Product details
Overview
3.0SMCJ90CA-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 146V at 20.5A (10/1000μs waveform), and features a 90V reverse standoff voltage with ±5% tolerance. Used in industrial motor drives to protect IGBT gate drivers from inductive switching spikes.
For engineers reviewing the 3.0SMCJ90CA-13 datasheet, 3.0SMCJ90CA-13 pinout, 3.0SMCJ90CA-13 application, or 3.0SMCJ90CA-13 equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD, peak pulse current capability under system-level surge waveforms (IEC 61000-4-5), and thermal derating behavior above +25°C ambient.
Technical Context
This TVS operates as a voltage-clamping device using avalanche breakdown in silicon PN junctions. Its bi-directional configuration enables symmetric suppression of positive and negative transients without polarity sensitivity-critical for AC-coupled data lines or floating bus systems.
It complies with IEC 61000-4-2 ESD immunity (30kV air/30kV contact) and meets JEDEC high-reliability standards. The glass-passivated die construction ensures stable leakage performance and robust surge endurance across -55°C to +150°C operating temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains single 10/1000μs surges up to 20.5A without failure |
| Reverse Standoff Voltage | 90V - maximum continuous DC or RMS voltage before significant leakage begins |
| Clamping Voltage | 146V @ 20.5A - upper voltage limit imposed on protected circuit during worst-case surge |
| Breakdown Voltage | 100–110.5V @ 1mA - guaranteed avalanche initiation range for reliable triggering |
| Leakage Current | ≤5μA @ 90V - negligible standby power loss and minimal impact on high-impedance sensing nodes |
| ESD Rating | 30kV (air/contact) per IEC 61000-4-2 - protects against human-handling events without external shielding |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic body with UL 94V-0 flammability rating; terminals are matte tin-plated for solderability per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | Connects to line requiring protection; forms symmetrical conduction path with cathode |
| Cathode | Transient current entry (positive polarity) | Connects to line requiring protection; identical electrical role to anode in bi-directional operation |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional clamping | Enables single-device protection of AC signals or ungrounded buses without polarity concerns |
| Glass-passivated die | Ensures long-term stability of breakdown voltage and low parametric drift over temperature and life |
| JEDEC high-reliability qualification | Validated for mission-critical applications including industrial control and automotive subsystems |
| RoHS-compliant & halogen-free | Meets environmental compliance requirements for global electronics manufacturing (Br+Cl <1500ppm, Sb <1000ppm) |
Applications
| Industrial Motor Drives | Telecom Power Feeds |
|---|---|
Use Scenario: Protecting gate driver ICs in 3-phase inverter stages from turn-off voltage spikes induced by parasitic inductance. IC Role / Device Role / Timing Role: Clamps transient overshoots exceeding 120V rail to ≤146V within nanoseconds, preventing gate oxide rupture. Use Value: Eliminates need for snubber RC networks, reducing board area and component count while maintaining IGBT reliability. | Use Scenario: Safeguarding PoE (Power over Ethernet) injectors against lightning-induced surges on 48V DC feed lines. IC Role / Device Role / Timing Role: Absorbs 10/1000μs surges up to 3000W without degradation, preserving IEEE 802.3af/at compliance. Use Value: Enables Class 4 PoE+ operation with single-stage protection, avoiding cascaded TVS stages that increase insertion loss. |
| Automotive Body Control Modules | Renewable Energy Inverters |
Use Scenario: Shielding LIN bus transceivers from load-dump transients during battery disconnect events in 12V vehicle networks. IC Role / Device Role / Timing Role: Responds within <1ns to clamp 120V/100ms load dump to safe levels below transceiver absolute maximum ratings. Use Value: Meets ISO 7637-2 Pulse 5a requirements without additional series impedance, preserving signal integrity. | Use Scenario: Protecting DC-link monitoring circuits in solar microinverters exposed to grid-switching transients. IC Role / Device Role / Timing Role: Limits voltage excursions on 400V DC bus sense resistors during rapid grid reconnection events. Use Value: Maintains measurement accuracy by preventing saturation of downstream op-amps during 1kV surge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ90CA | 600W peak power, same 90V standoff and 146V clamping, SMB package (smaller footprint) | Limited to lower-energy surges; unsuitable for IEC 61000-4-5 Level 3/4 testing | Select when space-constrained and surge energy is ≤600W (e.g., USB-C port ESD only) |
| 1.5SMCJ90CA | 1500W peak power, identical voltage ratings, same SMC package | Half the surge handling capacity; requires parallel placement for 3000W compliance | Choose when cost sensitivity outweighs board space, and dual-device layout is acceptable |
Compared with SMBJ90CA and 1.5SMCJ90CA, the 3.0SMCJ90CA-13 provides double the surge energy margin of the latter and five times that of the former-enabling single-device compliance with industrial IEC 61000-4-5 surge immunity requirements without layout compromise.

FAQ
What does the "CA" suffix indicate in 3.0SMCJ90CA-13?
The "CA" denotes a bi-directional configuration: "C" indicates the SMCJ series, and "A" specifies bi-directional polarity. Unlike "A"-suffixed uni-directional parts (e.g., 3.0SMCJ90A), this device has no cathode band and clamps equally for both polarities-ideal for AC or floating signal lines.
Can 3.0SMCJ90CA-13 be used in place of a uni-directional TVS like 3.0SMCJ90A?
Yes, but only if the circuit lacks DC bias or ground reference asymmetry. Bi-directional devices exhibit identical clamping in both directions, whereas uni-directional types conduct only during reverse-bias surges. Substitution requires verifying that forward conduction during normal operation won't cause unintended current paths or loading.
How does thermal derating affect its 3000W rating above +25°C?
Per Figure 1 in DS30818, peak pulse power drops linearly: at +85°C ambient, it's rated for ~70% (2100W); at +125°C, ~40% (1200W). This reflects junction temperature limits-designers must ensure PCB copper area and airflow maintain TJ ≤ +150°C during surge events to avoid permanent degradation.
Is 3.0SMCJ90CA-13 qualified for automotive applications?
No-the standard "-13" variant is commercial-grade. For automotive use, Diodes offers Q-suffix versions (e.g., 3.0SMCJ90CAQ-13) qualified to AEC-Q101, manufactured in IATF 16949 facilities, and PPAP-capable. These undergo additional stress testing and change control not present in the base part.
