Product details

Overview

ZXTP2014ZTA from Diodes Incorporated is a PNP high-voltage bipolar junction transistor in SOT89 package, rated for -140V V_CEO, -3A continuous collector current, and -75mV V_CE(sat) at -0.5A. It delivers low on-resistance (R_sat = 85mΩ) and supports high-side switching in industrial line-switching and motor-driving circuits.

For engineers reviewing the ZXTP2014ZTA datasheet, ZXTP2014ZTA pinout, ZXTP2014ZTA application, or ZXTP2014ZTA equivalent, key selection criteria include verified high-voltage blocking (-140V), pulsed switching capability (t_on = 42ns, t_off = 636ns), thermal resistance (R_θJA = 60°C/W on 50mm² copper), and automotive-grade variant availability (ZXTP2014ZQ).

Technical Context

This PNP transistor operates with emitter-grounded configuration and supports linear and switching modes. Its BV_CEO of -140V and BV_CBO of -180V enable robust high-side switch operation in 100–120V DC bus systems, while f_T = 120MHz confirms suitability for medium-frequency switching up to ~10MHz.

The device exhibits h_FE = 100–300 across IC = -10mA to -3A, enabling stable current gain in both analog amplification and saturated-switching applications. Low V_BE(sat) (-970mV at -3A) and tight V_CE(sat) distribution (-37mV to -75mV) ensure predictable drive requirements and minimal conduction loss under load.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	-140V - Maximum safe collector-emitter voltage in open-base condition; enables use in 100V+ DC line-switching
I_C (cont.)	-3A - Continuous collector current rating; supports motor drivers and SLIC loads without forced cooling
V_CE(sat)	-75mV @ -0.5A - Low saturation voltage ensures <37.5mW conduction loss at mid-load current
R_sat	85mΩ - Equivalent on-resistance derived from V_CE(sat)/I_C; simplifies thermal modeling in power stages
f_T	120MHz - Transition frequency confirms usable bandwidth for pulse-width modulation up to ~10MHz
R_θJA	60°C/W - Thermal resistance on 50mm² copper; allows ~2.1W dissipation before exceeding 150°C junction limit
t_off	636ns - Measured turn-off time at -1A, -50V; defines minimum dead-time in complementary high-side driver designs

Pinout & Package

Package: SOT89 - Surface-mount plastic package with integrated heat slug (pin 2 connected to tab), rated for 2.1W power dissipation on 50mm² copper, UL 94V-0 compliant, moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current source terminal	Connected to positive rail in high-side switch; carries full load current and sets reference for base drive
2 (Collector)	Current sink terminal	Connected to load; voltage swing limited to -140V max; thermally coupled to package tab
3 (Base)	Control input	Receives negative current to saturate; requires -300mA for full -3A conduction per h_FE and V_BE(sat) specs

Key Features

Feature	Design Value
High-voltage blocking	BV_CEO = -140V enables direct interface with 100–120V DC industrial buses without external snubbers
Low saturation loss	V_CE(sat) ≤ -75mV at -0.5A reduces conduction loss to <37.5mW, easing thermal design in compact enclosures
Thermally enhanced package	SOT89 tab-connected collector provides R_θJC = 18.5°C/W, supporting 2.1W dissipation with minimal heatsinking
Automotive-qualified variant	ZXTP2014ZQ meets AEC-Q101; same electrical specs but qualified for under-hood temperature cycling and vibration

Applications

Motor Drive Stage

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
ZXTP2029ZTA	V_CEO = -200V, I_C = -2A, V_CE(sat) = -100mV @ -0.5A	Higher voltage margin but lower current rating and higher saturation loss	Select when system transients exceed -140V but load current remains ≤2A
MMBT6427LT1G	V_CEO = -100V, I_C = -1A, SOT23 package, R_θJA = 277°C/W	Lower voltage/current ratings and significantly worse thermal performance	Only suitable for low-power, non-continuous duty-cycle applications where board space is critical

Compared with ZXTP2014ZTA, ZXTP2029ZTA trades current capacity and conduction efficiency for higher voltage headroom, while MMBT6427LT1G sacrifices both voltage and thermal capability for ultra-compact packaging-making ZXTP2014ZTA the optimal balance for 100V-class industrial switching with sustained 3A loads.

FAQ

What is the maximum allowable junction temperature for ZXTP2014ZTA?

The absolute maximum operating junction temperature is +150°C, as specified in the Absolute Maximum Ratings table. This limit applies under steady-state conditions with proper PCB thermal design-specifically, a 50mm × 50mm single-sided 1oz copper pad per Note 6. Exceeding this temperature risks permanent degradation of h_FE and increased leakage current.

Can ZXTP2014ZTA be used in avalanche mode?

No-ZXTP2014ZTA is not rated or characterized for controlled avalanche operation. Its Safe Operating Area (SOA) curve in Figure 1 shows only forward-biased second-breakdown limits, and no avalanche energy (E_AS) or ruggedness data is provided. For avalanche-tolerant designs, Diodes recommends dedicated avalanche-rated transistors such as the ZXTN2012F.

Is the SOT89 package lead-free and RoHS-compliant?

Yes-ZXTP2014ZTA is fully lead-free and RoHS 3 compliant (2015/863/EU), with matte tin-plated leads solderable per MIL-STD-202, Method 208. It is also halogen- and antimony-free ("Green"), containing <900ppm bromine, <900ppm chlorine, and <1000ppm antimony compounds per Diodes' definition.

How does the automotive-grade ZXTP2014ZQ differ electrically from ZXTP2014ZTA?

ZXTP2014ZQ shares identical electrical specifications-including V_CEO, I_C, V_CE(sat), h_FE, and thermal parameters-with ZXTP2014ZTA. The difference lies solely in qualification: ZXTP2014ZQ undergoes AEC-Q101 stress testing (temperature cycling, HTRB, uHAST) and is manufactured in an IATF 16949-certified facility, ensuring reliability for automotive under-hood applications.
