Product details
Overview
3.0SMCJ22A-13 from Diodes Incorporated is a unidirectional 3000W surface-mount transient voltage suppressor (TVS) diode with 22V reverse standoff voltage, 24.4V minimum breakdown voltage, and 35.5V maximum clamping voltage at 84.5A peak pulse current. It provides IEC-61000-4-2 ESD protection (30kV air/30kV contact), HBM 8kV, and is used in DC power rail surge suppression for industrial motor drives and telecom power supplies.
For engineers reviewing the 3.0SMCJ22A-13 datasheet, 3.0SMCJ22A-13 pinout, 3.0SMCJ22A-13 application, or 3.0SMCJ22A-13 equivalent, key selection criteria include clamping voltage margin relative to protected IC VMAX, peak pulse current capability under 10/1000μs waveform, thermal derating above +25°C ambient, and SMC package solderability per MIL-STD-202.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds VBR (24.4–27.0V), it avalanches into low-impedance conduction, limiting downstream voltage to ≤35.5V at 84.5A. Its glass-passivated die ensures stable breakdown characteristics and low leakage (<5μA at 22V).
Designed for single-pulse transients (e.g., lightning-induced surges, inductive switch-off), it supports non-repetitive 8.3ms half-sine surges up to 300A and 10×1000μs waveform clamping per REA standards. Thermal derating begins at +25°C, with full power rated only at TA ≤ +25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains 10×1000μs surge without failure under specified mounting conditions |
| Reverse Standoff Voltage (VRWM) | 22V - maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 24.4V min / 27.0V max @ 1.0mA - defines precise avalanche initiation threshold for clamping onset |
| Clamping Voltage (VC) | 35.5V max @ 84.5A - limits protected circuit voltage during worst-case 10×1000μs transient |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - withstands direct electrostatic discharge events |
| Operating Temperature | −55°C to +150°C - supports under-hood automotive and industrial environments |
Pinout & Package
Package: SMC (DO-214AB), molded plastic, UL 94V-0 rated, 0.21g weight. Cathode band denotes polarity on unidirectional variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient return path | Connected to ground or low-impedance reference; carries full surge current during clamping |
| Cathode | Protected line connection | Connected to line being protected (e.g., 24V rail); voltage referenced to anode during conduction |
Key Features
| Feature | Design Value |
|---|---|
| 3000W peak pulse rating | Enables robust protection against high-energy surges (e.g., ISO 7637-2 Pulse 1/2b in 24V systems) |
| Glass-passivated die | Ensures stable VBR tolerance and long-term reliability under thermal cycling |
| RoHS-compliant matte tin plating | Supports lead-free reflow soldering per JEDEC J-STD-020 Level 1 moisture sensitivity |
| Low clamping ratio (VC/VRWM = 1.61) | Minimizes overvoltage stress on downstream 24V-rated components such as PMICs and gate drivers |
Applications
| Industrial Motor Drives | Telecom Power Supplies |
|---|---|
Use Scenario: Protection of 24V DC input rails against inductive kickback from relay coils and H-bridge switching. IC Role / Device Role: Shunt clamping device placed between 24V rail and chassis ground. Use Value: Limits transient voltage to ≤35.5V, preventing damage to 36V-max input PMICs and microcontrollers. |
Use Scenario: Surge suppression on -48V DC distribution bus in base station power modules. IC Role / Device Role: Unidirectional TVS connected cathode-to-rail to clamp positive-going transients only. Use Value: Withstands 3000W pulses while maintaining <5μA leakage at −48V, avoiding standby power loss. |
| Automotive Body Control Modules | Industrial PLC I/O Terminals |
Use Scenario: Input protection for LIN bus transceivers powered from switched 12V supply. IC Role / Device Role: Standoff voltage matched to 12V system (VRWM = 22V allows margin for load dump overshoot). Use Value: Clamps ISO 16750-2 load dump spikes to <35.5V, preserving transceiver integrity without crowbar action. |
Use Scenario: Field-side protection on 24V digital input cards exposed to wiring-induced surges. IC Role / Device Role: Primary front-end protector mounted directly at terminal block entry point. Use Value: Handles repeated 10×1000μs transients up to 84.5A, enabling >100,000 surge cycles per IEC 61000-4-5 compliance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22A | 600W rating, same VRWM/VC, SMB package (smaller footprint, lower thermal mass) | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a | Select when board space is constrained and surge energy ≤600W suffices |
| 1.5SMCJ22A | 1500W rating, identical VRWM/VC, same SMC package but lower PPK | Half the peak power handling; requires parallel placement for 3000W duty | Choose when cost sensitivity outweighs single-device robustness and layout simplicity |
Compared with SMBJ22A and 1.5SMCJ22A, the 3.0SMCJ22A-13 delivers double the surge energy capacity in the same SMC footprint, eliminating need for paralleling and simplifying thermal design for high-reliability 24V systems.

FAQ
What is the maximum clamping voltage of the 3.0SMCJ22A-13 at its rated peak pulse current?
The maximum clamping voltage (VC) is 35.5V at 84.5A peak pulse current, measured under the standardized 10×1000μs waveform per REA specifications. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuits during surge events.
Is the 3.0SMCJ22A-13 suitable for bidirectional signal line protection?
No - the "A" suffix indicates unidirectional configuration with a cathode band. For bidirectional protection (e.g., AC lines or data buses), the "CA" variant (e.g., 3.0SMCJ22CA-13) must be used, which has symmetrical breakdown in both polarities and no polarity marking.
How does the SMC package affect thermal performance compared to SMA or SMB?
The SMC package offers larger copper pad area (8.00mm² recommended) and higher thermal mass than SMA/SMB, enabling better heat dissipation during repetitive surges. Its 0.21g mass and 94V-0 mold compound support sustained operation up to +150°C junction temperature under proper PCB layout.
Does this TVS diode require external series impedance for optimal protection?
Yes - a series current-limiting resistor or ferrite bead is typically placed between the protected IC and the TVS anode to reduce di/dt stress and prevent oscillation. The 3.0SMCJ22A-13's low dynamic impedance (≈0.14Ω derived from ΔV/ΔI) makes it effective only when paired with appropriate upstream impedance to shape the transient waveform.
