Product details

Overview

ZXTP5401FLTA from Diodes Incorporated is a 150V PNP silicon planar high-voltage transistor in SOT23 package, rated for -600mA continuous collector current, -150V V_CEO, and 310mW power dissipation at T_A = 25°C; used in high-side switching, voltage regulation, and industrial power control circuits where high breakdown voltage and low saturation voltage are required.

For engineers reviewing the ZXTP5401FLTA datasheet, ZXTP5401FLTA pinout, ZXTP5401FLTA application, or ZXTP5401FLTA equivalent, key selection criteria include verified V_CEO ≥ -150V, h_FE ≥ 50 at I_C = -1mA, V_CE(sat) ≤ -200mV at I_C = -50mA/I_B = -5mA, thermal resistance R_θJA = 403°C/W on minimum pad layout, and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This PNP bipolar junction transistor operates with emitter-grounded configuration and supports high-voltage blocking up to -160V V_CBO. Its h_FE remains stable across I_C = -1mA to -50mA (50–135), enabling predictable gain in linear and switching modes.

V_CE(sat) is specified at -70mV (typ.) for I_C = -10mA/I_B = -1mA and -500mV (max.) for I_C = -50mA/I_B = -5mA, confirming low conduction loss in saturated switching applications. Transition frequency f_T = 100MHz supports moderate-speed switching up to ~100kHz duty-cycle operation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	-150V - Enables use in 100V+ DC bus switching without avalanche stress
I_C (cont.)	-600mA - Supports load currents up to 600mA in high-side driver stages
P_D	310mW - Limits usable power in SOT23 without forced cooling or large copper pour
h_FE	50–135 - Ensures reliable base drive design across operating range
V_CE(sat)	-500mV max @ I_C=-50mA - Minimizes conduction loss in saturated switch mode
f_T	100MHz - Allows stable operation in PWM control up to ~100kHz
R_θJA	403°C/W - Requires careful PCB thermal layout for >150°C junction temperature margin

Pinout & Package

Package: SOT23 - Surface-mount plastic case, 0.008g weight, UL 94V-0 rated, moisture sensitivity level 1, matte tin terminals solderable per MIL-STD-202 Method 208.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP high-voltage switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ZXTP5402FLTA	V_CEO = -200V, I_C = -500mA, P_D = 300mW	Higher voltage margin but lower current capability	Select when system transients exceed -150V but load current ≤ 500mA
MMDT5401-7-F	V_CEO = -150V, I_C = -600mA, R_θJA = 357°C/W (larger pad)	Same electrical specs, improved thermal performance on 15mm×15mm PCB	Select when board space allows larger thermal pad and ambient >70°C

Compared with ZXTP5401FLTA, ZXTP5402FLTA trades current capacity for higher voltage robustness, while MMDT5401-7-F delivers identical electrical ratings with better thermal management-making it preferable for thermally constrained designs requiring full 600mA operation.

FAQ

What is the maximum safe operating voltage for ZXTP5401FLTA in continuous DC applications?

The absolute maximum collector-emitter voltage is -150V (V_CEO) at T_A = 25°C. For reliable long-term operation, derate to ≤ -120V under worst-case ambient and thermal conditions. Transient spikes must not exceed -160V (V_CBO) even momentarily, as no built-in avalanche energy rating is specified.

Can ZXTP5401FLTA be used as a direct replacement for ZXTN5551FL in complementary pair designs?

No-ZXTP5401FLTA is PNP while ZXTN5551FL is NPN; they are complementary types, not drop-in replacements. Their pinouts match (E-B-C), but polarity reversal requires redesign of base drive and load connections. Both share SOT23 packaging and similar voltage/current ratings, enabling matched-pair implementation in push-pull or H-bridge topologies.

Does ZXTP5401FLTA require a heatsink in standard SOT23 mounting?

No external heatsink is required, but thermal performance depends entirely on PCB layout. On minimum recommended FR4 pad (1oz copper), R_θJA = 403°C/W limits continuous power to ~150mW at 70°C ambient. Use enlarged copper pours or thermal vias if dissipating >100mW continuously to maintain T_J < 125°C.

Is ZXTP5401FLTA suitable for PWM motor control at 20kHz?

Yes-its f_T = 100MHz and documented switching times (t_d = 386ns, t_r = 202ns, t_s = 1720ns, t_f = 275ns) support clean 20kHz PWM operation with minimal overlap loss. Ensure base drive provides sufficient reverse recovery current to minimize storage time effects in inductive loads.
