Product details
Overview
P6SMAJ22ADF-13 from Diodes Incorporated is a 600W surface-mount transient voltage suppressor (TVS) diode in the D-FLAT package, designed for unidirectional overvoltage protection of DC power rails and signal lines. It features a 22V reverse standoff voltage (VRWM), 24.4–28.0V breakdown range (VBR), 35.5V max clamping voltage (VC) at 16.9A peak pulse current (IPP), and fast response to 10/1000µs transients - deployed in industrial power supplies and automotive body control modules.
For engineers reviewing the P6SMAJ22ADF-13 datasheet, P6SMAJ22ADF-13 pinout, P6SMAJ22ADF-13 application, or P6SMAJ22ADF-13 equivalent, this page delivers verified electrical parameters, thermal resistance values, polarity marking details, clamping performance under standardized surge waveforms, and direct alternatives with documented voltage and power differences.
Technical Context
This unidirectional TVS diode operates as a shunt-clamping device that remains high-impedance below VRWM = 22V and rapidly transitions to low-impedance conduction above VBR (min 24.4V) to limit transient energy. Its glass-passivated die construction ensures stable leakage (<1.0µA at VRWM) and repeatable breakdown behavior across temperature.
Thermal performance is defined by RθJA = 92°C/W on a 0.4" × 0.5" FR-4 board, enabling reliable 1.5W steady-state dissipation at TL = +75°C. The 10×1000µs pulse waveform compliance (per REA) confirms suitability for IEC 61000-4-5 Level 3/4 surge immunity designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - sustains single 10×1000µs surges without failure, meeting IEC 61000-4-5 Class 3 requirements. |
| Reverse Standoff Voltage | 22V - maximum continuous DC operating voltage before significant leakage; sets system rail margin. |
| Breakdown Voltage Range | 24.4–28.0V - guaranteed conduction onset window at 1.0mA test current, ensuring predictable turn-on timing. |
| Max Clamping Voltage | 35.5V at 16.9A IPP - limits downstream IC voltage stress during worst-case surge events. |
| Peak Pulse Current | 16.9A - maximum non-repetitive surge current handled at rated clamping voltage. |
| Reverse Leakage | ≤1.0µA at 22V - negligible standby power loss and minimal impact on high-impedance sensing circuits. |
| Package | D-FLAT - ultra-low-profile (1.1mm max height), 2-pin SMT footprint saving board space vs. SMA/SMB. |
Pinout & Package
The P6SMAJ22ADF-13 uses the D-FLAT surface-mount package: 2-terminal, cathode-band marked, molded plastic case (UL 94V-0), 0.035g weight, with matte tin–annealed copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Anode-side connection point for unidirectional clamping | Connected to protected line; conducts when transient exceeds VBR, shunting current to ground. |
| 2 (Anode) | Reference/ground return path | Tied to system ground or low-impedance return plane; completes clamping current path during surge. |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse rating | Enables robust protection against lightning-induced surges and inductive switching spikes in 24V industrial systems. |
| Glass-passivated die | Ensures long-term parameter stability and reduced parameter drift under thermal cycling and humidity exposure. |
| D-FLAT low-profile package | Reduces PCB height to ≤1.1mm while maintaining thermal performance comparable to SMA packages. |
| RoHS-compliant & halogen-free | Meets IPC-1752A material declaration requirements and EU Directive 2011/65/EU without exemptions. |
| Cathode band polarity indicator | Eliminates orientation errors during automated placement; visible under optical inspection and AOI systems. |
Applications
| Industrial PLC I/O Protection | Automotive Body Control Module |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A-Q | Same VRWM (22V) and VC (35.5V), but SMA package (higher profile, RθJA = 115°C/W). | Less suitable for ultra-thin designs; requires larger pad layout and higher thermal relief. | Select when legacy SMA footprint compatibility is required and board height >2.0mm is acceptable. |
| 1.5SMC22A | Higher PPK = 1500W, same VRWM, but larger SMC package and higher clamping (38.9V @ 38.9A). | Better for high-energy surges but introduces higher voltage stress on protected ICs. | Choose only if system-level testing confirms 38.9V clamping is within downstream IC absolute maximum ratings. |
Compared with SMAJ22A-Q and 1.5SMC22A, P6SMAJ22ADF-13 offers optimal balance of low-profile packaging, industry-standard 600W surge handling, and tight 35.5V clamping - critical for space-constrained 24V industrial and automotive electronics where both mechanical fit and voltage margin are design-critical.

FAQ
What is the polarity configuration of P6SMAJ22ADF-13?
P6SMAJ22ADF-13 is a unidirectional TVS diode with cathode-band marking on Terminal 1. It conducts only when the cathode is positive relative to the anode, making it suitable for DC rail protection where polarity is fixed. This differs from bidirectional variants that protect AC or floating signals.
How does the D-FLAT package affect thermal performance compared to SMA?
The D-FLAT package achieves RθJA = 92°C/W on a 0.4" × 0.5" FR-4 board - 23°C/W lower than the SMA variant's 115°C/W - due to optimized copper pad geometry and shorter thermal path. This allows higher sustained power dissipation in thermally constrained layouts without derating.
Can P6SMAJ22ADF-13 be used in automotive infotainment systems?
Yes - its -55°C to +150°C operating range, AEC-Q200 alignment (via construction and qualification methodology), and ISO 7637-2 Pulse 1/2b compliance make it suitable for infotainment power rails and USB/UART interface protection, provided clamping voltage (35.5V) stays within downstream IC absolute maximum ratings.
What is the meaning of the "-13" suffix in the part number?
The "-13" suffix denotes tape-and-reel packaging: 10,000 units per reel, compatible with standard SMT pick-and-place equipment. It specifies packaging format only - electrical, thermal, and mechanical specifications are identical to the base P6SMAJ22ADF designation.
