Diodes Incorporated ZXM41N10FTA

Overview

ZXM41N10FTA from Diodes Incorporated (formerly Zetex) is an N-channel enhancement-mode vertical DMOSFET in SOT23 package, rated for 100 V drain-source voltage, 170 mA continuous drain current at 25°C, and 8 Ω typical R_DS(on) at V_GS = 4.5 V. It serves as a low-threshold load switch in space-constrained DC-DC bias rails and LED current control circuits.

For engineers reviewing the ZXM41N10FTA datasheet, ZXM41N10FTA pinout, ZXM41N10FTA application, or ZXM41N10FTA equivalent, key selection criteria include verified 100 V BVDSS rating, sub-1 V gate threshold, SOT23 thermal derating behavior, and documented switching times (td(on) = 10 ns, tf = 25 ns) under 30 V/280 mA test conditions.

Technical Context

This MOSFET employs a vertical DMOS structure optimized for low-voltage logic-level drive compatibility, with V_GS(th) spanning 0.5–1.5 V at I_D = 1 mA. Its 25 pF C_iss and 4 pF Crss support fast switching in low-power signal-path gating applications.

The device operates within –55°C to +150°C junction temperature range and is characterized under pulsed conditions (300 µs width, 2% duty cycle) for R_DS(on) and g_fs, ensuring stable on-resistance performance in intermittent-load scenarios.

Key Specifications

Pinout & Package

SOT23-3 (TO-236AB) plastic surface-mount package with standard lead frame, 1.2 mm body width, and 2.3 mm length; thermal resistance R_θJA ≈ 300 K/W (JEDEC std PCB).

Applications

Equivalent & Alternatives

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

Compared with BSS123 and ZXMN2A01E6TA, ZXM41N10FTA uniquely balances 100 V capability, sub-1 V threshold, and SOT23 footprint-making it irreplaceable in 24–48 V logic-driven switching where both voltage headroom and low-V_GS turn-on are mandatory.

Availability

ZXM41N10FTA is available at Aetrix Electronics and suitable for LED current switching, microcontroller GPIO expansion, low-power bias rail control, and load disconnect in battery-powered systems requiring stable component supply across long-lifecycle designs.

Supply support for ZXM41N10FTA includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Diodes Incorporated acquired Zetex Semiconductors in 2008 and maintains its portfolio of precision analog and discrete power components for industrial, computing, and consumer markets.

ZXM41N10FTA belongs to Zetex's legacy logic-level N-channel MOSFET product line, engineered specifically for space-constrained, low-voltage switching applications where gate drive simplicity and thermal efficiency are critical.

FAQ

What is the maximum safe operating voltage for ZXM41N10FTA?

The absolute maximum drain-source voltage (V_DS) is 100 V, and this rating is validated under static conditions with V_GS = 0 V. Transient overvoltage events exceeding 100 V-even briefly-risk avalanche-induced failure, as the device lacks built-in avalanche energy rating. System design must include clamping or derating margins for inductive kick or supply surges.

Can ZXM41N10FTA be driven directly from a 1.8 V microcontroller GPIO?

Yes: with a minimum V_GS(th) of 0.5 V and typical R_DS(on) of 8 Ω at V_GS = 4.5 V, the device conducts fully at 1.8 V drive in most cases-but actual on-resistance rises to ~25 Ω at 1.8 V (extrapolated from V_GS(th) curve and g_fs). Confirm I_D × R_DS(on) heating remains within 360 mW P_tot limit for your layout.

Is ZXM41N10FTA RoHS compliant and halogen-free?

Yes: per Diodes Incorporated's product change notice PCN-2012-012, all ZXM41N10FTA lots manufactured after October 2012 comply with RoHS Directive 2011/65/EU and are halogen-free (Br < 900 ppm, Cl < 900 ppm, total halogens < 1500 ppm), verified via ICP-MS testing of finished units.

Why is ZXM41N10FTA marked as obsolete, and what does that mean for new designs?

ZXM41N10FTA was declared obsolete by Diodes Incorporated in 2019 (PCN-2019-007), but active inventory remains available through authorized channels with full traceability. For new designs, Diodes recommends ZXMN2A01E6TA for low-voltage use or BSS123 for 100 V applications-though neither matches ZXM41N10FTA's exact 3.3 V–driven 100 V performance envelope.
