Product details

Overview

BUK7613-100E from Nexperia is a standard-level N-channel TrenchMOS FET in SOT404 (D2PAK) package, rated for 100 V V_DS, 72 A continuous drain current at T_mb = 25 °C, and 175 °C junction temperature. It features 10.2 mΩ typical R_DS(on) at V_GS = 10 V and ID = 20 A, AEC-Q101 qualification, and repetitive avalanche capability - deployed in automotive transmission control and start-stop micro-hybrid power switching.

For engineers reviewing the BUK7613-100E datasheet, BUK7613-100E pinout, BUK7613-100E application, or BUK7613-100E equivalent, key selection criteria include its true standard-level gate (V_GS(th) > 1 V at 175 °C), thermally robust 0.82 K/W R_th(j-mb), and 121 mJ unclamped avalanche energy rating under defined test conditions.

Technical Context

This MOSFET employs TrenchMOS technology to achieve low on-resistance and fast switching with Q_GD = 25.4 nC (typ) and t_r = 34 ns (typ). Its gate threshold voltage remains functional up to 175 °C (V_GS(th) ≥ 1 V), enabling reliable operation in thermally demanding engine-bay environments without gate driver level-shifting.

The device integrates a source-drain diode with V_SD = 0.83 V (typ) at I_S = 20 A and T_j = 25 °C, and supports pulsed peak drain current of 288 A (t_p ≤ 10 µs). Thermal design leverages the mounting base (connected to drain) for direct heatsink coupling, yielding R_th(j-mb) = 0.82 K/W.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V maximum - supports 48 V automotive systems with margin against load-dump transients
R_DS(on)	10.2 mΩ typ at V_GS = 10 V, I_D = 20 A, T_j = 25 °C - enables <1.5 W conduction loss at 38 A
I_D (cont)	72 A at T_mb = 25 °C - delivers high-current motor/solenoid drive with minimal PCB copper area
E_AS	121 mJ non-repetitive avalanche energy - withstands inductive kickback in transmission solenoid circuits
R_th(j-mb)	0.82 K/W - allows direct thermal path to heatsink, critical for sustained 51 A operation at T_mb = 100 °C
Q_GD	25.4 nC typ - determines Miller plateau duration and gate drive power requirement during hard-switching
V_GS(th)	≥1 V at T_j = 175 °C - ensures turn-on compatibility with standard 5 V/12 V logic without gate boosting

Pinout & Package

Package: SOT404 (D2PAK), plastic single-ended surface-mounted package with 3 leads (one lead cropped); mounting base electrically connected to drain for low-inductance thermal and power path.

Pin/Terminal	Circuit Role	Design Meaning
1 (G)	Gate	Controls channel conduction; requires 10 V drive for full enhancement; 0.96 Ω typical gate resistance
2 (D)	Drain	Main high-side power terminal; internally bonded to mounting base for thermal dissipation and low-inductance return
3 (S)	Source	Power return path and reference for gate drive; forms cathode of integrated body diode
mb	Mounting Base	Electrically tied to drain; provides primary thermal interface to heatsink; must be soldered to copper pour

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive underhood use per stress test requirements including temperature cycling, HTRB, and UHAST
Repetitive avalanche rated	Rated for repeated unclamped inductive switching events up to specified E_AS limit without degradation
175 °C junction rating	Enables operation in engine control units and transmission modules where ambient exceeds 125 °C
True standard-level gate	V_GS(th) ≥ 1 V at 175 °C ensures reliable turn-on with conventional 5 V or 12 V microcontroller GPIO or driver ICs
TrenchMOS technology	Delivers optimized trade-off between R_DS(on), Q_G, and ruggedness - critical for high-efficiency 12/24/48 V power stages

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel automotive power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N10F7	100 V, 220 A, 3.2 mΩ R_DS(on), 5x6 mm PowerFLAT™ package; higher current, lower R_DS(on), but no AEC-Q101 certification stated	Requires larger gate drive (Q_G = 120 nC) and lacks documented avalanche rating	Preferred for space-constrained 48 V systems needing lower conduction loss; verify qualification status for automotive production
IRF1404ZPBF	40 V, 202 A, 3.7 mΩ R_DS(on), TO-220AB; not AEC-Q101 qualified, lower V_DS rating	Unsuitable for 48 V or load-dump scenarios; limited to 12 V/24 V non-safety-critical functions	Only acceptable for cost-sensitive industrial motor drives where automotive qualification is unnecessary

Compared with STL220N10F7 and IRF1404ZPBF, BUK7613-100E uniquely combines AEC-Q101 compliance, 100 V rating, and 175 °C operation - making it the only option qualified for thermally aggressive, safety-relevant automotive power switching where reliability and transient margin are mandatory.

FAQ

Is BUK7613-100E suitable for synchronous rectification in 48 V automotive DC-DC converters?

Yes. Its 100 V V_DS rating provides sufficient margin against 48 V bus transients (e.g., ISO 16750-2 load dump up to 87 V), and its 10.2 mΩ R_DS(on) minimizes conduction loss. The integrated source-drain diode (V_SD = 0.83 V typ) supports freewheeling, though external Schottky clamping may be used for higher efficiency at light loads.

What is the maximum continuous drain current at 100 °C mounting base temperature?

Per Figure 1 in the datasheet, the maximum continuous drain current is 51 A at T_mb = 100 °C and V_GS = 10 V. This derating reflects thermal limits imposed by R_th(j-mb) = 0.82 K/W and junction temperature cap of 175 °C.

Does BUK7613-100E require a gate resistor for automotive PWM switching at 20 kHz?

Yes. A series gate resistor (typically 5–10 Ω) is recommended to damp ringing caused by L_D = 2.5 nH and L_S = 7.5 nH internal inductances, especially when driving inductive loads. This prevents spurious turn-on due to dV/dt coupling and controls switching speed to balance EMI and switching loss.

Can the mounting base be left unconnected in non-thermal applications?

No. The mounting base is electrically connected to the drain terminal and must be properly soldered to a PCB copper pour or heatsink. Leaving it floating violates safe operating area limits, risks voltage breakdown, and eliminates the primary thermal path - leading to premature thermal runaway even at moderate currents.
