Product details
Overview
3.0SMCJ11AQ-13 from Diodes Incorporated is a unidirectional 3000W surface-mount transient voltage suppressor (TVS) diode with 11V reverse standoff voltage, 12.2–13.5V breakdown range at 1mA, and 18.2V max clamping voltage at 164.8A peak pulse current. It provides IEC-61000-4-2 ESD protection (30kV air/30kV contact), HBM 8kV, and is qualified for automotive applications per AEC-Q101 in SMC package.
For engineers reviewing the 3.0SMCJ11AQ-13 datasheet, 3.0SMCJ11AQ-13 pinout, 3.0SMCJ11AQ-13 application, or 3.0SMCJ11AQ-13 equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD, surge current handling under 10/1000μs waveform, unidirectional polarity marking, and AEC-Q101 qualification status for automotive power rail protection.
Technical Context
This TVS operates as a silicon avalanche diode that remains high-impedance below VRWM (11V), then rapidly transitions to low-impedance conduction above VBR (12.2–13.5V) to clamp transients. Its glass-passivated die ensures stable breakdown and low leakage (<5μA at VRWM).
The device uses a single-junction unidirectional structure with cathode band marking, optimized for DC power line protection where reverse polarity is defined. It meets JEDEC reliability standards and supports IATF 16949 manufacturing traceability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains 10/1000μs surges up to 164.8A without failure |
| Reverse Standoff Voltage | 11V - maximum continuous DC or RMS voltage before significant leakage |
| Breakdown Voltage Range | 12.2–13.5V @ 1mA - defines reliable turn-on threshold for overvoltage clamping |
| Max Clamping Voltage | 18.2V @ 164.8A - limits downstream voltage during worst-case surge |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - protects against human-handling discharge events |
| Operating Temperature | −55°C to +150°C - supports under-hood automotive environments and industrial power supplies |
| AEC-Q101 Qualified | Yes - certified for automotive electronics requiring change control and PPAP capability |
Pinout & Package

| Cathode | High-side transient input terminal | Marked with band; connects to protected line (e.g., 12V battery rail); conducts surge current to ground |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Automotive Power Rail Protection | Industrial DC Power Input |
|---|---|
Use Scenario: 12V battery line in engine control unit (ECU) exposed to load dump and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamps positive-going surges above 11V to protect downstream LDOs and microcontrollers. Use Value: Limits clamped voltage to 18.2V, maintaining safe margin below 20V absolute maximum ratings of common automotive PMICs. |
Use Scenario: 24V DC input stage of programmable logic controller (PLC) module subject to inductive switching noise. IC Role / Device Role / Timing Role: Fast-response avalanche diode shunts 10/1000μs transients before they propagate into isolated DC-DC converters. Use Value: 3000W rating enables survival of repeated 150V/50A surges per IEC 61000-4-5 Level 4 testing. |
| Telecom Power Interface | Medical Equipment DC Supply |
Use Scenario: −48V telecom rectifier output feeding base station backplane with hot-swap insertion events. IC Role / Device Role / Timing Role: Bidirectional-capable series (though this part is unidirectional) used in complementary pairs; this part handles positive excursions on referenced rails. Use Value: 164.8A peak current capacity prevents thermal runaway during 10ms surge events typical in telecom power distribution. |
Use Scenario: 5V/3.3V auxiliary supply rail in portable ultrasound device subjected to ESD during cable connection. IC Role / Device Role / Timing Role: Primary board-level ESD clamp on power entry, placed before bulk capacitance. Use Value: 30kV contact ESD rating exceeds IEC 61000-4-2 requirements for Class B medical equipment. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A-13-F | Lower 400W rating; 18.2V clamping at only 22A IPP; SMA package (smaller thermal mass) | Not suitable for load dump; limited to low-energy ESD and signal-line protection | Select only for space-constrained non-automotive applications with sub-50A surge exposure |
| 1.5SMC11AQ | Same 3000W rating and 11V VRWM but legacy SMC package without Q-suffix AEC-Q101 certification | Lacks PPAP support and automotive change control; not approved for new automotive designs | Use only in legacy industrial programs where AEC-Q101 is not mandated |
Compared with SMAJ11A-13-F and 1.5SMC11AQ, the 3.0SMCJ11AQ-13 uniquely combines full AEC-Q101 qualification, 3000W surge capacity, and SMC thermal performance-making it the only option qualified for new automotive power rail designs requiring production traceability and load dump immunity.

FAQ
What does the 'Q' suffix in 3.0SMCJ11AQ-13 signify?
The 'Q' suffix indicates AEC-Q101 qualification, meaning the device has passed stress tests for temperature cycling, humidity, mechanical shock, and electrical reliability required for automotive electronics. It also confirms manufacturing in an IATF 16949-certified facility with full PPAP documentation support and controlled change management.
Is 3.0SMCJ11AQ-13 unidirectional or bidirectional?
It is unidirectional, as confirmed by its cathode band marking and electrical specifications (e.g., reverse leakage measured only at VRWM). The 'A' in the part number denotes unidirectional configuration; bidirectional variants use 'CA' (e.g., 3.0SMCJ11CA-13) and lack polarity marking.
How does its 18.2V clamping voltage impact system design?
The 18.2V clamping voltage at 164.8A sets the upper voltage limit seen by downstream components during surge events. Designers must ensure all connected ICs have absolute maximum ratings exceeding 18.2V, and verify that bulk capacitance and upstream fusing allow the TVS to activate before damage occurs.
Can it replace older 1.5SMCJ11A parts in existing designs?
No direct drop-in replacement: while both are SMC-packaged 11V unidirectional TVS diodes, the 3.0SMCJ11AQ-13 has higher surge current capability (164.8A vs. ~100A), tighter VBR tolerance, and AEC-Q101 qualification. Layout and thermal design must be revalidated due to increased energy dissipation.
