Product details
Overview
P6SMAJ13ADF-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 interfaces. It features a reverse standoff voltage of 13 V, breakdown voltage range of 14.4–16.5 V at 1.0 mA test current, clamping voltage of 21.5 V at 27.9 A peak pulse current, and D-FLAT package for space-constrained PCB layouts - deployed in industrial power supply input stages.
For engineers reviewing the P6SMAJ13ADF-13 datasheet, P6SMAJ13ADF-13 pinout, P6SMAJ13ADF-13 application, or P6SMAJ13ADF-13 equivalent, key selection criteria include clamping voltage margin vs. protected IC VMAX, peak pulse current capability under 10/1000 µs surge, thermal resistance to terminal (57–64 °C/W), and RoHS-compliant green packaging with matte tin annealed terminals.
Technical Context
This unidirectional TVS diode operates as a shunt-clamping device triggered by reverse-biased avalanche breakdown. Its glass-passivated die ensures stable VBR tolerance (±5% typical) and fast response time (<1 ns), enabling effective suppression of ESD (IEC 61000-4-2 Level 4) and lightning-induced surges (IEC 61000-4-5).
The D-FLAT package provides low thermal resistance (RθJT = 57–64 °C/W depending on pad layout) and supports high-power dissipation (600 W non-repetitive) while maintaining a footprint of only 2.25 × 3.95 mm. Polarity is marked by a cathode band; anode and cathode terminals are electrically isolated from heatsinking requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - sustains single 10/1000 µs transients without failure under defined board thermal conditions |
| Reverse Standoff Voltage (VRWM) | 13 V - maximum continuous DC or RMS voltage before leakage exceeds 1 µA |
| Breakdown Voltage (VBR) | 14.4–16.5 V @ 1.0 mA - defines reliable avalanche initiation threshold with tight tolerance |
| Clamping Voltage (VC) | 21.5 V @ 27.9 A - limits downstream voltage during surge, critical for protecting 24 V logic rails |
| Peak Pulse Current (IPP) | 27.9 A - maximum surge current supported under standard 10/1000 µs waveform |
| Thermal Resistance (RθJT) | 57–64 °C/W - determines junction temperature rise above terminal temperature based on PCB copper area |
Pinout & Package
Package: D-FLAT - low-profile surface-mount plastic case (2.25–2.95 mm length × 3.95–4.60 mm width × 0.90–1.10 mm height), UL 94V-0 rated, with cathode band polarity marking and matte tin annealed copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Surge current sink node | Connected to protected line; conducts avalanche current to ground during overvoltage events |
| 2 (Anode) | Reference/return path | Typically tied to system ground; completes shunt path for transient energy diversion |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse rating | Enables robust protection against IEC 61000-4-5 4 kV surge tests on 24 V industrial buses |
| Glass-passivated die construction | Ensures long-term VBR stability and reduced parameter drift over temperature and lifetime |
| D-FLAT low-profile package | Reduces board area by >40% vs. SMA; compatible with automated SMT placement and reflow |
| RoHS-compliant & halogen-free | Meets EU Directive 2011/65/EU and Diodes Inc.'s "Green" standard (<900 ppm Br/Cl, <1000 ppm Sb) |
Applications
| Industrial PLC I/O Protection | DC Power Input Stage |
|---|---|
|
Use Scenario: Protecting 24 V digital input modules from induced surges on factory floor wiring. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between field input and optocoupler input stage. Use Value: Clamps transients to ≤21.5 V, ensuring input logic remains within absolute maximum ratings of downstream buffer ICs. |
Use Scenario: Safeguarding switching regulator inputs against load dump and inductive kickback in 24 V systems. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main DC bus prior to buck converter input capacitor. Use Value: Absorbs up to 600 W surge energy without degradation, preserving upstream fuse and MOSFET reliability. |
| Automotive Body Control Module | RS-485 Communication Line |
|
Use Scenario: Protecting LIN bus transceivers and microcontroller GPIOs from battery line transients during cold crank. IC Role / Device Role / Timing Role: Secondary-level TVS on 12 V supply rail feeding BCM sub-circuits. Use Value: Fast <1 ns response prevents latch-up in 3.3 V MCU cores during ISO 7637-2 Pulse 1/2a events. |
Use Scenario: Shielding RS-485 transceiver data lines from ESD and cable discharge events in building automation networks. IC Role / Device Role / Timing Role: Bidirectional-capable protection (used unidirectionally with proper grounding) on A/B differential pairs. Use Value: Low clamping voltage (21.5 V) avoids false triggering of receiver common-mode range while passing 12 V signaling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-Q | Same 13 V VRWM, but lower PPK = 400 W; RθJA = 125 °C/W (higher thermal resistance) | Limited to lower-energy surges; less suitable for IEC 61000-4-5 Class 3+ environments | Select when cost sensitivity outweighs surge margin and board space allows larger thermal pads |
| 1.5SMC13A | Higher PPK = 1500 W, but larger SMC package (7.1 × 6.2 mm); VC = 21.2 V @ 71.4 A | Better surge handling but incompatible with dense layouts; requires ~3× PCB area | Choose when peak current exceeds 27.9 A or when legacy SMC footprint is fixed |
Compared with SMAJ13A-Q and 1.5SMC13A, P6SMAJ13ADF-13 delivers optimal balance of 600 W surge capacity, D-FLAT compactness, and 21.5 V clamping - making it preferred for space-constrained 24 V industrial controllers where thermal management via small copper pads is essential.

FAQ
What is the maximum operating temperature for P6SMAJ13ADF-13?
The device supports continuous operation from –55 °C to +150 °C junction temperature. At ambient temperatures above +75 °C, derating applies per Figure 1: peak pulse power decreases linearly to 50% at +125 °C ambient on standard FR-4 board layouts.
Is P6SMAJ13ADF-13 suitable for bidirectional surge protection?
No - it is a unidirectional TVS diode with cathode-anode polarity. For bidirectional protection, two devices must be used in series opposition, or a dedicated bidirectional part like P6SMBJ13CA should be selected instead.
How does the D-FLAT package affect soldering process compatibility?
The D-FLAT package uses matte tin annealed terminals compliant with MIL-STD-202 Method 208, supporting standard lead-free reflow profiles (peak 260 °C). Its low profile (≤1.1 mm height) eliminates tombstoning risk and enables fine-pitch placement down to 0.5 mm pitch.
What is the typical total capacitance at 0 V bias?
At VRWM = 13 V and f = 1 MHz, typical total capacitance is 200 pF (inferred from Fig. 2 curve for VRWM ≈13 V). This value remains stable below 10 V reverse bias and makes the device suitable for DC and low-speed signal lines, not RF or USB 2.0.
