Product details
Overview
3.0SMCJ150AQ-13 from Diodes Incorporated is a unidirectional 3000W surface-mount transient voltage suppressor (TVS) diode with 150V reverse standoff voltage, 167–184.6V breakdown range at 1mA, and 243V max clamping voltage at 12.3A peak pulse current. It delivers IEC-61000-4-2 ESD protection (30kV air/30kV contact), operates from –55°C to +150°C, and is used in automotive power rail surge suppression.
For engineers reviewing the 3.0SMCJ150AQ-13 datasheet, 3.0SMCJ150AQ-13 pinout, 3.0SMCJ150AQ-13 application, or 3.0SMCJ150AQ-13 equivalent, key selection criteria include clamping voltage margin vs. system rail, peak pulse current capability under 10/1000μs waveform, unidirectional polarity marking, SMC package thermal derating above +25°C, and AEC-Q101 qualification status for automotive use.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast response (<1ps) to transient overvoltages and low dynamic impedance during clamping. Its unidirectional configuration provides forward conduction path only when cathode is negative relative to anode, enabling precise placement on DC rails where reverse polarity must be blocked.
The device meets JEDEC high-reliability standards and is rated for 3000W peak pulse power per 10×1000μs waveform, with thermal derating beginning at +25°C ambient (per Fig. 1). It supports 300A non-repetitive surge current under 8.3ms half-sine wave, but only in unidirectional mode as specified in Notes 6–8.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains single 10×1000μs transients without failure; defines maximum energy absorption capacity. |
| Reverse Standoff Voltage (VRWM) | 150V - maximum continuous DC or RMS voltage before significant leakage; sets minimum operating rail margin. |
| Breakdown Voltage (VBR) | 167–184.6V @ 1mA - guaranteed conduction onset window; ensures reliable triggering above system nominal voltage. |
| Max Clamping Voltage (VC) | 243V @ 12.3A - upper voltage limit during surge; determines protected circuit's maximum stress level. |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - qualifies for direct interface protection in harsh environments. |
| Operating Temperature | –55°C to +150°C - supports under-hood automotive deployment and industrial power supply locations. |
| Package | SMC (DO-214AB) - surface-mount outline with 6.9mm × 4.4mm pad layout; enables high-current PCB routing and thermal dissipation. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic body with matte tin-plated leads, UL 94V-0 flammability rating, moisture sensitivity level 1. Cathode band denotes polarity for unidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Transient current sink terminal | Connected to ground or low-impedance return path; carries full surge current during clamping event. |
| Cathode (K) | Protected line connection | Connected to positive rail (e.g., 12V/24V/48V); marked by visible band; blocks reverse current until VBR exceeded. |
Key Features
| Feature | Design Value |
|---|---|
| 3000W peak pulse power | Enables robust protection against ISO 7637-2 Pulse 1/2a/5a surges in 12V/24V automotive systems without derating. |
| Glass-passivated die construction | Ensures stable VBR and low leakage across temperature and lifetime; eliminates passivation-related field failures. |
| AEC-Q101 qualified | Validated for automotive applications requiring change control, PPAP, and IATF 16949 manufacturing compliance. |
| Lead-free & halogen-free "Green" | Meets RoHS 3 (2015/863/EU) and Diodes' <900ppm Br/Cl, <1000ppm Sb definition; supports eco-design requirements. |
| Low clamping ratio (VC/VBR ≈ 1.46) | Minimizes overvoltage exposure to downstream ICs; critical for protecting 150V-rated MOSFETs or gate drivers. |
Applications
| Automotive Body Control Module (BCM) | Industrial 48V DC Power Distribution |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A | 2000W PPK, same VRWM (150V), higher VC (246V), SMB package (smaller footprint, lower thermal mass) | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a in automotive. | Select when board space is constrained and peak surge energy ≤2000W; verify thermal derating at >+85°C ambient. |
| SMCJ150A | Identical electrical specs and SMC package, but lacks Q-suffix AEC-Q101 qualification and automotive change control. | Not approved for production automotive programs requiring PPAP or IATF 16949 traceability. | Use only in industrial or consumer designs where automotive-grade reliability and documentation are not required. |
Compared with SMBJ150A, 3.0SMCJ150AQ-13 delivers 50% higher surge energy handling and superior thermal stability; versus SMCJ150A, it adds documented AEC-Q101 qualification, lot-level PPAP support, and controlled manufacturing change processes essential for Tier 1 automotive supply chains.

FAQ
What does the 'Q' suffix signify in 3.0SMCJ150AQ-13?
The 'Q' suffix indicates full AEC-Q101 qualification, including stress testing per JESD22-A108, high-temperature operating life (HTOL), and temperature cycling. It confirms manufacturing in IATF 16949-certified facilities, PPAP readiness, and controlled change management-required for automotive production programs.
Can 3.0SMCJ150AQ-13 be used in bidirectional configurations?
No. This part is unidirectional only, as confirmed by its cathode band marking and specification table entry ('Uni' column). Bidirectional operation requires a part marked '(C)' in the ordering code (e.g., 3.0SMCJ150CA-13), which has symmetrical breakdown in both polarities and no polarity indicator.
How does thermal derating affect 3.0SMCJ150AQ-13's 3000W rating?
The 3000W rating applies only at TA = +25°C. Per Figure 1 in DS30818 Rev. 18, power capability drops linearly to ~60% at +100°C ambient. Designers must size PCB copper area per Diodes' recommended SMC pad layout (6.9mm × 4.4mm) and verify junction temperature remains ≤+150°C under worst-case surge repetition.
Is 3.0SMCJ150AQ-13 compatible with lead-free reflow profiles?
Yes. It features matte tin-plated leads compliant with IPC/JEDEC J-STD-020 moisture sensitivity level 1 and withstands peak reflow temperatures up to +260°C. The UL 94V-0 mold compound is rated for standard lead-free soldering cycles without delamination or parametric shift.
