Product details

Overview

PHP73N06T from NXP Semiconductors (formerly Philips) is an N-channel enhancement-mode TrenchMOS™ power MOSFET in SOT78 (TO-220AB) package, rated for 60 V V_DS, 73 A I_D (DC at T_mb = 25 °C), and 149 W total power dissipation. It delivers 12 mΩ R_DS(on) at V_GS = 10 V and I_D = 25 A, enabling high-efficiency switching in DC-DC converters and SMPS primary-side switches.

For engineers reviewing the PHP73N06T datasheet, PHP73N06T pinout, PHP73N06T application, or PHP73N06T equivalent, key selection criteria include its low on-resistance, avalanche ruggedness (125 mJ E_AS), thermal resistance to mounting base (0.9 K/W), and compatibility with standard-level gate drive (V_GS(th) = 2–4 V).

Technical Context

This device uses TrenchMOS™ technology to achieve low R_DS(on) and fast switching with Q_g(tot) = 54 nC and t_r = 79 ns (typ). Its gate threshold voltage (2–4 V at T_j = 25 °C) supports direct logic-level drive from 5 V microcontrollers or PWM controllers without level-shifting.

The integrated source-drain diode exhibits V_SD = 0.85 V (typ) at I_S = 25 A and t_rr = 54 ns (typ), supporting synchronous rectification and freewheeling in buck and flyback topologies. Avalanche capability is specified under unclamped inductive load conditions (E_AS = 125 mJ).

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - Maximum drain-source blocking voltage; suitable for 48 V input systems and 24 V industrial rails.
I_D (DC)	73 A at T_mb = 25 °C - Continuous current rating with heatsink; derates to 52 A at T_mb = 100 °C.
R_DS(on)	12 mΩ (typ) at V_GS = 10 V, I_D = 25 A - Low conduction loss enables <1.5 W dissipation at 30 A, reducing heatsink size.
E_AS	125 mJ - Non-repetitive avalanche energy; supports robust operation during inductive turn-off transients.
Q_g(tot)	54 nC - Total gate charge determines driver strength requirement; compatible with common 1 A gate drivers.
R_th(j-mb)	0.9 K/W - Junction-to-mounting-base thermal resistance; enables efficient heat transfer to heatsink without thermal interface material dependency.
V_GS(th)	2–4 V at T_j = 25 °C - Standard-level gate threshold allows direct drive from 3.3 V/5 V logic with margin.

Pinout & Package

SOT78 (TO-220AB) plastic single-ended package with isolated mounting base connected internally to drain. Mounting base serves as both mechanical heatsink interface and electrical drain terminal.

Pin	Circuit Role	Design Meaning
1	Gate (G)	Control terminal; requires ≤±20 V gate-source voltage; low input capacitance (C_iss = 1848 pF typ) eases driving.
2	Drain (D)	Main power output terminal; electrically tied to mounting base; must be isolated from PCB ground plane unless drain-referenced topology.
3	Source (S)	Power return path and reference for gate drive; forms common node with load in low-side switch configuration.

Key Features

Feature	Design Value
TrenchMOS™ technology	Enables 12 mΩ R_DS(on) in TO-220AB, reducing conduction losses by >30% vs. planar MOSFETs of same die size.
Low gate charge (54 nC)	Reduces switching losses and driver power consumption; supports >200 kHz operation with minimal gate drive overhead.
Avalanche-rated (125 mJ)	Eliminates need for external snubbers in hard-switched inductive loads, improving system reliability without added components.
Integrated body diode (t_rr = 54 ns)	Supports freewheeling and synchronous rectification in DC-DC converters without external Schottky diode.
Mounting base as drain	Provides low-inductance, high-current drain connection and direct thermal path to heatsink-no solder joint thermal bottleneck.

IRFZ44NPBF	49 A/55 V, R_DS(on) = 28 mΩ (V_GS = 10 V), TO-220, lower cost, no avalanche rating	Lower current/voltage rating and no specified E_AS; unsuitable for inductive hard-switching or overload protection	Acceptable only in low-stress, non-avalanche-critical 24 V/30 A applications with conservative derating.

Compared with STP75NF75 and IRFZ44NPBF, PHP73N06T offers optimal balance of 60 V rating, 73 A current capacity, 12 mΩ on-resistance, and verified 125 mJ avalanche ruggedness-making it uniquely suited for industrial SMPS and motor drives where reliability under transient stress is mandatory.

FAQ

What is the maximum continuous drain current rating for PHP73N06T?

The PHP73N06T supports 73 A DC drain current at mounting base temperature (T_mb) = 25 °C and V_GS = 10 V. This rating decreases to 52 A at T_mb = 100 °C per Figure 2 in the datasheet. Derating must follow the normalized curve in Figure 2, not linear interpolation, due to thermal saturation effects in the TO-220AB package.

Does PHP73N06T have avalanche capability, and how is it specified?

Yes, PHP73N06T is rated for non-repetitive avalanche energy (E_AS) of 125 mJ under unclamped inductive load conditions: I_AS = 50 A, t_p = 0.1 ms, V_DD ≤ 25 V, R_GS = 50 Ω, V_GS = 5 V, and starting junction temperature of 25 °C. This specification is validated per JEDEC standards and enables robust operation during inductive turn-off without external protection.

What is the gate-source threshold voltage range for PHP73N06T?

The PHP73N06T has a gate-source threshold voltage (V_GS(th)) of 2–4 V at T_j = 25 °C and 1–? V at T_j = 175 °C (min only specified). This standard-level threshold allows direct drive from 3.3 V or 5 V logic outputs, though full enhancement (R_DS(on) minimization) requires ≥10 V gate drive per datasheet test conditions.

Can PHP73N06T be used in surface-mount designs?

No-PHP73N06T is packaged exclusively in SOT78 (TO-220AB), a through-hole plastic package with a metal mounting base designed for heatsink attachment. The PHB73N06T variant uses SOT404 (D2-PAK) for surface-mount use, but PHP73N06T itself is not SMT-compatible and requires vertical mounting with screw or clip heatsinking.

What is the thermal resistance from junction to mounting base for PHP73N06T?

The PHP73N06T has a maximum thermal resistance from junction to mounting base (R_th(j-mb)) of 0.9 K/W, as specified in Table 4. This value assumes proper mechanical contact between the mounting base and heatsink; actual performance depends on thermal interface material quality and clamping force, but the 0.9 K/W rating provides a verified worst-case boundary for thermal design.
