Product details
Overview
ZXTP25100CZTA from Diodes Incorporated is a 100V PNP medium-power transistor in SOT89 package, rated for -1A continuous collector current, -100V VCEO, and VCE(SAT) < -225mV @ -1A. It delivers low on-resistance (RCE(SAT) = 155mΩ) and meets AEC-Q101 for automotive reliability, used in high-voltage load switching and industrial power control circuits.
For engineers reviewing the ZXTP25100CZTA datasheet, ZXTP25100CZTA pinout, ZXTP25100CZTA application, or ZXTP25100CZTA equivalent, key selection criteria include verified VCEO ≥ -100V, confirmed SOT89 thermal performance with RθJA = 28°C/W (50mm×50mm 2oz Cu), and complementary pairing with ZXTN25100DZ for push-pull designs.
Technical Context
This PNP bipolar junction transistor operates in linear and saturated switching modes with guaranteed BVCEO = -100V and BVECO = -7V, enabling reverse-blocking capability in emitter-follower or high-side switch configurations. Its fT = 180MHz supports fast switching up to ~100kHz with controlled tF = 89ns and tS = 411ns.
Thermal design is defined by three mounting-dependent RθJA values (117°C/W to 28°C/W) and RθJL = 7.95°C/W to the exposed collector pad - critical for PCB copper area planning. ESD robustness includes HBM = 4kV and MM = 400V per JEDEC JESD22-A114/A115.
Key Specifications

|---|---|
| VCEO | -100V - Ensures safe operation in 48V–72V industrial bus systems with margin against transients. |
| IC (cont.) | -1A - Supports sustained load currents in DC-DC pre-regulators and motor gate drivers. |
| VCE(SAT) | < -225mV @ -1A - Minimizes conduction loss (≤225mW) in high-duty-cycle switching. |
| RCE(SAT) | 155mΩ - Enables direct replacement of discrete PNP+resistor combos in compact layouts. |
| fT | 180MHz - Validates use in high-speed PWM feedback paths and active clamp circuits. |

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 |
|---|---|---|---|
| ZXTP2012ZTA | VCEO = -100V same, but IC = -1.25A and VCE(SAT) = -200mV @ -1A; SOT223 package (larger footprint, higher RθJA = 60°C/W). | Better current handling but requires PCB redesign; unsuitable for space-constrained SOT89 layouts. | Select when higher peak current (1.25A) is required and thermal budget allows larger package. |
| MMDT2907A-7-F | VCEO = -60V only; IC = -600mA; no AEC-Q101 qualification; SOT363 package (dual device, lower power density). | Limited to 24V systems; lacks automotive qualification and thermal performance for 48V+ applications. | Acceptable only for non-automotive, low-voltage consumer designs where cost outweighs reliability. |
Compared with ZXTP25100CZTA, ZXTP2012ZTA trades SOT89 compatibility for higher current and worse thermal resistance, while MMDT2907A-7-F sacrifices voltage rating, automotive compliance, and single-device simplicity - making ZXTP25100CZTA optimal for AEC-Q101-compliant 48V–72V high-side switching.

FAQ
What is the maximum allowable junction temperature for ZXTP25100CZTA?
The absolute maximum junction temperature is +150°C, with continuous operation permitted from -55°C to +150°C. Derating begins at +25°C ambient using RθJA = 28°C/W (50mm×50mm 2oz Cu), allowing 4.46W max power dissipation at 25°C ambient, decreasing linearly to zero at 150°C.
Can ZXTP25100CZTA be used in linear amplifier applications?
Yes - its hFE = 200–500 across -10mA to -1A and fT = 180MHz support Class-A and AB audio pre-amplifier stages. However, thermal design must account for RθJA = 28°C/W and ensure junction temperature remains below 150°C under quiescent bias conditions.
Is the exposed collector pad electrically connected to any internal node?
Yes - the exposed collector pad is directly bonded to the transistor's collector terminal. It must be soldered to a dedicated PCB copper pour tied to the collector net; floating or grounded pads will cause functional failure and thermal derating.
Does ZXTP25100CZTA require a base resistor when driven by a microcontroller GPIO?
Yes - a series base resistor is mandatory to limit IB to ≤ -500mA (absolute max). For -1A collector current with hFE ≈ 200, a 10kΩ resistor suffices with 3.3V GPIO; for faster switching, reduce to 1kΩ to deliver -100mA base drive, ensuring VCE(SAT) < -225mV.
