Product details

Overview

ZXTP19100CZTA from Diodes Incorporated is a 100V PNP medium-power transistor in SOT89 package, rated for -2A continuous collector current and -100mV V_CE(SAT) at -1A, with <100mΩ equivalent on-resistance and AEC-Q101 qualification for automotive power switching applications.

For engineers reviewing the ZXTP19100CZTA datasheet, ZXTP19100CZTA pinout, ZXTP19100CZTA application, or ZXTP19100CZTA equivalent, key selection criteria include breakdown voltage (BV_CEO = -100V), saturation performance under high-current drive, thermal resistance to lead (R_θJL = 4.7°C/W), and automotive-grade reliability compliance.

Technical Context

This PNP bipolar junction transistor operates in linear or saturated switching modes with guaranteed BV_CEO ≥ -100V and BVECO ≥ -7V, supporting reverse-blocking configurations in high-side load control. Its f_T of 142MHz enables stable operation up to mid-frequency switching.

The device delivers low V_CE(SAT) (-100mV typ. @ -500mA, -100mV typ. @ -1A) due to optimized doping and geometry, while R_θJL = 4.7°C/W ensures efficient heat transfer from junction to PCB copper via the exposed collector pad.

Key Specifications

Parameter	Value and Actual Design Meaning
BV_CEO	-100V minimum - supports 80V DC bus designs with 20% margin against transients
I_C (continuous)	-2A - enables direct driving of solenoids, relays, or LED arrays without external buffering
V_CE(SAT)	-100mV typ. @ -1A - reduces conduction loss to ≤100mW at rated current
R_θJL	4.7°C/W - allows >1.8W steady-state dissipation with 25mm×25mm 1oz Cu PCB
f_T	142MHz - supports clean turn-off in PWM frequencies up to 10MHz
h_FE	200 min. @ -100mA - ensures reliable base drive margin across temperature (-55°C to +150°C)
ESD HBM	4000V - meets IEC 61000-4-2 Level 4 system-level robustness requirements

Pinout & Package

Package: SOT89 - surface-mount plastic package with exposed collector pad for thermal and electrical connection; 0.05g mass; UL 94V-0 rated molding compound.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Emitter)	E	Current source terminal; connects to load return path; requires low-impedance ground reference
Pin 2 (Base)	B	Control input; driven by logic-level or dedicated driver; IB ≤ -1A absolute max
Pin 3 (Collector)	C	Main power terminal; electrically and thermally tied to exposed pad; connects to positive supply rail

Key Features

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP medium-power switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ZXTP2012Z	BV_CEO = -200V, I_C = -1.5A, R_θJA = 125°C/W (SOT23)	Higher voltage rating but lower current and worse thermal performance	Select when >100V blocking is required and board space permits SOT23 footprint
MJD2955T4G	TO-220 package, I_C = -10A, V_CE(SAT) = -1.8V @ -5A	Higher current capability but significantly higher saturation voltage and larger footprint	Select for industrial 120V AC line-switching where thermal mass outweighs efficiency concerns

Compared with ZXTP2012Z and MJD2955T4G, ZXTP19100CZTA uniquely balances 100V blocking, -2A current, ultra-low saturation voltage, and AEC-Q101 qualification in a thermally optimized SOT89 package-making it optimal for space- and efficiency-constrained automotive power stages.

FAQ

What is the maximum safe operating junction temperature for ZXTP19100CZTA?

The absolute maximum junction temperature is +150°C, and the device is characterized across -55°C to +150°C operating range. Derating begins at +25°C ambient, with power dissipation limited to 1.1W on 15mm×15mm 1oz Cu PCB. Thermal resistance to lead (R_θJL = 4.7°C/W) enables higher sustained power when mounted on larger copper areas.

Can ZXTP19100CZTA be used in linear regulator applications?

Yes-it supports linear operation with guaranteed h_FE down to -2A and stable V_BE(ON) (-840mV typ. @ -2A). However, its 1.1W–4.46W power envelope (depending on PCB copper area) and thermal design must be verified per specific dropout voltage and load current to avoid exceeding T_J(max).

Is the SOT89 footprint compatible with automated optical inspection (AOI) systems?

Yes-the SOT89 package has standardized dimensions (4.50mm × 2.50mm × 1.50mm) and clearly defined solder pad layout per Diodes' recommended land pattern. The exposed collector pad provides high-contrast thermal mass for reliable AOI detection of solder joint integrity and coplanarity.

Does ZXTP19100CZTA require a base resistor when driven by a 3.3V microcontroller GPIO?

Yes-a series base resistor is required to limit IB within safe limits. With V_BE(SAT) ≈ -1V and typical h_FE = 200 at -1A, ~5mA base current is needed; a 470Ω resistor ensures ~4.5mA drive from 3.3V GPIO while accounting for voltage drop across the driver output stage.
