Product details

Overview

AONS36346 from Alpha & Omega Semiconductor is a 30V, 60A N-channel Trench Power MOSFET in DFN5x6 package, featuring R_DS(ON) < 5.5 mΩ at V_GS = 10 V and < 9.5 mΩ at V_GS = 4.5 V, with 100% UIS and R_g tested, optimized for high-efficiency DC/DC converters in computing and telecom power supplies.

For engineers reviewing the AONS36346 datasheet, pinout, applications, or equivalent options, key selection criteria include its low gate charge (Q_g(10V) = 10–20 nC), high current capability (I_D = 60 A), thermal performance (R_θJC = 4 °C/W), body-diode robustness (E_AS = 26.5 mJ), and RoHS/halogen-free compliance.

Technical Context

The AONS36346 employs Trench Power MOSFET technology to achieve low R_DS(ON) and fast switching, with gate threshold voltage V_GS(th) = 1.2–2.1 V and forward transconductance g_FS = 54 S. Its dynamic parameters include t_d(on) = 5 ns, t_r = 2.5 ns, t_d(off) = 17 ns, and t_f = 2.5 ns under standard test conditions (V_GS = 10 V, V_DS = 15 V, R_GEN = 3 Ω).

Thermally, it supports junction temperatures from –55 °C to 150 °C, with R_θJC = 4 °C/W and R_θJA = 50 °C/W (1 in² FR-4, 2 oz Cu). It delivers 100% avalanche-rated energy (E_AS = 26.5 mJ, L = 0.01 mH) and features a low reverse recovery charge Q_rr = 13 nC and t_rr = 10 ns for synchronous rectification use cases.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Infineon BSC014N04LS6	R_DS(ON) = 1.4 mΩ @ 10 V (lower), but 40 V V_DS, larger PG-TSDSON-8 package (5.15 × 6.2 mm)	Better conduction loss in 12 V systems; less suitable for 30 V bus margin-critical designs	Prefer when lowest R_DS(ON) dominates and board space allows larger footprint
Vishay SiR626DP	R_DS(ON) = 5.2 mΩ @ 10 V (similar), 30 V rating, same DFN5×6 package, Q_g = 22 nC (higher)	Higher gate charge increases driver loss; identical thermal and layout compatibility	Choose when supply chain diversification is required and gate drive strength permits higher Q_g

Compared with AONS36346, BSC014N04LS6 offers lower conduction loss but sacrifices 30 V margin and increases board area, while SiR626DP matches voltage and footprint but demands stronger gate drive due to +10% Q_g.

FAQ

What is the maximum continuous drain current rating for AONS36346 at TC = 100°C?

The AONS36346 has a maximum continuous drain current I_D of 30 A at case temperature T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits under steady-state conditions with proper heatsinking, and is distinct from the 60 A rating at T_C = 25 °C. The AONS36346 must be mounted to minimize thermal resistance to maintain safe junction temperature below 150 °C.

Does AONS36346 support 4.5 V logic-level gate drive?

Yes, the AONS36346 supports 4.5 V gate drive, with R_DS(ON) guaranteed at < 9.5 mΩ under V_GS = 4.5 V conditions. Its gate threshold voltage V_GS(th) ranges from 1.2 V to 2.1 V, ensuring full enhancement with standard 3.3 V or 5 V logic outputs. The AONS36346 also specifies Q_g(4.5 V) = 5–10 nC, confirming suitability for low-voltage gate driver ICs in compact power designs.

What is the body diode forward voltage of AONS36346 at IS = 40 A?

The body diode forward voltage V_SD of the AONS36346 is specified as 0.7–1.0 V at I_S = 40 A and T_J = 25 °C. This parameter is critical for evaluating reverse recovery behavior and conduction loss in synchronous rectifier or freewheeling configurations. The AONS36346's V_SD remains stable across temperature, supporting predictable performance in high-current, high-temperature POL applications.

Is AONS36346 qualified for automotive applications?

No, the AONS36346 is not AEC-Q101 qualified and is not intended for automotive applications. Its qualification level aligns with industrial and computing standards, with operating junction temperature range of –55 °C to 150 °C and 100% UIS testing per JEDEC JESD24-11. For automotive-grade equivalents, designers should consult AOS's AEC-Q101-qualified portfolio; the AONS36346 is explicitly rated for computing, telecom, and industrial power systems only.

How is thermal performance characterized for AONS36346 in still-air conditions?

The AONS36346's R_θJA is characterized as 50 °C/W under JEDEC-standard conditions: mounted on 1 in² FR-4 board with 2 oz copper, in still air at T_A = 25 °C. This value enables accurate ambient-referenced thermal design for low-to-medium power applications. For high-power use, the lower R_θJC = 4 °C/W allows direct heatsink coupling-critical for achieving full 60 A current capability in the AONS36346 without exceeding T_J(MAX) = 150 °C.
