NXP Semiconductors PHP54N06T,127

Overview

PHP54N06T,127 from NXP Semiconductors is a standard-level N-channel TrenchMOS power MOSFET in TO-220AB (SOT78) package, designed for high-current switching in DC-DC converters and switched-mode power supplies. It delivers 54 A continuous drain current at V_GS = 10 V and 25 °C, features 17 mΩ R_DS(on) at 25 °C, supports 55 V V_DS, and operates up to 175 °C junction temperature.

For engineers reviewing the PHP54N06T,127 datasheet, PHP54N06T,127 pinout, PHP54N06T,127 application, or PHP54N06T,127 equivalent, key selection criteria include thermal performance under mounting-base cooling, gate charge (36 nC total), avalanche ruggedness (115 mJ), and safe operating area (SOA) compliance for pulsed loads up to 217 A.

Technical Context

This device uses TrenchMOS technology to achieve low on-state resistance and fast switching with controlled gate charge distribution-Q_GD = 11.5 nC and Q_GS = 8.4 nC support efficient hard-switching operation. Its SOA is defined for both continuous and pulsed conditions, with peak drain current limited to 217 A for t_p ≤ 10 µs.

The internal mounting base is electrically connected to the drain terminal, enabling direct heatsink coupling with minimal thermal resistance (R_th(j-mb) = 1.2 K/W). The source-drain diode exhibits V_SD = 0.85 V at 20 A and t_rr = 45 ns, supporting synchronous rectification and freewheeling roles in buck and half-bridge topologies.

FAQ

What is the maximum continuous drain current rating for PHP54N06T,127 at 100 °C mounting base temperature?

The PHP54N06T,127 supports 38 A continuous drain current at T_mb = 100 °C, as specified in Table 4 (Limiting values) of the NXP datasheet. This derating reflects thermal constraints at elevated mounting temperatures and must be applied in thermal design calculations alongside R_th(j-mb) = 1.2 K/W to ensure junction temperature remains ≤175 °C.

Does PHP54N06T,127 have a built-in body diode, and what are its key parameters?

Yes, PHP54N06T,127 includes an integral source-drain body diode. Per Table 6, it exhibits V_SD = 0.85 V (typical) at I_S = 20 A and T_j = 25 °C, with reverse recovery time t_rr = 45 ns and recovered charge Q_r = 110 nC under specified test conditions-enabling use in freewheeling and synchronous rectification roles.

What is the gate threshold voltage range for PHP54N06T,127 across its operating temperature range?

The gate-source threshold voltage V_GS(th) for PHP54N06T,127 ranges from 1 V (min) at T_j = 175 °C to 4.4 V (max) at T_j = −55 °C, with a typical value of 3 V at 25 °C (Table 6). This standard-level threshold ensures reliable turn-on with 5 V gate drive while maintaining noise immunity across industrial temperature extremes.

Can PHP54N06T,127 be used in avalanche mode, and what is its rated energy?

Yes, PHP54N06T,127 is rated for non-repetitive drain-source avalanche operation with E_DS(AL)S = 115 mJ under defined conditions (V_GS = 10 V, I_D = 48 A, V_sup ≤55 V, unclamped, R_GS = 50 Ω, T_j(init) = 25 °C). This rating supports robustness against inductive switching transients but does not permit repetitive avalanche operation.

What is the thermal resistance from junction to mounting base for PHP54N06T,127, and how does it impact heatsink selection?

The thermal resistance from junction to mounting base (R_th(j-mb)) for PHP54N06T,127 is 1.2 K/W (maximum), per Table 5. This low value enables efficient heat transfer directly to the heatsink; for example, at 50 W dissipation, the junction-to-mounting-base temperature rise is only 60 K-allowing use of compact passive heatsinks even in 70 °C ambient environments.
