Product details
Overview
ZXTP25100CFHTA from Diodes Incorporated is a 100V PNP medium-power transistor in SOT23 package, designed for high-side switching and gate driving in power conversion circuits. It delivers -1A continuous collector current, -100V VCEO, < -220mV VCE(sat) at -1A, 150mΩ RCE(sat), and operates across -55°C to +150°C. Used in MOSFET/IGBT gate drivers and DC-DC converters.
For engineers reviewing the ZXTP25100CFHTA datasheet, ZXTP25100CFHTA pinout, ZXTP25100CFHTA application, or ZXTP25100CFHTA equivalent, key selection criteria include verified VCE(sat) performance at high IC, thermal resistance under PCB copper coverage conditions, safe operating area limits, and automotive-grade alternatives with AEC-Q101 qualification.
Technical Context
This PNP bipolar junction transistor supports high-voltage reverse blocking (VCBO = -115V) and robust pulsed operation (ICM = -3A). Its fT of 180MHz enables fast switching in gate-drive applications, while hFE ranges from 20–350 across IC = -10mA to -1A, supporting both linear and saturated-mode control.
The device uses a thermally optimized SOT23 package with RθJL = 75.25°C/W and RθJA as low as 69°C/W on 50mm×50mm 2oz Cu PCB. Safe operating area (SOA) is defined up to 100V and 1A DC, with pulse derating validated per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -100V - Ensures reliable high-side switching in 48V and 60V bus systems without breakdown. |
| IC (continuous) | -1A - Supports gate charge delivery for 30A-class MOSFETs at 100kHz+ switching frequencies. |
| VCE(sat) | -150mV to -220mV @ -1A/IB=-100mA - Minimizes conduction loss and self-heating during saturation. |
| RCE(sat) | 150mΩ - Enables precise current-sense compatibility when used in emitter-follower configurations. |
| fT | 180MHz - Allows stable operation in high-speed PWM-driven gate driver stages with minimal phase lag. |

Pinout & Package
Package: SOT23 - Surface-mount plastic package with matte tin terminals, UL 94V-0 rated, 0.008g weight, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current source terminal | Connected to high-voltage rail in high-side driver; carries full load current and defines reference for base drive. |
| 2 (Base) | Control input | Receives negative-turn-on current; requires ≥-100mA drive for full saturation at -1A IC. |
| 3 (Collector) | Output/output return | Connected to gate of driven MOSFET/IGBT; voltage swing limited by VECO = -7V in reverse-blocking mode. |
Key Features
| Feature | Design Value |
|---|---|
| High VCEO rating | -100V enables direct use in 48V telecom and industrial DC-DC primary-side bias rails without level-shifting. |
| Low VCE(sat) | < -220mV @ -1A reduces power dissipation to ≤220mW, easing thermal design on compact PCBs. |
| High peak current capability | ICM = -3A supports short-circuit gate discharge and transient overload handling in motor-driver protection circuits. |
| Automotive-compliant variant available | ZXTP25100CFHQ meets AEC-Q101, enabling drop-in qualification path for automotive gate drivers. |
Applications
| MOSFET Gate Driver | DC-DC Converter Bias Supply |
|---|---|
Use Scenario: Driving N-channel MOSFET gates in synchronous buck controllers where high-side sourcing is required. IC Role / Device Role / Timing Role: PNP emitter-follower providing low-impedance, high-current turn-on path to charge gate capacitance rapidly. Use Value: VCE(sat) ≤ -220mV ensures < 0.22W dissipation at 1A gate peak, reducing thermal stress vs. resistive pull-up solutions. | Use Scenario: Generating isolated auxiliary bias voltage for controller ICs in offline flyback or forward converters. IC Role / Device Role / Timing Role: High-voltage PNP switch regulating Zener-based shunt regulator output under variable load. Use Value: VCBO = -115V allows direct connection to 100V rectified nodes without external clamping diodes. |
| High-Side Load Switch | Motor Phase Driver (Low-Power) |
Use Scenario: Controlling power to sensors or communication modules in battery-powered industrial equipment. IC Role / Device Role / Timing Role: Discrete high-side switch enabling ON/OFF control with reverse-polarity protection via inherent PNP structure. Use Value: RCE(sat) = 150mΩ limits voltage drop to ≤150mV at 1A, preserving >98% supply efficiency at full load. | Use Scenario: Driving gate of half-bridge N-channel MOSFETs in 24V brushed DC motor H-bridge drivers. IC Role / Device Role / Timing Role: Complementary PNP stage delivering fast turn-off current to MOSFET gates during commutation. Use Value: fT = 180MHz supports < 100ns fall time, minimizing shoot-through risk in 50kHz PWM operation. |
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 |
|---|---|---|---|
| ZXTP25020CFHTA | VCEO = -200V, IC = -0.5A, VCE(sat) = -300mV @ -0.5A | Better voltage margin but lower current and higher saturation loss | Select when system bus exceeds 80V and peak IC remains below 500mA. |
| MBT3906DW1T1G | VCEO = -40V, IC = -0.2A, SOT-363 dual package | Lower voltage/current rating; dual configuration saves board space | Prefer for low-power logic-level translation or dual-channel bias generation where 40V rating suffices. |
Compared with ZXTP25100CFHTA, ZXTP25020CFHTA trades current capability for higher voltage headroom, while MBT3906DW1T1G offers integration density at the cost of absolute performance-making the original optimal for 48–60V, 1A gate-drive duty cycles.

FAQ
What is the maximum safe operating voltage for ZXTP25100CFHTA in DC applications?
The ZXTP25100CFHTA has a guaranteed minimum VCEO of -100V and VCBO of -115V. For continuous DC operation, the recommended maximum collector-emitter voltage is -100V to ensure margin against parametric shift and temperature-induced degradation. Operation above this requires verification of SOA curves and thermal derating per Figure 1 in DS33758.
Can ZXTP25100CFHTA be used in automotive applications?
The ZXTP25100CFHTA itself is not AEC-Q101 qualified; however, its automotive-grade counterpart ZXTP25100CFHQ is fully qualified and pin-compatible. For production automotive designs, ZXTP25100CFHQ must be specified-both share identical electrical specs and SOT23 packaging, differing only in test screening and traceability documentation.
How does thermal performance vary between PCB copper configurations?
RθJA ranges from 171°C/W (15mm×15mm 1oz Cu) to 69°C/W (50mm×50mm 2oz Cu). At 1A IC, junction temperature rise varies from ~171°C to ~69°C above ambient-so layout directly determines usable power envelope. Use Figure 2's derating curve to determine max continuous power at target board area and copper weight.
Is the SOT23 footprint compatible with standard reflow profiles?
Yes-the SOT23 package uses matte tin terminations compliant with MIL-STD-202 Method 208 and supports standard lead-free reflow profiles (peak 260°C, 60–90 sec above 217°C). Moisture sensitivity level 1 means no baking is required prior to assembly, simplifying manufacturing flow for high-volume production.
