Product details
Overview
P6SMAJ16ADFQ-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-grade overvoltage protection. It features a 16V reverse standoff voltage, 17.8–20.5V breakdown range at 1mA, 26.0V max clamping voltage at 23.1A peak pulse current, and is optimized for ESD and surge suppression in power rails and signal lines.
For engineers reviewing the P6SMAJ16ADFQ-13 datasheet, P6SMAJ16ADFQ-13 pinout, P6SMAJ16ADFQ-13 application, or P6SMAJ16ADFQ-13 equivalent, this device is selected for robust, low-capacitance (<100pF), fast-response (sub-nanosecond) transient suppression in 12V/24V automotive subsystems including infotainment, body control modules, and sensor interfaces.
Technical Context
This unidirectional TVS diode operates as a clamping device that remains non-conductive below its 16V VRWM threshold and rapidly transitions to low-impedance conduction above its 17.8V minimum breakdown voltage. Its glass-passivated junction ensures stable leakage (<1µA at VRWM) and repeatable clamping performance under repetitive transients.
The device delivers 600W peak pulse power handling per the 10/1000µs waveform, with thermal resistance of 64°C/W (junction-to-terminal) on standard FR-4 PCBs. Its D-FLAT package enables compact layout while maintaining high surge current capability (23.1A IPP) and low forward voltage (3.5V @ 35A).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - Sustains single 10/1000µs surges up to 600W without failure |
| Reverse Standoff Voltage | 16V - Maximum continuous DC or RMS voltage before significant leakage |
| Breakdown Voltage Range | 17.8–20.5V @ 1mA - Confirmed turn-on window ensuring reliable clamping onset |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-Q | Same 16V VRWM and 26V VC, but not AEC-Q101 qualified; JEDEC-standard SMA package (higher profile, 2.5mm height) | Limited to industrial/commercial use; unsuitable for PPAP-controlled automotive production | Select only for cost-sensitive non-automotive designs where qualification and footprint are secondary |
| TPSMAJ16A | Identical electrical specs and AEC-Q101 rating, but uses larger SMA package (4.5mm × 2.7mm vs. D-FLAT's 4.6mm × 2.8mm); slightly higher RθJA (115°C/W) | Acceptable for same automotive functions but requires more PCB area and has lower thermal margin on dense boards | Choose when legacy SMA footprint compatibility is required, or when D-FLAT placement equipment is unavailable |
Compared with SMAJ16A-Q and TPSMAJ16A, P6SMAJ16ADFQ-13 uniquely combines AEC-Q101 compliance, D-FLAT low-profile packaging, and validated IATF16949 manufacturing-enabling direct integration into space-constrained, safety-critical automotive ECUs without redesign or qualification overhead.

FAQ
What is the maximum clamping voltage of P6SMAJ16ADFQ-13 at its rated peak pulse current?
The maximum clamping voltage (VC) is 26.0V at a peak pulse current (IPP) of 23.1A, measured using the standardized 10/1000µs double-exponential waveform per IEC 61000-4-5. This value is guaranteed across temperature and lifetime, enabling precise overvoltage margining in 12V automotive systems.
Is P6SMAJ16ADFQ-13 suitable for bidirectional transient protection?
No-it is a unidirectional TVS diode, intended for DC or polarity-defined circuits. Its schematic shows cathode/anode polarity, and it conducts only when the cathode is driven positive relative to the anode. For AC or bidirectional signal lines, a dedicated bidirectional variant (e.g., P6SMBJ16ADFQ-13) must be used.
How does the D-FLAT package improve thermal performance compared to standard SMA?
The D-FLAT package reduces junction-to-terminal thermal resistance to 64°C/W (vs. ~100°C/W for SMA), due to its wider copper pad contact area and shorter internal thermal path. When mounted on a 1"×1", 2oz FR-4 pad, it sustains higher average power dissipation (1.0W) and improves reliability under repeated surge stress.
Does P6SMAJ16ADFQ-13 require derating at elevated ambient temperatures?
Yes-its peak pulse power rating is derated linearly above +25°C ambient, with full 600W only guaranteed at TA = +25°C. At +85°C, the derated PPK is approximately 420W. The datasheet provides a derating curve (Figure 3), and design margins must account for both ambient temperature and PCB thermal mass.
