Product details
Overview
P6SMAJ6.5ADF-13 from Diodes Incorporated is a 600W surface-mount transient voltage suppressor (TVS) diode designed for unidirectional overvoltage protection in DC power lines and signal paths. It features a reverse standoff voltage of 6.5V, breakdown voltage range of 7.22–8.30V at 10mA test current, clamping voltage of 11.2V at 53.6A peak pulse current, and D-FLAT package for space-constrained PCB layouts.
For engineers reviewing the P6SMAJ6.5ADF-13 datasheet, P6SMAJ6.5ADF-13 pinout, P6SMAJ6.5ADF-13 application, or P6SMAJ6.5ADF-13 equivalent, key selection criteria include clamping performance under 10/1000µs surge, low leakage (<500µA at VRWM), thermal resistance (RθJA = 92°C/W on 0.4"×0.5" pad), and RoHS-compliant green construction.
Technical Context
This unidirectional TVS diode operates as a shunt-clamping device, conducting when reverse voltage exceeds its breakdown threshold to divert surge energy away from protected circuitry. Its glass-passivated die ensures stable VBR tolerance and long-term reliability under repetitive transients.
Designed for single-pulse 10×1000µs waveform compliance per REA standards, it delivers 600W peak pulse power with fast response time (<1.0ps), low forward voltage (3.5V at 35A), and polarity-indicated cathode band for correct PCB orientation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - sustains single 10×1000µs surges without failure |
| Reverse Standoff Voltage | 6.5V - maximum continuous DC operating voltage before clamping initiates |
| Breakdown Voltage Range | 7.22–8.30V @ 10mA - defines precise conduction onset window for predictable protection |
| Clamping Voltage | 11.2V @ 53.6A - limits downstream voltage stress during worst-case surge |
| Max Reverse Leakage | 500µA @ 6.5V - ensures minimal standby power loss and signal integrity |
| Thermal Resistance (J-A) | 92°C/W - measured on 0.4"×0.5", 2oz FR-4 pad; enables thermal-aware layout |
| Package | D-FLAT - 4.65mm × 2.80mm footprint with 0.9–1.1mm height; saves board area vs. SMA |
Pinout & Package
The P6SMAJ6.5ADF-13 uses a 2-terminal D-FLAT surface-mount package with cathode indicated by a band on Terminal 1. The package has no internal leads; terminals are formed from a copper leadframe with matte tin annealed finish, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Banded) | Cathode | Connected to protected line's higher potential side; conducts when reverse voltage exceeds VBR |
| 2 | Anode | Connected to ground or lower potential reference; completes clamping path during surge |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Ensures consistent VBR stability and long-term surge endurance across temperature and life cycles |
| Low profile D-FLAT package | Reduces PCB footprint by ~30% vs. standard SMA while maintaining 600W rating |
| Lead-free & halogen-free | Meets RoHS 2 and JEDEC J-STD-020 Level 1 moisture sensitivity; supports green manufacturing |
| Fast response time | Sub-nanosecond turn-on protects sensitive ICs before transient energy couples into traces |
Applications
| USB Power Input Protection | Automotive Body Control Module |
|---|---|
Use Scenario: Protects 5V USB VBUS line from ESD and load dump-induced spikes in portable docking stations. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between VBUS and GND, clamping transients before they reach USB controller or PMIC. Use Value: Clamps to 11.2V at 53.6A, limiting stress on 5.5V-rated USB PHYs while surviving IEC 61000-4-2 ±15kV contact discharge. | Use Scenario: Shields LIN bus transceivers and microcontroller I/O from battery line transients during ignition or alternator load dump. IC Role / Device Role / Timing Role: Mounted at module input, clamping 12V rail surges to safe levels before reaching 5V LDOs and MCU pins. Use Value: Withstands 60A surge per ISO 7637-2 Pulse 1/2a and maintains <500µA leakage to avoid battery drain in sleep mode. |
| Industrial Sensor Interface | POS Terminal Power Rail |
Use Scenario: Safeguards 24V analog sensor inputs (e.g., 4–20mA loop receivers) against field-wiring induced surges. IC Role / Device Role / Timing Role: Placed at connector entry point, acting as first-line defense against induced lightning or inductive kickback. Use Value: 600W rating handles 10×1000µs surges up to 53.6A; 92°C/W RθJA allows reliable operation on compact sensor PCBs. | Use Scenario: Secures 12V main power rail in retail point-of-sale terminals exposed to AC adapter transients and hot-plug events. IC Role / Device Role / Timing Role: Parallel-connected TVS on primary DC input, clamping voltage excursions before bulk capacitors and DC-DC converters. Use Value: Low 11.2V clamping prevents overvoltage shutdown of 12V-input buck regulators; D-FLAT package fits tight enclosure layouts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5A | Same 6.5V VRWM and 11.2V VC, but SMB package (larger footprint, RθJA ≈ 115°C/W) | Higher thermal mass suits higher ambient temp environments; less board-space efficient | Select when thermal margin > electrical margin, or legacy SMB footprints exist |
| 1.5SMC6.8A | Higher 6.8V VRWM, 11.5V VC, 600W rating, but SMC package (7.1mm × 6.2mm) | Lower leakage (10µA) but larger size; suited for high-reliability industrial power supplies | Choose when tighter VRWM tolerance (±5%) and lower IR are critical, and space permits |
Compared with SMBJ6.5A and 1.5SMC6.8A, P6SMAJ6.5ADF-13 offers superior board-area efficiency (D-FLAT footprint), optimized thermal performance on small pads (92°C/W), and identical clamping behavior-making it ideal for space-constrained, thermally managed designs where layout density is prioritized.

FAQ
What is the maximum peak pulse current the P6SMAJ6.5ADF-13 can handle?
The P6SMAJ6.5ADF-13 is rated for a maximum peak pulse current (IPP) of 53.6A under the standardized 10×1000µs waveform. This value is derived directly from its 600W peak pulse power rating and 11.2V clamping voltage (IPP = PPK / VC). It is validated per REA-defined test conditions and assumes proper PCB thermal design per the datasheet's 0.4"×0.5" copper pad specification.
Does this TVS diode support bidirectional surge protection?
No, the P6SMAJ6.5ADF-13 is a unidirectional TVS diode, configured for protection of positive DC rails only. Its schematic symbol and marking (cathode band on Terminal 1) confirm single-polarity operation. For bidirectional applications such as AC lines or data buses, a separate bidirectional variant like P6SMBJ6.5CA or equivalent must be selected.
What is the significance of the "-13" suffix in the part number?
Per Diodes Incorporated's ordering information, the "-13" suffix indicates tape-and-reel packaging with 10,000 units per reel. This format is optimized for automated SMT assembly and ensures consistent feeding, orientation, and moisture barrier compliance (MSL Level 1 per J-STD-020), eliminating manual handling and humidity-related solder defects.
How does the D-FLAT package improve thermal performance compared to SMA?
The D-FLAT package achieves lower thermal resistance (RθJA = 92°C/W vs. ~115°C/W for SMA) due to its shorter thermal path and optimized copper pad layout (0.2"×0.25"). Its flat, low-profile structure enhances heat spreading into the PCB, enabling higher sustained power dissipation in compact layouts-critical for dense power rail protection near connectors or ICs.
