Diodes Incorporated AR30N60PPA-13

Overview

AR30N60PPA-13 from Diodes Incorporated is a high-performance active/synchronous rectifier IC integrating a 60V/30A MOSFET and controller for secondary-side rectification in AC/DC converters with output voltage <10V. It features -4mV turn-off threshold, DFN6040-22 package, 15mΩ typical R_DS(ON), and supports DCM/CCM/QR topologies in flyback and LLC-resonant power supplies.

For engineers reviewing the AR30N60PPA-13 datasheet, AR30N60PPA-13 pinout, AR30N60PPA-13 application, or AR30N60PPA-13 equivalent, key selection criteria include synchronous rectifier timing precision, light-load detection capability, SYNC-driven shoot-through prevention, and thermal robustness up to +150°C junction temperature.

Technical Context

The AR30N60PPA-13 implements near-zero-voltage sensing with programmable T_ON (0.26–3.75µs) and T_OFF (0.3–1.3µs) timers, enabling precise MOSFET gate control synchronized to primary-side switching via the SYNC input. Its internal 4.5V AVDD regulator powers logic and gate driver stages independently of V_CC.

It integrates fault protection including over-temperature shutdown (T_OTP = +150°C), UVLO (2.8–3.2V hysteresis), and arming threshold validation (V_THARM = 1.3–1.7V) before MOSFET turn-on. The SFB pin provides opto-coupler-compatible feedback for secondary-side regulation in SSR architectures.

Key Specifications

Pinout & Package

FAQ

What is the recommended PCB layout for thermal performance?

Mount the DFN6040-22 package on a 2oz copper board with ≥25mm² exposed GND and VD pads connected via ≥6 thermal vias each to inner ground planes. Maintain ≥0.5mm clearance between VD and VS traces to avoid creepage issues at 60V. Follow Diodes' layout guidelines in DS37287 Figure 17 for optimal θ_JA = 50°C/W.

How does the SYNC pin prevent shoot-through in CCM operation?

The SYNC pin pulls down internally when the primary-side MOSFET gate goes high, forcing immediate AR30N60PPA-13 turn-off before the primary switch fully conducts. This creates a controlled dead-time, verified by T_SDLY = 40–70ns propagation delay, eliminating overlap between primary and secondary conduction in CCM.

Can AR30N60PPA-13 operate without the SYNC connection?

Yes - it functions in standalone V_DS-sensing mode for DCM/QR applications, but SYNC is mandatory for CCM operation to prevent shoot-through. Without SYNC, the device relies solely on V_THOFF detection, increasing risk of simultaneous conduction in high-frequency, high-duty-cycle flyback designs.

What failure modes does the SFB pin report to the primary controller?

The SFB pin reports over-temperature (OTP), UVLO, and open-circuit faults by pulling up its voltage to AVDD level. In normal operation, it sinks current into an opto-coupler LED; during fault, it stops sinking, causing the opto-coupler to disable the primary controller - providing fail-safe shutdown without external logic.
