Diodes Incorporated ZXT13N15DE6TA

Overview

ZXT13N15DE6TA from Diodes Incorporated is a 15V NPN low-saturation switching transistor in SOT26 package, rated for 5A continuous collector current and 15A peak pulse current, with V_CE(sat) ≤ 70 mV at 1 A and R_CE(SAT) = 29 mΩ, deployed in DC–DC converters and motor control power switches.

For engineers reviewing the ZXT13N15DE6TA datasheet, ZXT13N15DE6TA pinout, ZXT13N15DE6TA application, or ZXT13N15DE6TA equivalent, key selection criteria include saturation voltage at high current, AEC-Q101 qualification, thermal resistance (R_θJA = 113 °C/W), and SOT26 lead-free packaging compliance.

Technical Context

This NPN bipolar junction transistor operates as a high-current, low-V_CE(sat) switch in power management circuits, featuring BV_CEO = 15 V, f_T = 72 MHz, and h_FE = 200–900 across 10 mA to 15 A test conditions.

It delivers fast switching performance with t_on = 92 ns and t_off = 340 ns under V_CC = 10 V, I_C = 3 A, and matched base drive, while maintaining robust ESD immunity (HBM = 4 kV) and operating across –55 °C to +150 °C.

FAQ

What is the maximum continuous collector current for ZXT13N15DE6TA?

The maximum continuous collector current is 5 A at T_A = +25 °C with the device mounted on a 25 mm × 25 mm 1 oz copper PCB. Derating applies above +25 °C per the linear derating factor of 8.8 mW/°C, and thermal resistance R_θJA = 113 °C/W governs allowable ambient temperature rise under load.

Is ZXT13N15DE6TA suitable for automotive applications?

Yes - ZXT13N15DE6TA is explicitly qualified to AEC-Q101 standards, with full test reports covering temperature cycling, high-temperature operating life, ESD (HBM = 4 kV), and mechanical robustness. Its –55 °C to +150 °C operating range and green RoHS-compliant construction meet automotive Tier-1 requirements.

How does the dual-terminal SOT26 configuration affect thermal performance?

The SOT26 package integrates two collectors, two emitters, and two bases internally paralleled to reduce effective R_CE(SAT) and distribute thermal load. Measured R_θJL = 18.6 °C/W confirms improved junction-to-lead heat transfer versus standard SOT23, enabling higher sustained current on thermally constrained PCBs.

Can ZXT13N15DE6TA replace a MOSFET in low-voltage switching applications?

Yes - it serves as a drop-in alternative where gate drive complexity or cost is prohibitive. With V_CE(sat) ≤ 70 mV at 1 A and h_FE ≥ 300, it achieves comparable conduction loss to many 20–30 mΩ MOSFETs when driven with ~100 mA base current, though switching speed (t_off = 340 ns) is slower than typical logic-level MOSFETs.
