Product details

Overview

ZXMN15A27KTC from Diodes Incorporated is a 150V N-channel enhancement-mode MOSFET in TO252-3L package, rated for 2.6A continuous drain current at 25°C and 650mΩ R_DS(on) at V_GS = 10V, with 55mJ single-pulsed avalanche energy and AEC-Q101 qualification-used in SLIC line drivers for VoIP systems and transformer-driving switch circuits.

For engineers reviewing the ZXMN15A27KTC datasheet, ZXMN15A27KTC pinout, ZXMN15A27KTC application, or ZXMN15A27KTC equivalent, key selection criteria include its 150V V_DSS, low 650mΩ on-resistance at 10V gate drive, 100% production-tested UIS capability, TO252 thermal performance, and RoHS-compliant "Green" packaging.

Technical Context

This MOSFET operates as a unidirectional power switch with integrated body diode, optimized for high-efficiency DC-DC conversion and inductive load switching. Its 2.7V typical gate threshold voltage enables reliable turn-on with standard 3.3V/5V logic-level gate drivers, while low C_iss (169pF) and fast switching times (t_r = 12.7ns, t_f = 13.3ns) reduce switching losses in high-frequency applications.

The device features robust avalanche ruggedness (E_AS = 55mJ, I_AS = 4.3A), validated per JESD22-A115, and thermal design support via R_θJA = 30.2°C/W on 50mm × 50mm 2oz FR4 PCB. Its TO252-3L package provides low R_θJL = 2.06°C/W to the drain lead, enabling efficient heat transfer in surface-mount power stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	150V - supports input rails up to 120V DC with margin for transient spikes in industrial power supplies
R_DS(on)	650mΩ @ V_GS = 10V - limits conduction loss to ≤1.1W at 2.6A, enabling compact thermal design
I_D (continuous)	2.6A @ T_A = 25°C - delivers stable output current in motor control and UPS hold-up circuits
E_AS	55mJ - withstands repetitive inductive kickback in transformer driving and relay snubbing
C_iss	169pF - reduces gate drive power requirement and improves switching efficiency above 100kHz
t_r/t_f	12.7ns / 13.3ns - enables <500kHz PWM operation with minimal dead-time overhead
Q_g	6.6nC - compatible with low-current gate drivers (e.g., TC4420, UCC27531) without external buffering

Pinout & Package

Package: TO252-3L (DPAK), surface-mount, single-sided copper pad layout optimized for thermal dissipation; case material is UL 94V-0 green molding compound; moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
Drain (D)	Main current path from source to load	Exposed tab connected internally to drain; must be soldered to large copper pour for thermal management and EMI shielding
Source (S)	Reference node for gate drive and current return	Low-inductance connection point for sense resistor placement and gate driver ground reference
Gate (G)	Control terminal for channel modulation	High-impedance input requiring <6.6nC charge; sensitive to ESD-requires series resistor and TVS protection in layout

Key Features

Feature	Design Value
100% UIS tested in production	Guarantees avalanche survival under worst-case inductive turn-off without derating or external clamping
AEC-Q101 qualified	Validated for automotive-grade reliability including temperature cycling, HTRB, and uHAST-suitable for under-hood power modules
Low C_oss (64.5pF)	Minimizes capacitive switching loss and improves zero-voltage switching (ZVS) feasibility in resonant topologies
V_SD = 0.95V max	Reduces reverse conduction loss in synchronous rectification and bidirectional power flow applications
RoHS-compliant "Green" construction	No halogens or antimony; meets EU Directive 2011/65/EU and IPC-1752A reporting requirements for supply chain compliance

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP15NF15	150V V_DSS, 150mΩ R_DS(on), TO220 package, no AEC-Q101	Higher R_DS(on) not suitable for high-current SLIC drivers; TO220 requires through-hole assembly and heatsink mounting	Select only if board space allows larger footprint and thermal mass is available; not recommended for surface-mount automotive designs
DMN15H160SFD-13	150V V_DSS, 160mΩ R_DS(on), TSOP-6 package, AEC-Q101 qualified	Lower current rating (1.6A) and smaller package limit use to signal-level switching-not viable for 2.6A transformer drive	Acceptable only in low-power auxiliary rails; insufficient for main power stage due to ID derating and thermal constraints

Compared with STP15NF15 and DMN15H160SFD-13, ZXMN15A27KTC uniquely balances 2.6A current handling, TO252 thermal performance, AEC-Q101 reliability, and 55mJ avalanche rating-making it the only fit for high-stress VoIP SLIC and industrial transformer drive where both ruggedness and surface-mount scalability matter.

FAQ

What is the maximum continuous drain current at 100°C ambient?

At T_A = 100°C, the ZXMN15A27KTC's continuous drain current is derated to approximately 1.1A based on its 30.2°C/W R_θJA and 150°C maximum junction temperature. This value assumes mounting on a 50mm × 50mm 2oz FR4 PCB in still air; actual current depends on board layout and airflow.

Is ZXMN15A27KTC suitable for logic-level gate drive?

No-it is not a logic-level MOSFET. Its typical V_GS(th) is 2.7V, but R_DS(on) is specified at V_GS = 10V (650mΩ). At 3.3V or 5V gate drive, R_DS(on) rises significantly (>2.5Ω), causing excessive conduction loss; a gate driver or level shifter is required for full enhancement.

Does the body diode support continuous reverse conduction?

Yes-the integrated body diode is rated for 5.2A continuous source current (I_S) and 17.2A pulsed (I_SM). Its forward voltage is 0.95V max at 4.3A, making it suitable for freewheeling in buck converters and half-bridge configurations when properly heatsinked.

What is the significance of the "TC" suffix in ZXMN15A27KTC?

The "TC" denotes tape-and-reel packaging: 2,500 units per reel on 16mm-wide carrier tape, compatible with standard SMT pick-and-place equipment. It does not indicate temperature coefficient or variant functionality-the electrical specs match the base ZXMN15A27K part.
