Microchip Technology TN0604N3-G-P005

Overview

TN0604N3-G-P005 from Microchip Technology is an N-channel enhancement-mode vertical DMOS FET in a 3-lead TO-92 package, designed for logic-level switching with 1.6 V maximum gate threshold voltage, 40 V drain-to-source breakdown voltage, and 0.75 Ω typical R_DS(ON) at V_GS = 10 V. It serves as a low-threshold power switch in battery-operated systems, solid-state relays, and photovoltaic drives.

For engineers reviewing the TN0604N3-G-P005 datasheet, TN0604N3-G-P005 pinout, TN0604N3-G-P005 application, or TN0604N3-G-P005 equivalent, key selection criteria include verified low V_GS(th) (≤1.6 V), guaranteed R_DS(ON) ≤0.75 Ω at 10 V drive, thermal stability up to +150°C ambient, and TO-92 compatibility with TTL/CMOS logic interfaces.

Technical Context

This device uses a vertical DMOS structure with silicon-gate process to combine bipolar-like power handling with MOS advantages: high input impedance (>10¹² Ω), low input capacitance (140 pF typ), and positive temperature coefficient for inherent thermal stability. It is free from secondary breakdown and thermal runaway.

Its gate threshold voltage exhibits –3.8 to –4.5 mV/°C drift, and R_DS(ON) increases by 0.5–0.75 %/°C - enabling predictable derating across –55°C to +150°C operating range. The integrated body diode supports bidirectional current flow with 1.2–1.8 V forward drop at 1.5 A.

FAQ

What is the maximum gate-to-source voltage rating for TN0604N3-G-P005?

The absolute maximum gate-to-source voltage for TN0604N3-G-P005 is ±20 V. This rating applies across the full operating temperature range (–55°C to +150°C). Exceeding this voltage risks permanent gate oxide damage. Designers should ensure gate drive circuits include clamping (e.g., Zener diodes) when interfacing with higher-voltage controllers or noisy environments. The TN0604N3-G-P005 datasheet specifies that all DC parameters are 100% tested at 25°C under pulse conditions (300 µs, 2% duty cycle).

Does TN0604N3-G-P005 have an integrated body diode, and what are its characteristics?

Yes, TN0604N3-G-P005 includes an intrinsic body diode with a forward voltage drop (V_SD) of 1.2–1.8 V at 1.5 A and reverse recovery time (t_rr) of 300 ns typical. This diode enables freewheeling current paths in inductive switching applications like relay drivers and motor controls. Its parameters are specified at V_GS = 0 V, confirming operation independent of gate bias. The TN0604N3-G-P005 body diode is not optimized for fast recovery but is sufficient for <100 kHz switching frequencies.

Can TN0604N3-G-P005 be used in linear (analog) amplifier configurations?

TN0604N3-G-P005 is characterized for switching operation and not optimized for linear-mode amplification. While its transconductance (g_FS) is specified at 500–800 mmho, the device lacks guaranteed gain flatness, distortion metrics, or SOA curves for analog biasing. Its Safe Operating Area (SOA) is defined only for pulsed switching per Figure 2-3. For analog signal paths, dedicated small-signal MOSFETs or JFETs with proven linearity specs are recommended over TN0604N3-G-P005.

What is the thermal resistance from junction-to-ambient (θ_JA) for TN0604N3-G-P005 in its TO-92 package?

The junction-to-ambient thermal resistance (θ_JA) for TN0604N3-G-P005 in the 3-lead TO-92 package is 132 °C/W, measured under standard JEDEC test conditions (still air, no heatsink). This value assumes the device is mounted on a standard FR-4 PCB with minimal copper area. Derating curves on page 5 of the TN0604N3-G-P005 datasheet show power dissipation drops to 0.3 W at +100°C ambient, confirming thermal design margins must be validated for each layout.

Is TN0604N3-G-P005 suitable for driving capacitive loads such as piezoelectric actuators?

TN0604N3-G-P005 can drive moderate capacitive loads due to its 140 pF input capacitance and 2.1 A ID(ON) at 5 V gate drive, but it lacks explicit characterization for high dv/dt or large charge/discharge currents. Its rise/fall times (6 ns/20 ns) suggest suitability for ≤10 nF loads at ≤1 MHz. For piezo actuator drivers requiring >100 V/ns slew rates or >100 nF capacitance, dedicated high-speed gate drivers paired with higher-current MOSFETs are advised instead of relying solely on TN0604N3-G-P005.
