operation from –55°C to +150°C junction temperature, with pulse derating following Fig. 1 in DS30818 Rev. 18–2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000 W - sustains single 10/1000 µs transients up to this level without failure |
| Reverse Standoff Voltage | 9.0 V - maximum continuous DC or RMS voltage before significant leakage begins |
| Clamping Voltage | 15.4 V @ 194.8 A - limits transient voltage seen by downstream circuitry during surge events |
| ESD Rating | 30 kV air / 30 kV contact per IEC-61000-4-2 - protects against human-handling electrostatic discharge |
| Operating Temperature | –55°C to +150°C - suitable for under-hood automotive and industrial environments |
| Package | SMC (DO-214AB) - surface-mount footprint with 7.75–8.13 mm body length and 2.75–3.18 mm thickness |
Pinout & Package
3.0SMCJ9.0CA-13 uses the SMC (DO-214AB) package: molded plastic body, matte tin-plated leads, moisture sensitivity level 1, and approximate weight of 0.21 g. Bi-directional configuration means both terminals are electrically symmetrical - no polarity marking required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals conduct identically during positive or negative surges; no orientation dependency on PCB |
| Case (body) | Thermal mass & mechanical anchor | Plastic body provides insulation while enabling heat dissipation via copper land (8.00 mm² recommended) |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns |
| Glass-passivated die | Ensures long-term stability of breakdown voltage and low parameter drift over temperature and life |
| Lead-free & RoHS-compliant | Meets EU Directive 2015/863/EU with <900 ppm Br, <900 ppm Cl, <1000 ppm Sb - supports green manufacturing |
| High surge current capability | 194.8 A peak pulse current (IPP) enables protection against severe load-dump or inductive-switching events |
Applications
| Industrial Power Input Protection | Automotive Body Control Module |
|---|---|
Use Scenario: 24 V DC input rail in programmable logic controllers exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Primary clamping element placed upstream of DC-DC converters and microcontrollers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ9.0CA-13 | Same VRWM and VC, but 600 W peak power (vs. 3000 W); SMB package (smaller footprint, lower thermal mass) | Suitable only for lower-energy transients (e.g., board-level ESD), not load dump or lightning | Select when space-constrained and surge energy is limited to <600 W |
| 1.5SMCJ9.0CA | Same SMC package and 9.0 V VRWM, but 1500 W peak power (half the rating); identical pinout and mounting | Acceptable for moderate-duty industrial controls but insufficient for automotive load dump per ISO 16750-2 | Choose if cost-sensitive and worst-case surge energy is confirmed ≤1500 W |
Compared with SMBJ9.0CA-13 and 1.5SMCJ9.0CA, the 3.0SMCJ9.0CA-13 delivers 5× and 2× higher peak power respectively - essential for protecting high-reliability systems where surge energy exceeds 1500 W and thermal recovery between events is critical.

FAQ
What is the maximum clamping voltage of 3.0SMCJ9.0CA-13 at its rated peak pulse current?
The maximum clamping voltage (VC) is 15.4 V when subjected to a 10/1000 µs waveform at 194.8 A peak pulse current (IPP), measured per JEDEC standard test conditions. This value defines the upper voltage limit imposed on protected circuitry during worst-case surge events and remains stable across the full operating temperature range of –55°C to +150°C.
Is 3.0SMCJ9.0CA-13 unidirectional or bidirectional, and how is polarity identified?
3.0SMCJ9.0CA-13 is a bi-directional TVS diode with symmetrical breakdown behavior in both polarities. It carries no cathode band or polarity marking - the device functions identically regardless of terminal orientation on the PCB. This eliminates assembly errors and simplifies layout for AC-coupled or floating signal paths.
Does 3.0SMCJ9.0CA-13 meet automotive qualification standards?
While the base 3.0SMCJ9.0CA-13 is qualified to JEDEC high-reliability standards and manufactured in IATF 16949-certified facilities, it is not AEC-Q200 qualified. For automotive applications requiring formal AEC-Q200 certification, Diodes offers the Q-suffix variant (e.g., 3.0SMCJ9.0CAQ-13), which undergoes additional stress testing and PPAP documentation.
What is the recommended PCB pad layout for optimal thermal and electrical performance?
Diodes recommends an 8.00 mm² copper land area (0.013 mm thick) per terminal to support thermal dissipation during 3000 W pulses. The official SMC pad layout specifies X = 2.50 mm, Y = 3.30 mm, X1 = 9.40 mm, C = 6.90 mm, and G = 4.40 mm (all in mm). Use solder mask defined pads and avoid thermal reliefs on high-current paths to maintain clamping consistency.
