Product details
Overview
3.0SMCJ90A-13 from Diodes Incorporated is a unidirectional 3000W surface-mount transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 90V reverse standoff voltage (VRWM), 100–110.5V breakdown voltage (VBR), 146V maximum clamping voltage (VC) at 20.5A peak pulse current (IPP), and IEC-61000-4-2 ESD immunity of 30kV (air/contact). It is used in industrial power supplies to protect downstream DC-DC converters from lightning-induced surges.
For engineers reviewing the 3.0SMCJ90A-13 datasheet, 3.0SMCJ90A-13 pinout, 3.0SMCJ90A-13 application, or 3.0SMCJ90A-13 equivalent, key selection criteria include clamping voltage margin relative to protected IC VMAX, peak pulse current handling under 10/1000μs waveform, thermal derating above +25°C ambient, and SMC package solderability per MIL-STD-202.
Technical Context
This TVS operates as a voltage-clamped crowbar device: under normal bias (≤90V), it draws ≤5μA leakage; when transient voltage exceeds 100V (VBR min), it avalanches into low-impedance conduction, limiting voltage across the protected line to ≤146V for up to 1000μs. Its glass-passivated junction ensures stable breakdown and low capacitance (<100pF typical).
The device is rated for single-pulse operation with 3000W peak power (10×1000μs), 300A surge current (8.3ms half-sine), and operates from –55°C to +150°C junction temperature. Derating begins linearly above +25°C ambient per Figure 1, reaching ~70% of PPK at +100°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |

|---|---|
Use Scenario: Protects 24V digital input channels in programmable logic controllers from induced surges on long field wiring. IC Role / Device Role: Unidirectional TVS placed between input terminal and ground, clamping transients before they reach optocoupler or MCU GPIO. Use Value: Limits voltage to ≤146V, ensuring optocoupler input stays below its 160V isolation rating and preventing latch-up in downstream logic. |
Use Scenario: Shields LIN bus transceiver supply rail (VBAT) in BCM modules from load-dump and jump-start events. IC Role / Device Role: Primary overvoltage clamp on 12V/24V supply line upstream of LDO regulators. Use Value: Absorbs 3000W surge energy while holding rail voltage below 150V, preserving regulator input SOA and avoiding system reset. |
| Telecom Power Feeds | Renewable Energy Inverter DC Link |
Use Scenario: Guards PoE-powered equipment front-end from Ethernet cable-induced surges and cross-talk coupling. IC Role / Device Role: Secondary-level TVS on 48V DC feed, coordinated with primary GDT or MOV stages. Use Value: Provides fast-response clamping (ns-scale) after coarse suppression, reducing residual overshoot to <150V for IEEE 802.3bt compliance. |
Use Scenario: Protects IGBT gate driver supply rails in solar string inverters exposed to grid-switching transients. IC Role / Device Role: Localized clamping on isolated 15V auxiliary supply feeding gate drivers. Use Value: Maintains clamping voltage ≤146V at 20.5A, preventing gate oxide damage during 10/1000μs grid fault events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ90A-13 (Diodes Inc.) | 600W rating, same VRWM/VBR/VC but lower IPP (10.3A vs. 20.5A) | Suitable only for lower-energy transients (IEC 61000-4-5 Level 2) | Select when board space is constrained and surge threat level is moderate |
| 1.5SMC90A (ON Semiconductor) | 1500W rating, identical VRWM/VBR/VC, but higher IR (10μA vs. 5μA) and no AEC-Q200 alignment | Lacks JEDEC high-reliability qualification; not recommended for automotive safety-critical nodes | Use in cost-sensitive industrial designs where full 3000W headroom is unnecessary |
Compared with SMBJ90A-13 and 1.5SMC90A, the 3.0SMCJ90A-13 delivers double the surge energy handling of SMBJ-grade devices and certified reliability for automotive-adjacent applications, making it optimal for high-threat environments where clamping margin and long-term stability are critical.

FAQ
What is the maximum clamping voltage of the 3.0SMCJ90A-13 under standard test conditions?
The maximum clamping voltage (VC) is 146V at 20.5A peak pulse current (IPP), measured using the standardized 10×1000μs waveform per IEC 61000-4-5. This value is guaranteed across the full operating temperature range and represents the upper limit of voltage seen by protected circuitry during worst-case surge events.
Is the 3.0SMCJ90A-13 suitable for automotive applications?
Yes - while the standard 3.0SMCJ90A-13 is JEDEC-qualified and RoHS-compliant, Diodes offers an automotive-grade variant (3.0SMCJ90AQ-13) qualified to AEC-Q200 with PPAP capability and manufactured in IATF 16949-certified facilities. For non-safety-critical automotive subsystems, the standard part is widely deployed with documented field reliability.
How does the SMC package affect thermal performance in PCB layout?
The SMC (DO-214AB) package requires 8.00mm² copper land area (0.013mm thick) per the datasheet to achieve rated 3000W pulse handling. Insufficient copper or poor thermal vias cause premature thermal runaway during repetitive surges; recommended layout includes ≥2 thermal vias per pad connected to internal ground planes.
Does the 3.0SMCJ90A-13 have bidirectional variants?
No - the "A" suffix denotes unidirectional configuration with cathode band marking. Bidirectional variants exist in the same family (e.g., 3.0SMCJ90CA-13), which lack polarity indicators and provide symmetrical clamping for AC-coupled or floating signal lines, but exhibit double the leakage current (10μA vs. 5μA) at VRWM.
