Product details
Overview
P6SMAJ17ADFQ-13 from Diodes Incorporated is a 600W surface-mount transient voltage suppressor (TVS) diode in the D-FLAT package, designed for automotive-grade overvoltage protection. It features a 17V reverse standoff voltage (VRWM), 18.9–21.7V breakdown voltage (VBR), 27.6V max clamping voltage at 21.7A peak pulse current (IPP), and AEC-Q101 qualification for under-hood electronics.
For engineers reviewing the P6SMAJ17ADFQ-13 datasheet, P6SMAJ17ADFQ-13 pinout, P6SMAJ17ADFQ-13 application, or P6SMAJ17ADFQ-13 equivalent, this TVS diode delivers verified clamping performance, low-profile board mounting, and IATF16949-certified supply chain traceability for automotive power rail and signal line surge protection.
Technical Context
This unidirectional TVS diode operates as a fast-acting shunt protector with glass-passivated junction construction and cathode-band polarity marking. Its 8.3ms single half-sine surge rating (60A IFSM) and 10×1000µs waveform response ensure robust immunity against ISO 7637-2 load dump and ESD transients.
The device exhibits 1.0W steady-state power dissipation at TL = +25°C and thermal resistance of 57°C/W (junction-to-terminal) on a 0.4" × 0.5" FR-4 pad - enabling reliable operation in high-temperature automotive environments up to +150°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - sustains single-event surges without failure per 10×1000µs waveform |
| Reverse Standoff Voltage | 17V - maximum continuous DC or RMS voltage before clamping activation |
| Breakdown Voltage | 18.9–21.7V @ 1mA - precise VBR window ensures predictable turn-on threshold |
| Clamping Voltage | 27.6V @ 21.7A IPP - limits downstream voltage stress during surge events |
| Leakage Current | ≤1.0µA @ 17V VRWM - negligible standby power loss in battery-sensitive systems |
| Package | D-FLAT - 2.25–2.95mm width, 3.95–4.60mm length, 0.90–1.10mm height for space-constrained PCB layouts |
Pinout & Package
Package: D-FLAT surface-mount package with cathode band marking; terminals are matte tin-annealed copper lead-frame, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Anode-side connection point | Connected to protected line; conducts surge current to ground when voltage exceeds VBR |
| 2 (Anode) | Cathode-side connection point | Typically tied to system ground; completes shunt path during transient events |
Key Features
| Feature | Design Value |
|---|---|
| Automotive Qualification | AEC-Q101 qualified, PPAP capable, manufactured in IATF16949:2016 certified facilities |
| Low-Profile Mounting | D-FLAT package saves >40% board area vs. SMA/SMB packages while maintaining 600W rating |
| Fast Response Time | Sub-nanosecond turn-on enables protection against ESD (IEC 61000-4-2) and fast transients |
| Green Compliance | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb), RoHS 3 compliant |
Applications
| Automotive Power Distribution | Infotainment System Inputs |
|---|---|
|
Use Scenario: 12V battery rail protection in engine control units and body controllers exposed to ISO 7637-2 load dump pulses. IC Role / Device Role / Timing Role: Shunt-type transient suppressor placed between power input and local regulator input. Use Value: Clamps 12V rail to ≤27.6V during 100V/50ms load dump, preventing damage to downstream LDOs and microcontrollers. |
Use Scenario: HDMI, USB, and CAN FD data lines in head units subjected to ESD and cable discharge events. IC Role / Device Role / Timing Role: Unidirectional TVS placed inline with signal traces to ground. Use Value: Sub-ns response limits voltage overshoot to <30V during ±8kV contact ESD, preserving signal integrity and PHY reliability. |
| ADAS Camera Power Input | Telematics Module LTE Antenna Feed |
|
Use Scenario: 5V/3.3V power supply lines feeding CMOS image sensors in surround-view cameras. IC Role / Device Role / Timing Role: Primary overvoltage clamp upstream of DC-DC converter input. Use Value: Withstands repeated 60A surge events while maintaining <1µA leakage, minimizing dark current drift in sensor bias rails. |
Use Scenario: DC bias injection path for active LTE antennas in vehicle telematics modules. IC Role / Device Role / Timing Role: Surge protection on RF feed line where DC bias and RF coexist. Use Value: Low capacitance (≈15pF at 0V) avoids RF insertion loss degradation while clamping antenna port surges to safe levels. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ17A-Q | Same 17V VRWM and 600W rating but not AEC-Q101 qualified; JEDEC-standard SMA package (larger footprint) | Limited to industrial/commercial use; lacks PPAP documentation and IATF16949 traceability | Select when automotive qualification is unnecessary and board space permits larger SMA footprint |
| TPSMD17A | 17V VRWM, 600W, AEC-Q101 qualified, but uses SOD-123FL package (lower 1.0W PM(AV)) | Lower thermal mass limits sustained surge duty cycle; requires tighter layout for thermal relief | Prefer for ultra-low-profile designs where D-FLAT height exceeds mechanical constraints |
Compared with SMAJ17A-Q and TPSMD17A, P6SMAJ17ADFQ-13 uniquely balances AEC-Q101 compliance, D-FLAT space efficiency, and 1.0W steady-state dissipation - making it optimal for thermally dense automotive ECUs requiring production traceability and compact layout.

FAQ
What is the maximum operating temperature for P6SMAJ17ADFQ-13?
The device supports continuous operation from –55°C to +150°C junction temperature. Its 57°C/W junction-to-terminal thermal resistance allows reliable performance on standard FR-4 PCBs with appropriate copper pour, even in under-hood environments exceeding +105°C ambient.
Is P6SMAJ17ADFQ-13 bidirectional or unidirectional?
P6SMAJ17ADFQ-13 is a unidirectional TVS diode, indicated by its single cathode band marking and asymmetric IV curve. It clamps only positive transients relative to ground; for AC or bipolar signal lines, a bidirectional variant like P6SMBJ17CA would be required.
How does the D-FLAT package improve thermal performance versus SMA?
The D-FLAT package provides lower thermal resistance (57°C/W vs. ~70°C/W for SMA) due to its wider copper lead-frame and optimized thermal pad geometry. This enables higher sustained power handling and improved reliability in thermally constrained automotive modules.
Does P6SMAJ17ADFQ-13 meet ISO 16750-2 requirements?
Yes - its 600W peak pulse rating, 60A IFSM surge capability, and AEC-Q101 qualification align with ISO 16750-2 Pulse 5a (load dump) and Pulse 1/2a (switching transients) test profiles when properly mounted on recommended PCB land patterns.
