Product details
Overview
ZXTP25100CFHQTA from Diodes Incorporated is a 100V PNP medium-power bipolar junction transistor (BJT) in SOT23 package, rated for -1A continuous collector current, -100V VCEO, and -220mV VCE(SAT) at -1A. It delivers 150mΩ RCE(SAT), supports 7V reverse blocking, and is AEC-Q101 qualified for automotive gate driving and motor control applications.
For engineers reviewing the ZXTP25100CFHQTA datasheet, ZXTP25100CFHQTA pinout, ZXTP25100CFHQTA application, or ZXTP25100CFHQTA equivalent, this device serves as a high-reliability, lead-free PNP switch optimized for high-side driver circuits, DC–DC converters, and IGBT/MOSFET gate drive stages where low saturation voltage and robust breakdown margins are critical.
Technical Context
This PNP BJT operates with a minimum hFE of 200 at -10mA and maintains usable gain down to -1A (hFE ≥ 20), enabling stable current amplification across wide load ranges. Its -115V VCBO and -7V VECO support operation in high-voltage bias networks and reverse-polarity protection schemes.
The device exhibits fast switching performance with tD = 15.8ns, tR = 41ns, tS = 411ns, and tF = 89ns under pulsed conditions (VCC = -10V, IC = -500mA), making it suitable for medium-frequency power control up to ~1 MHz. Its fT of 180MHz confirms high-frequency capability despite being a medium-power discrete.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -100V - Enables use in 48V and 60V automotive systems with margin against transients. |
| IC (continuous) | -1A - Supports medium-power switching loads such as small motors or gate drivers without heatsinking. |
| VCE(SAT) | -140mV to -220mV @ -1A - Minimizes conduction loss and self-heating in high-duty-cycle operation. |
| RCE(SAT) | 150mΩ - Directly determines on-state power dissipation (P = I²R) at full load. |
| fT | 180MHz - Validates suitability for fast-switching applications like synchronous rectification or PWM gate drive. |
| hFE | 20–500 - Wide gain range allows flexible base drive design across operating currents from mA to 1A. |
| TJ range | -55°C to +150°C - Qualified for under-hood automotive environments and industrial temperature cycling. |
Pinout & Package
Package: SOT23 - Surface-mount plastic package measuring 2.40mm × 1.30mm × 1.00mm (L × W × H), UL 94V-0 rated, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current source terminal for PNP operation | Connected to higher potential rail; must sustain -7V reverse bias and handle full load current. |
| 2 (Base) | Control input for minority-carrier injection | Requires precise current-limited drive (-500mA max); sensitive to ESD due to thin oxide layer. |
| 3 (Collector) | Current sink terminal | Connected to load/ground side; withstands -115V VCBO and dissipates majority of switching/conduction loss. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical shock testing. |
| 150mΩ RCE(SAT) | Reduces on-state power loss to ≤150mW at 1A, easing thermal management in compact PCB layouts. |
| 7V reverse emitter-collector blocking | Enables safe operation in bidirectional or flyback configurations where reverse voltage may appear across E-C. |
| Lead-free & halogen-free | Complies with RoHS 3 and JEDEC J-STD-020 Level 1, eliminating solder joint corrosion and enabling green manufacturing. |
Applications
| Motor Drive | DC–DC Converter |
|---|---|
Use Scenario: Driving brushed DC motors in automotive HVAC actuators and seat positioners. IC Role / Device Role / Timing Role: High-side PNP switch controlling motor direction and speed via PWM. Use Value: -100V rating accommodates battery transients; low VCE(SAT) reduces heat generation during 100% duty cycle stall conditions. |
Use Scenario: Synchronous rectification in non-isolated buck converters for ADAS camera modules. IC Role / Device Role / Timing Role: Low-loss PNP switch replacing Schottky diode in high-efficiency step-down regulation. Use Value: 150mΩ RCE(SAT) cuts conduction loss by >40% vs. typical 0.4V Schottky, improving efficiency at 1A output. |
| MOSFET Gate Driver | High-Side Driver |
Use Scenario: Active pull-down stage in dual-NMOS half-bridge gate drivers for BLDC inverters. IC Role / Device Role / Timing Role: Fast-turn-off PNP switch discharging NMOS gate capacitance rapidly. Use Value: 89ns fall time ensures <100ns gate discharge, supporting >100kHz PWM without shoot-through risk. |
Use Scenario: Level-shifted high-side switch in automotive LED headlamp current regulators. IC Role / Device Role / Timing Role: PNP-based current source delivering stable 350mA to LED string with reverse polarity protection. Use Value: -7V VECO blocks reverse battery connection; AEC-Q101 qualification ensures field longevity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP medium-power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTP25020CFH | Lower VCEO (-20V), higher hFE (min 300 @ -500mA), same SOT23 package | Better suited for 12V logic-level gate drive; insufficient for 48V+ bus monitoring or transient clamping | Select when system voltage ≤24V and gain stability at low current is prioritized over breakdown margin. |
| MBT3906DW1T1G | Lower IC (-200mA), lower VCEO (-40V), higher VCE(SAT) (-400mV @ -100mA), SOT363 package | Designed for signal-level switching only; not rated for 1A loads or automotive PPAP | Use only in low-power bias networks or logic inversion-avoid in power switching or AEC-Q101–required designs. |
Compared with ZXTP25100CFHQTA, ZXTP25020CFH trades off voltage ruggedness for higher gain at low current, while MBT3906DW1T1G lacks both current capacity and automotive qualification-making ZXTP25100CFHQTA the sole choice for 1A, 100V, AEC-Q101–compliant high-side switching.

FAQ
What is the maximum allowable base current for ZXTP25100CFHQTA?
The absolute maximum base current is -500mA, per the Absolute Maximum Ratings table. However, for reliable operation at IC = -1A, the recommended base drive is -100mA (IC/IB = 10), ensuring saturation while avoiding excessive base power dissipation and thermal stress on the bond wires.
Does ZXTP25100CFHQTA support reverse-battery protection?
Yes-it provides -7V reverse emitter-collector blocking (VECO), allowing it to withstand reverse polarity events common in automotive 12V systems. This enables use in simple reverse-voltage protection circuits without additional diodes, though external TVS clamping is still recommended for >7V transients.
Can ZXTP25100CFHQTA be used in parallel for higher current handling?
No-BJTs exhibit negative temperature coefficient of VBE, causing current hogging when paralleled without individual emitter resistors. The datasheet does not specify matched hFE or VBE tracking, and thermal coupling in SOT23 packages makes forced current sharing impractical. Use a single higher-current device instead.
What is the thermal resistance from junction to ambient under standard PCB conditions?
RθJA is 171°C/W when mounted on a 15mm × 15mm × 1.6mm FR-4 PCB with 1oz copper (Note 6). With 2oz copper on 25mm × 25mm board (Note 7), it improves to 119°C/W-enabling 0.73W power dissipation at ≤85°C ambient without forced airflow.
