Product details

Overview

ZXTP2008ZTA from Diodes Incorporated is a 30V PNP medium-power transistor optimized for high-current switching in power conversion and gate drive circuits, featuring -5.5A continuous collector current, < -60mV V_CE(SAT) at -1A, 24mΩ equivalent on-resistance at -5.5A, and AEC-Q101 qualification for automotive-grade reliability - deployed in DC-DC converters and MOSFET gate drivers.

For engineers reviewing the ZXTP2008ZTA datasheet, ZXTP2008ZTA pinout, ZXTP2008ZTA application, or ZXTP2008ZTA equivalent, key selection criteria include saturation voltage linearity down to -10mA, h_FE specified up to -20A, thermal resistance of 60°C/W (50mm×50mm copper), and SOT89 package compatibility with high-power PCB layouts.

Technical Context

This PNP bipolar junction transistor delivers low-saturation switching performance with V_CE(SAT) ≤ -55mV at -5.5A/IB = -500mA and maintains gain linearity across three decades of collector current (-10mA to -20A). Its rugged construction includes -50V V_CBO, -30V V_CEO, and 4kV HBM ESD rating.

The device operates across -55°C to +150°C, supports pulsed peak currents up to -20A, and achieves 110MHz f_T at -10V V_CE/ -100mA I_C, enabling fast switching in motor control and charging circuits where precise base-driven turn-on/turn-off timing is required.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	-30V - maximum safe collector-emitter voltage under DC operation
I_C (cont.)	-5.5A - continuous current handling capacity without thermal derating on 50mm×50mm copper
V_CE(SAT)	< -55mV @ -5.5A/IB = -500mA - enables < 0.3W conduction loss in high-current switches
R_SAT	24mΩ @ -5.5A - low equivalent on-resistance reduces I²R heating in power stages
h_FE	70–200 @ -5A to -20A - stable current gain ensures predictable base drive sizing
f_T	110MHz - supports switching frequencies up to ~10MHz in optimized gate-drive applications
R_θJA	60°C/W (50mm×50mm Cu) - defines thermal margin for sustained 1.5W dissipation at +100°C ambient

Pinout & Package

Package: SOT89 - surface-mount plastic package with exposed collector tab for thermal enhancement; 0.05g mass; UL 94V-0 rated molding compound; matte tin-plated leads.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Emitter)	Current source terminal	Connected to higher potential rail; carries full load current in high-side switch configuration
Pin 2 (Base)	Control input	Receives negative bias current to saturate transistor; requires ≥ -500mA drive for full -5.5A conduction
Pin 3 (Collector)	Power output / heat sink node	Internally connected to exposed metal tab; must be soldered to ≥25mm² copper for R_θJA = 60°C/W

Key Features

Feature	Design Value
Low V_CE(SAT) at high current	< -55mV @ -5.5A enables < 0.3W conduction loss in 12V/5A power switches
AEC-Q101 qualification	Validated for automotive temperature cycling, humidity, and mechanical shock per stress test requirements
Gain linearity down to -10mA	Supports accurate analog current sensing and linear regulation modes without gain collapse
High h_FE hold-up to -20A	Maintains minimum h_FE = 10 at -20A pulse, ensuring reliable saturation during transient overloads
Green RoHS-compliant construction	Halogen- and antimony-free mold compound (<900ppm Br+Cl, <1000ppm Sb) meets automotive environmental standards

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
ZXTN2008ZTA	NPN complement with identical SOT89 package, same V_CEO/I_C, but +5.5A rating and +60mV V_CE(SAT)	Used in low-side switching; not interchangeable without circuit topology change	Select when NPN topology is preferred or complementary pairing required in push-pull stages
MJD2955T4G	TO-220 package, -10A I_C, -70V V_CEO, higher V_CE(SAT) (-1.1V @ -5A), no AEC-Q101 qualification	Higher power, non-automotive, heatsink-mounted applications only	Choose for legacy designs needing higher voltage margin and discrete heatsinking, not space-constrained SMT layouts

Compared with ZXTN2008ZTA and MJD2955T4G, ZXTP2008ZTA uniquely balances automotive qualification, SOT89 footprint, sub-60mV saturation, and gain stability across wide current range - making it optimal for compact, high-reliability DC-DC and gate-drive modules.

FAQ

What is the maximum allowable junction temperature for ZXTP2008ZTA?

The absolute maximum operating junction temperature is +150°C, verified per JEDEC JESD22-A104. This limit applies under steady-state conditions with proper PCB copper area (50mm×50mm 1oz Cu) and still-air ambient. Derating begins above +25°C ambient at 16.8mW/°C for that layout.

Can ZXTP2008ZTA replace older PNP transistors like MPSA92 in gate driver circuits?

No - MPSA92 is a general-purpose PNP with only -500mA I_C and -300V V_CEO; ZXTP2008ZTA provides -5.5A I_C and -30V V_CEO with far lower saturation voltage. Direct replacement would cause catastrophic failure due to excessive current demand and insufficient voltage rating mismatch.

Is the SOT89 package lead finish compatible with lead-free reflow profiles?

Yes - the matte tin-plated leads meet IPC-J-STD-020 moisture sensitivity level 1 and are qualified for standard Pb-free reflow profiles (peak 260°C, 60s max above 217°C), with no pre-bake required per J-STD-020.

Does ZXTP2008ZTA require a base resistor in all applications?

Yes - base current must be limited to prevent damage; typical design uses 10–100Ω series resistor depending on drive voltage and required I_B (e.g., -500mA for -5.5A I_C). The device lacks integrated base resistors and is not a digital transistor.
