Product details

Overview

STP7NB60 from STMicroelectronics is an N-channel 600 V, 7.2 A PowerMESH™ MOSFET in TO-220 package with typical R_DS(on) of 1.0 Ω, 100% avalanche tested, and optimized for high-speed switching in SMPS and motor drive inverters.

For engineers reviewing the STP7NB60 datasheet, STP7NB60 pinout, STP7NB60 application, or STP7NB60 equivalent, key selection criteria include its 600 V V_DSS, 7.2 A continuous drain current at T_C = 25 °C, 1.0 Ω R_DS(on), 4.5 V/ns dv/dt capability, and 580 mJ single-pulse avalanche energy - all critical for rugged offline power conversion designs.

Technical Context

This MOSFET employs ST's proprietary high-voltage MESH OVERLAY™ process and strip-layout cell design to achieve low on-resistance per die area while maintaining robust edge termination. Its gate charge (Q_g = 30–45 nC) and minimized intrinsic capacitances (C_iss = 1250–1625 pF, C_oss = 165–223 pF) enable fast, efficient switching under hard-switching conditions.

The device integrates a source-drain diode with 7.2 A continuous rating, 530 ns reverse recovery time (trr), and 4.5 µC Q_rr at 150 °C - supporting synchronous rectification and unclamped inductive load handling without external freewheeling diodes in many topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	600 V - supports primary-side switching in universal-input AC-DC converters up to 400 V DC bus with margin
R_DS(on)	1.0 Ω typ. - enables <1.0 W conduction loss at 3.2 A RMS in 50 W–150 W SMPS designs
I_D (cont.)	7.2 A at T_C = 25 °C - suitable for medium-power flyback/LLC primary switches with heatsink
Q_g	30–45 nC - determines gate driver strength requirement; compatible with standard 1-A peak drivers
E_AS	580 mJ - withstands repetitive unclamped inductive switching events in motor drive H-bridge legs
dv/dt	4.5 V/ns - suppresses false turn-on during high-slew-rate transients in noisy industrial environments
T_j(max)	150 °C - allows operation in sealed enclosures with limited airflow when derated per R_thj-case = 1.0 °C/W

Pinout & Package

TO-220 package: insulated case, vertical mounting, 3-pin through-hole configuration with metal tab (drain) electrically connected to Pin 2. Standard lead finish: matte tin.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Source terminal	Low-side reference node; connects to ground or low-side switch node; carries full load current
Pin 2 (Drain)	Drain terminal / Case	High-voltage output node; electrically tied to metal tab; requires isolation washer when mounted to heatsink
Pin 3 (Gate)	Control input	High-impedance MOS gate; requires 10 V drive for full enhancement; sensitive to ESD and ringing

Key Features

Feature	Design Value
PowerMESH™ cell architecture	Delivers lowest R_DS(on)/mm² among 600 V MOSFETs of same die size, reducing conduction loss density
100% avalanche tested	Guarantees robustness against inductive kickback without derating - eliminates need for snubbers in many welder inverters
Minimized C_iss, C_oss, C_rss	Reduces switching losses and EMI generation; enables >100 kHz operation in PFC stages
Extremely high dv/dt capability	4.5 V/ns rating prevents spurious turn-on during fast voltage transitions in half-bridge configurations
Integrated source-drain diode	Enables body-diode commutation in LLC resonant converters without discrete diode cost or layout area

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage power switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP8NK60Z	600 V, 8 A, R_DS(on) = 0.75 Ω typ., Zener-protected gate, higher Q_g (52 nC)	Better conduction efficiency but slower switching; requires stronger gate driver	Select when lower conduction loss dominates over switching loss, e.g., in <50 kHz fixed-frequency SMPS
FQP7N60C	600 V, 7 A, R_DS(on) = 1.2 Ω typ., no avalanche rating, TO-220 package	Lacks guaranteed avalanche ruggedness; unsuitable for unclamped inductive loads	Acceptable only in non-inductive or snubber-protected applications where cost is primary constraint

Compared with STP8NK60Z and FQP7N60C, STP7NB60 offers balanced trade-offs: superior avalanche reliability versus FQP7N60C and lower gate charge versus STP8NK60Z - making it optimal for cost-sensitive, medium-frequency industrial SMPS requiring field-proven ruggedness.

FAQ

What is the maximum safe operating junction temperature for STP7NB60?

The absolute maximum junction temperature is 150 °C, as specified in Table 3. Operation above this limit risks permanent degradation of the silicon structure and oxide integrity. Thermal design must ensure that steady-state T_j remains below 150 °C under worst-case ambient, power dissipation, and heatsink conditions - using R_thj-case = 1.0 °C/W and derating factor of 1.0 W/°C.

Does STP7NB60 require a gate resistor, and what value is recommended?

Yes - a gate resistor is required to control dV/dt and prevent oscillation. For typical 10–20 kHz SMPS use, a 10–22 Ω series resistor between driver and gate is recommended. This limits peak gate current to ~0.5 A (given 10 V drive and 45 nC Q_g) and damps ringing caused by L_g-C_iss resonance, especially critical due to the device's high dv/dt capability.

Can STP7NB60 be used in parallel configurations?

Parallel operation is not recommended without individual source resistors and matched PCB layout. The device exhibits positive temperature coefficient for R_DS(on) (per Figure 14), which aids current sharing, but gate threshold variation (3–5 V) and unequal parasitic inductance can cause dynamic imbalance. If paralleling is unavoidable, use identical gate drive paths, Kelvin-source connections, and 0.1–0.2 Ω source resistors per device.

Is the TO-220 package electrically insulated, and how should it be mounted?

The TO-220 package has an electrically conductive metal tab tied directly to the drain (Pin 2). It is not insulated - mounting to a heatsink requires an isolating pad (e.g., mica or polymer film) plus shoulder washer to prevent shorting. Thermal interface material must be applied between pad and heatsink. Mechanical torque on the mounting screw must not exceed 0.6 N·m to avoid package cracking.
