Product details
Overview
P6SMAJ15ADF-13 from Diodes Incorporated is a 600W surface-mount transient voltage suppressor (TVS) diode in the D-FLAT package, designed for unidirectional overvoltage protection on DC power rails and signal lines. It features a 15V reverse standoff voltage (VRWM), 16.7–19.2V breakdown voltage (VBR), 24.4V clamping voltage (VC) at 24A peak pulse current, and fast response time for ESD and surge suppression in industrial and automotive electronics.
For engineers reviewing the P6SMAJ15ADF-13 datasheet, P6SMAJ15ADF-13 pinout, P6SMAJ15ADF-13 application, or P6SMAJ15ADF-13 equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD, thermal resistance under PCB layout constraints, IEC 61000-4-5 surge compliance, and D-FLAT footprint compatibility with high-density routing.
Technical Context
This unidirectional TVS diode operates as a shunt-clamping device that remains high-impedance below VRWM = 15V and rapidly transitions to low-impedance conduction above VBR (min 16.7V) to limit transient energy. Its glass-passivated die construction ensures stable leakage (<1µA at VRWM) and repeatable breakdown behavior across temperature.
The device delivers 600W peak pulse power (10/1000µs waveform) with a clamping ratio VC/VBR of ~1.45, enabling robust protection against 8/20µs surges up to 24A while maintaining safe voltage margins for 16–18V-rated downstream circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - Sustains single 10/1000µs transients without failure under defined thermal conditions |
| Reverse Standoff Voltage | 15V - Maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage | 16.7–19.2V @ 1mA - Confirmed avalanche onset range ensuring reliable triggering margin |
| Clamping Voltage | 24.4V @ 24A - Maximum voltage seen by protected circuit during worst-case 10/1000µs surge |
| Package | D-FLAT - Low-profile (1.1mm max height), 2-pin surface-mount package with cathode band polarity |
| Thermal Resistance | 92°C/W (Junction-to-Ambient) - Based on 0.4" × 0.5" 2oz copper pad; critical for power derating above +25°C |
| Leakage Current | ≤1.0µA @ 15V - Ensures minimal standby power loss and no interference with high-impedance sensing nodes |
Pinout & Package
Package: D-FLAT - Molded plastic case (UL 94V-0), 0.035g weight, matte tin–annealed copper leadframe, cathode band marking. Dimensions: 4.65mm × 2.80mm × 1.10mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Anode of internal PN junction | Connected to protected line (e.g., VBUS); conducts when transient exceeds VBR |
| 2 (Anode) | Cathode of internal PN junction | Connected to ground reference; establishes shunt path for surge current to GND |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die | Ensures stable VBR tolerance and long-term reliability under humidity and thermal cycling |
| Low-profile D-FLAT package | Reduces board space by >30% vs. SMA; enables placement near connectors or I/O ports |
| 600W peak pulse rating | Supports IEC 61000-4-5 Level 4 (4kV line-earth, 2kV line-line) compliance with margin |
| RoHS & Halogen-free | Meets EU RoHS 2 and green manufacturing requirements (<900ppm Br/Cl, <1000ppm Sb) |
Applications
| Industrial PLC I/O Protection | Automotive Body Control Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A | Same VRWM (15V), higher VC = 24.4V, but SMB package (larger footprint, 2.6mm height) | Less suitable for ultra-thin designs; better thermal dissipation on large pads | Select when board height >1.1mm is acceptable and higher steady-state power handling is needed |
| 1.5SMC15A | Same electrical specs, but SMC package (7.1mm × 6.2mm); PM(AV) = 1.5W vs. D-FLAT's 1.5W | Requires significantly more PCB area; used where legacy footprint compatibility is required | Choose only if redesigning to D-FLAT is not feasible and existing SMC land pattern must be reused |
Compared with SMBJ15A and 1.5SMC15A, P6SMAJ15ADF-13 offers identical clamping performance in a 40% smaller footprint and 58% lower profile-critical for space-constrained automotive and portable medical modules where Z-height and routing density are limiting factors.

FAQ
What is the maximum operating temperature for P6SMAJ15ADF-13?
The device supports continuous operation from –55°C to +150°C junction temperature. Derating begins above +25°C ambient per Figure 1: at +85°C ambient, peak pulse power drops to ~420W (70% of 600W) due to thermal resistance limitations in standard FR-4 layouts.
Does P6SMAJ15ADF-13 meet IEC 61000-4-2 and IEC 61000-4-5 standards?
Yes-its 24.4V clamping voltage at 24A and sub-nanosecond response enable compliance with IEC 61000-4-2 Level 4 (±15kV air, ±8kV contact) and IEC 61000-4-5 Level 4 (4kV line-earth) when implemented with proper PCB layout (short traces, low-inductance ground return).
Can P6SMAJ15ADF-13 be used in bidirectional configurations?
No-it is a unidirectional TVS diode with cathode-anode polarity. For bidirectional protection (e.g., AC lines or differential signals), use the complementary P6SMAJ15CA-13 variant, which contains two back-to-back diodes in one D-FLAT package.
What is the typical capacitance of P6SMAJ15ADF-13 at 0V bias?
Capacitance is not specified in the DS38930 datasheet for this series. Diodes Incorporated does not publish CT values for P6SMAJ devices; for low-capacitance signal-line protection, consider the DFN-based D1213A series or SMAJ variants with documented <100pF characteristics.
