Product details
Overview
3.0SMCJ22CA-13 from Diodes Incorporated is a bi-directional 3000W surface-mount transient voltage suppressor (TVS) designed for robust overvoltage protection on DC power rails and signal lines. It features a 22V reverse standoff voltage (VRWM), 24.4–27.0V breakdown voltage (VBR) at 1mA, clamps transients to ≤35.5V at 84.5A peak pulse current (IPP), and meets IEC-61000-4-2 ESD immunity (30kV air/30kV contact). It is used in industrial power supplies to safeguard 24V control inputs against lightning-induced surges.
For engineers reviewing the 3.0SMCJ22CA-13 datasheet, 3.0SMCJ22CA-13 pinout, 3.0SMCJ22CA-13 application, or 3.0SMCJ22CA-13 equivalent, this page delivers verified electrical parameters, SMC package mechanical data, clamping performance under 10/1000μs waveform, JEDEC-compliant thermal ratings, and direct alternatives with documented voltage and power differences.
Technical Context
This bi-directional TVS operates symmetrically across both polarities without cathode marking, enabling bidirectional surge suppression on AC-coupled or floating interfaces. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<5μA at VRWM), critical for low-power sensor nodes.
The device sustains 3000W peak pulse power per 10×1000μs waveform and derates linearly above +25°C ambient-maintaining ≥75% of rated power up to +85°C per Fig. 1. It supports 300A non-repetitive forward surge (IFSM) only in uni-directional variants; the CA suffix confirms bi-directional configuration with no polarity indicator.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - withstands 10/1000μs surges up to 84.5A without failure |
| Reverse Standoff Voltage | 22V - maximum continuous DC or RMS voltage before clamping initiates |
| Breakdown Voltage | 24.4–27.0V @ 1mA - precise VBR window ensures reliable turn-on margin above VRWM |
| Clamping Voltage | ≤35.5V @ 84.5A - limits downstream IC voltage stress during surge events |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - protects against human-handling discharge |
| Operating Temperature | −55°C to +150°C - qualified for under-hood automotive and industrial environments |

|---|---|
Use Scenario: 24V digital input channels in programmable logic controllers exposed to inductive kickback from solenoid loads. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed directly at connector entry point to shunt surge energy before reaching MCU GPIO or optocoupler input. Use Value: Limits transient voltage to ≤35.5V, protecting 3.3V/5V logic-level receivers while surviving repeated 1kV/500A surge tests per IEC 61000-4-5. |
Use Scenario: LIN bus transceiver power supply rail in door module electronics subjected to load dump and jump-start conditions. IC Role / Device Role / Timing Role: Secondary protection stage after primary 40V-rated TVS, absorbing residual fast-rising edges from alternator transients. Use Value: Clamps 10/1000μs surges to 35.5V within 1ns response time, preventing latch-up in LIN PHY ICs operating at 12V nominal. |
| Telecom Power Feeds | Renewable Energy Inverter Control |
Use Scenario: -48V DC power feed lines in remote radio units where lightning-induced common-mode surges exceed 2kV. IC Role / Device Role / Timing Role: Bidirectional clamping element in differential-mode protection network across VIN–GND and return path. Use Value: Symmetric 22V standoff enables identical protection on positive and negative rails without polarity concerns, simplifying layout. |
Use Scenario: Auxiliary 24V control supply in solar inverter gate driver boards exposed to ground potential rise during grid fault events. IC Role / Device Role / Timing Role: Final-stage TVS on isolated DC-DC converter output, guarding microcontroller reset and enable pins. Use Value: −55°C to +150°C operating range ensures reliability during desert daytime ambient extremes and inverter heat soak conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22CA | 2000W PPK, same VRWM/VBR/VC but lower IPP (62.0A vs. 84.5A) | Limited to lower-energy surges; unsuitable for IEC 61000-4-5 Level 3+ testing | Select when board space constraints require SMB package and surge threat level is ≤2kV |
| SMCJ22CA | Same 3000W rating and SMC package, but obsolete Diodes part number (replaced by 3.0SMCJ22CA-13) | Identical electrical and mechanical specs; legacy marking only | Prefer 3.0SMCJ22CA-13 for guaranteed availability and updated RoHS 3 compliance |
Compared with SMBJ22CA, the 3.0SMCJ22CA-13 delivers 35% higher surge current handling in the same SMC footprint; versus legacy SMCJ22CA, it adds halogen-free certification and JEDEC high-reliability validation without design change.

FAQ
What does the "CA" suffix indicate in 3.0SMCJ22CA-13?
The "CA" suffix denotes a bi-directional configuration: the device clamps voltage transients equally in both polarities and lacks a cathode band marking. This distinguishes it from "A"-suffixed uni-directional variants that feature a visible cathode band and conduct only in reverse bias.
Can 3.0SMCJ22CA-13 be used in place of a uni-directional TVS like 3.0SMCJ22A-13?
No-it cannot replace a uni-directional TVS in circuits requiring DC blocking or polarity-sensitive clamping. Bi-directional operation means it conducts on both positive and negative excursions, which may cause unintended current paths in DC-biased signal lines or power rails with defined polarity.
What is the maximum PCB pad size recommended for thermal performance?
Per Diodes' datasheet, optimal thermal performance requires mounting on 8.00 mm² copper land areas (0.013 mm thick). Larger pads improve heat dissipation but must comply with SMC outline dimensions (E = 7.75–8.13 mm, C = 2.75–3.18 mm) to avoid solder bridging or tombstoning.
Does this TVS require external series impedance for safe operation?
Yes-like all TVS diodes, it must be paired with appropriate series impedance (e.g., fuse, PTC, or resistor) upstream to limit let-through current during clamping. Without current limiting, sustained overvoltage can cause thermal runaway even within its 3000W peak rating.
