Product details
Overview
P6SMAJ54ADFQ-13 from Diodes Incorporated is an AEC-Q101 qualified, 600W surface-mount transient voltage suppressor (TVS) diode in the D-FLAT package, designed for automotive power line and signal line protection. It features a 54V reverse standoff voltage, 60.0–69.0V breakdown range at 1mA, 87.1V max clamping voltage at 6.9A peak pulse current, and is rated for -55°C to +150°C operation.
For engineers reviewing the P6SMAJ54ADFQ-13 datasheet, P6SMAJ54ADFQ-13 pinout, P6SMAJ54ADFQ-13 application, or P6SMAJ54ADFQ-13 equivalent, this device serves as a robust, RoHS-compliant, halogen-free TVS for ESD and surge suppression in automotive ECUs, infotainment power rails, and CAN/LIN bus interfaces where space-constrained, high-reliability transient protection is required.
Technical Context
This unidirectional TVS diode operates in avalanche breakdown mode to clamp transient overvoltages above its standoff threshold. Its glass-passivated junction ensures stable VBR and low leakage (<1µA @ 54V), while the D-FLAT package enables low-inductance mounting critical for fast 10/1000µs waveform response.
Thermal performance is optimized for PCB-mounted operation: RθJA = 92°C/W on a 0.4" × 0.5" 2oz copper pad, supporting sustained 1.0W average power dissipation. The cathode-band polarity marking and matte tin annealed terminals ensure reliable solderability per MIL-STD-202.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - Clamps 10/1000µs transients without failure under automotive load dump conditions. |
| Reverse Standoff Voltage (VRWM) | 54.0V - Maximum continuous DC or RMS voltage before significant leakage begins; sets operating margin for 48V systems. |
| Breakdown Voltage (VBR) | 60.0–69.0V @ 1mA - Tight tolerance ensures predictable turn-on across temperature and production lot. |
| Max Clamping Voltage (VC) | 87.1V @ 6.9A - Defines worst-case protected circuit voltage during surge; enables downstream IC survival with ≥15V headroom. |
| Peak Pulse Current (IPP) | 6.9A - Sustains standardized 10/1000µs surge events per IEC 61000-4-5 Level 4. |
| Operating Temperature | -55°C to +150°C - Fully qualified for under-hood automotive environments per AEC-Q101. |
| Package | D-FLAT (2.25–2.95mm × 3.95–4.60mm × 0.90–1.10mm) - Low-profile, board-space-efficient surface mount with defined thermal pad layout. |
Pinout & Package
Package: D-FLAT - Molded plastic case (UL 94V-0), cathode-banded polarity, matte tin annealed copper lead-frame, 0.035g weight. Optimized for minimal parasitic inductance and high thermal transfer via exposed terminal pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Anode of internal PN junction (cathode-marked terminal) | Connected to protected line; clamps to ground when transient exceeds VRWM; requires low-impedance ground return path. |
| 2 (Anode) | Cathode of internal PN junction (unmarked terminal) | Typically tied to system ground or low-impedance reference plane; forms clamping loop with cathode-connected line. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die construction | Ensures long-term VBR stability and <1µA leakage at rated VRWM, critical for battery-sensitive automotive modules. |
| AEC-Q101 qualification & IATF16949 manufacturing | Validates reliability for automotive safety-critical applications including body control modules and ADAS power supplies. |
| Halogen- and antimony-free "Green" design | Meets automotive OEM environmental requirements (<900ppm Br, <900ppm Cl, <1000ppm Sb); supports end-of-life recycling compliance. |
| Low-profile D-FLAT package | Reduces board area by >30% vs. SMA; enables placement near connectors or IC power pins for shortest possible transient path. |
| 64°C/W junction-to-terminal thermal resistance | Enables efficient heat transfer to PCB copper, supporting 1.0W steady-state dissipation without derating in compact layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ54A-Q | Same 54V VRWM, 600W rating, but non-automotive grade; not AEC-Q101 qualified or PPAP capable. | Limited to industrial/commercial use; lacks IATF16949 traceability and automotive change control. | Select only for cost-sensitive non-automotive designs where AEC-Q101 is not mandated. |
| 1.5SMC54A | Same electrical specs but in larger SMC (DO-214AB) package; 1.5W steady-state rating vs. 1.0W; RθJA = 115°C/W. | Requires ~2.5× more board area; less suitable for dense automotive PCBs; higher thermal resistance limits power handling. | Choose only if legacy SMC footprint compatibility is required or thermal mass demands exceed D-FLAT capability. |
Compared with SMAJ54A-Q and 1.5SMC54A, P6SMAJ54ADFQ-13 uniquely delivers AEC-Q101 assurance, D-FLAT space efficiency, and IATF16949 traceability-making it the sole choice for new automotive designs requiring PPAP submission and zero-defect reliability.

FAQ
What is the maximum clamping voltage of P6SMAJ54ADFQ-13 at its rated peak pulse current?
The maximum clamping voltage (VC) is 87.1V at 6.9A peak pulse current (IPP), measured using the standardized 10/1000µs waveform per IEC 61000-4-5. This value defines the upper voltage limit imposed on protected circuits during surge events and is guaranteed across the full operating temperature range (-55°C to +150°C).
Is P6SMAJ54ADFQ-13 suitable for bidirectional transient suppression?
No. P6SMAJ54ADFQ-13 is a unidirectional TVS diode, intended for DC or single-polarity signal line protection. Its schematic symbol and cathode-band marking indicate polarity-sensitive operation; applying reverse bias beyond its rated standoff voltage will cause conduction. For AC or bidirectional lines (e.g., RS-485), a bidirectional variant such as P6SMBJ54CA-13 must be used.
How does the D-FLAT package improve thermal performance compared to standard SMA packages?
The D-FLAT package features a flat, low-profile structure with extended terminal pads that maximize copper contact area on the PCB. With RθJA = 92°C/W on a 0.4" × 0.5" 2oz copper pad-versus ~115°C/W for SMA-it achieves up to 20% lower junction temperature rise under identical 1.0W steady-state power, enabling higher reliability in thermally constrained automotive layouts.
Does P6SMAJ54ADFQ-13 require derating for operation above +25°C ambient?
Yes. While the device operates from -55°C to +150°C, its peak pulse power rating of 600W is specified at TA = +25°C. Above this temperature, PPK must be linearly derated per the datasheet's derating curve (Fig. 3), reaching ~400W at +85°C ambient. Steady-state power dissipation remains fixed at 1.0W regardless of ambient, limited by package thermal resistance.
