Product details
Overview
3.0SMCJ150CA-13 from Diodes Incorporated is a bi-directional transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and signal interfaces. It delivers 3000W peak pulse power dissipation, clamps transients up to 243V at 12.3A (10×1000μs waveform), and maintains a 150V reverse standoff voltage with <5μA leakage at rated VRWM. It is deployed in industrial motor drives to safeguard IGBT gate drivers against EFT and lightning-induced surges.
For engineers reviewing the 3.0SMCJ150CA-13 datasheet, 3.0SMCJ150CA-13 pinout, 3.0SMCJ150CA-13 application, or 3.0SMCJ150CA-13 equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD, peak pulse current capability under IEC 61000-4-5 Level 4 stress, thermal derating above +25°C ambient, and SMC package solderability per MIL-STD-202.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, enabling robust protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown behavior and low capacitance (<50pF typical), critical for high-speed data line protection.
The device complies with IEC 61000-4-2 ESD immunity (30kV air/30kV contact) and meets JEDEC reliability standards for high-reliability applications. Its 150V VRWM and 243V VC support 125V nominal DC bus systems with ≥20% overvoltage safety margin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains 10×1000μs surges up to 12.3A without failure |
| Reverse Standoff Voltage (VRWM) | 150V - maximum continuous DC or RMS voltage before significant leakage |
| Clamping Voltage (VC @ IPP) | 243V @ 12.3A - limits transient voltage seen by downstream circuitry |
| Breakdown Voltage (VBR) | 167–184.6V @ 1mA - defines sharp avalanche onset for predictable clamping |
| ESD Rating | 30kV air / 30kV contact per IEC 61000-4-2 - protects against human handling events |
| Operating Temperature | −55°C to +150°C - supports under-hood automotive and industrial environments |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic body with UL 94V-0 flammability rating; terminals are matte tin-plated for reliable solderability per MIL-STD-202, Method 208. Bi-directional configuration has no polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Both terminals function identically; bidirectional clamping occurs regardless of voltage polarity |
Key Features
| Feature | Design Value |
|---|---|
| 3000W peak pulse power | Enables single-device protection against IEC 61000-4-5 4kV/2Ω surge waveforms on 125V DC rails |
| Glass-passivated die construction | Ensures long-term stability of breakdown voltage and low parameter drift over temperature and life |
| IEC 61000-4-2 ESD hardened | Eliminates need for external ESD diodes on front-panel interfaces or sensor inputs |
| RoHS-compliant, halogen-free "Green" design | Meets automotive and industrial environmental compliance mandates without sacrificing surge performance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150CA-13 | 2000W peak power, same VRWM/VC but lower IPP (9.2A vs. 12.3A) | Insufficient for IEC 61000-4-5 Level 4 (4kV) on 150V rails | Select only if system-level testing confirms 2000W suffices and board space is constrained |
| SMCJ150CA | Same electrical specs but non-tape-and-reel packaging (bulk); identical SMC footprint | No difference in circuit performance; affects automated assembly logistics | Choose when manual placement or low-volume prototyping eliminates need for reel packaging |
Compared with SMBJ150CA-13, this part provides +50% peak surge current headroom for demanding industrial surge standards; compared with SMCJ150CA, it offers factory-optimized tape-and-reel delivery for SMT production without electrical trade-offs.

FAQ
What is the maximum clamping voltage of the 3.0SMCJ150CA-13 under standard test conditions?
The maximum clamping voltage (VC) is 243V when subjected to a 10×1000μs surge waveform at 12.3A peak pulse current, measured per Figure 2 in DS30818 Rev. 18-2. This value is guaranteed across the full operating temperature range of −55°C to +150°C and defines the upper voltage limit imposed on protected circuitry during transient events.
Is the 3.0SMCJ150CA-13 suitable for automotive applications?
Yes - it is qualified to JEDEC reliability standards referenced in AEC-Q, manufactured in IATF 16949 certified facilities, and supports automotive-grade change control. While the base part is not AEC-Q200 certified, its automotive-qualified counterpart (e.g., 3.0SMCJ150CQ-13) is available and shares identical electrical characteristics and SMC packaging.
How does the bi-directional configuration affect PCB layout?
The bi-directional design eliminates polarity sensitivity: either terminal may connect to any node in a differential or floating system. No cathode band marking is present, and the SMC footprint requires symmetric pad geometry per Diodes' recommended layout (C = 6.90mm, G = 4.40mm). Thermal relief must accommodate 0.21g mass and 3000W pulse dissipation.
What is the leakage current specification at rated standoff voltage?
Maximum reverse leakage current (IR) is 5.0μA at VRWM = 150V and TA = +25°C, per the Electrical Characteristics table in DS30818. This low leakage ensures minimal impact on high-impedance bias networks and preserves efficiency in always-on power monitoring circuits without requiring additional filtering or compensation.
