Product details
Overview
P6SMAJ16ADF-13 from Diodes Incorporated is a 600W surface-mount transient voltage suppressor (TVS) diode designed for unidirectional overvoltage protection in DC power rails and signal lines. It features a reverse standoff voltage of 16 V, breakdown voltage range of 17.8–20.5 V at 1.0 mA test current, clamping voltage of 26.0 V at 23.1 A peak pulse current, and D-FLAT package for space-constrained PCB layouts. Used in automotive infotainment power inputs and industrial sensor interface protection.
For engineers reviewing the P6SMAJ16ADF-13 datasheet, P6SMAJ16ADF-13 pinout, P6SMAJ16ADF-13 application, or P6SMAJ16ADF-13 equivalent, key selection criteria include clamping voltage margin relative to protected IC VMAX, peak pulse current capability under IEC 61000-4-5 surge waveforms, thermal resistance to PCB copper pad area, and RoHS/Green compliance status for end-product certification.
Technical Context
This unidirectional TVS operates as a clamping device triggered by reverse-biased avalanche breakdown. Its glass-passivated die ensures stable leakage performance and repeatable breakdown characteristics across temperature. The D-FLAT package provides low thermal resistance (57–64 °C/W junction-to-terminal) when mounted on defined FR-4 copper pads.
It responds to 10/1000 µs transients with sub-nanosecond turn-on, limiting induced voltage to ≤26.0 V during 23.1 A surges. Steady-state power dissipation is rated at 1.5 W at 75 °C lead temperature, supporting continuous operation in thermally managed environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - Sustains single 10/1000 µs surges up to this energy level without failure |
| Reverse Standoff Voltage (VRWM) | 16 V - Maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 17.8–20.5 V @ 1.0 mA - Confirmed avalanche initiation window for reliable clamping onset |
| Clamping Voltage (VC) | 26.0 V @ 23.1 A - Maximum voltage seen by downstream circuit during specified surge event |
| Peak Pulse Current (IPP) | 23.1 A - Peak current handled at VC; defines surge immunity level per IEC 61000-4-5 |
| Thermal Resistance (RθJT) | 57–64 °C/W - Junction-to-terminal thermal path varies with PCB copper pad size per JEDEC mounting conditions |
| Leakage Current (IR) | ≤1.0 µA @ 16 V - Ensures minimal standby power loss and signal integrity in high-impedance nodes |
Pinout & Package
Package: D-FLAT - Low-profile surface-mount plastic package (4.65 mm × 2.80 mm × 1.10 mm), UL 94V-0 rated, with cathode band polarity indicator and matte tin-plated copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Anode-side connection point for reverse-biased clamping | Connected to protected line; conducts during overvoltage to shunt current to ground |
| 2 (Anode) | Reference/ground return path | Typically tied to system ground plane; completes clamping current path during transient events |
Key Features
| Feature | Design Value |

| 600 W peak pulse rating | Supports Level 4 IEC 61000-4-5 (4 kV/2 Ω) surge testing on 12 V supply rails |
| D-FLAT low-profile package | Reduces board footprint by >40% vs. SMA; enables routing under adjacent components |
| RoHS & Halogen-free compliance | Fulfills EU RoHS 2 and IPC-1752A environmental requirements for automotive and industrial end equipment |
| Fast response time | Sub-nanosecond turn-on limits voltage overshoot during ESD and lightning-induced transients |
Applications
| Automotive Body Control Module (BCM) Power Input | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: Protects 12 V supply rail of BCM against load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between fuse output and DC-DC converter input.

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-Q | Same 16 V VRWM, but 400 W peak power (vs. 600 W); higher VC = 27.7 V @ 14.4 A | Limited to lower-energy surges (e.g., IEC 61000-4-2 only); unsuitable for ISO 7637-2 load dump | Select when cost sensitivity outweighs surge margin and board space allows larger footprint |
| 1.5SMC16A | Same 16 V rating, 1500 W peak power, but DO-214AB package (larger, 7.1 mm × 6.2 mm) | Higher surge handling but incompatible with D-FLAT layout; requires redesign of pad stack and keep-out | Choose only if legacy design uses SMA footprint or surge requirement exceeds 600 W |
Compared with SMAJ16A-Q and 1.5SMC16A, P6SMAJ16ADF-13 delivers optimal balance of 600 W surge capacity, ultra-compact D-FLAT footprint, and 26.0 V clamping-enabling robust protection in space-constrained automotive and industrial modules without layout compromise.

FAQ
What is the maximum operating temperature for P6SMAJ16ADF-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 drops linearly to 50% at +125 °C ambient, based on thermal resistance to terminal (57–64 °C/W) and PCB copper pad configuration.
Does P6SMAJ16ADF-13 meet AEC-Q200 stress testing requirements?
No-this part is not AEC-Q200 qualified. It is an industrial-grade TVS with automotive-compatible construction (glass passivation, halogen-free, RoHS), but lacks the extended temperature cycling, humidity bias, and mechanical shock validation required for automotive qualification. For AEC-Q200 designs, consider Diodes' AEC-Q200-qualified AP6SMAJ series.
How does the D-FLAT package affect thermal performance compared to SMA?
The D-FLAT package achieves lower RθJT (57–64 °C/W) than standard SMA (typically ~80–100 °C/W) due to its shorter internal thermal path and optimized copper leadframe geometry. This allows higher sustained power dissipation on small PCB pads, but requires strict adherence to the recommended 0.2" × 0.25" or 1" × 1" copper pad layouts per datasheet Note 8.
Can P6SMAJ16ADF-13 be used for bidirectional transient suppression?
No-it is a unidirectional TVS diode with cathode/anode polarity. Bidirectional operation requires either two devices in series opposition or a dedicated bidirectional part like P6SMBJ16CA. Using this part in reverse-biased forward conduction risks permanent damage due to limited forward surge rating (60 A at 8.3 ms) and no guaranteed symmetrical clamping.
