Product details
Overview
DJT4030P from Diodes Incorporated is a low-VCE(SAT) PNP bipolar junction transistor in SOT-223 package, rated for -40 V VCEO, -3 A continuous collector current, and 1.2 W power dissipation on standard FR-4 PCB. It delivers -150 mV VCE(SAT) at IC = -0.5 A / IB = -5 mA and supports medium-power switching in DC-DC converters and industrial motor drivers.
For engineers reviewing the DJT4030P datasheet, DJT4030P pinout, DJT4030P application, or DJT4030P equivalent, key selection criteria include verified VCE(SAT) performance at high IC, thermal resistance (RθJA = 104 °C/W), hFE stability across -55°C to +150°C, and RoHS-compliant matte tin plating suitable for automated reflow assembly.
Technical Context
This PNP transistor operates with fixed-base-controlled saturation switching and exhibits strong hFE consistency: 220 min at IC = -0.5 A, 200–400 at IC = -1 A, and 100 min at IC = -3 A. Its low RCE(SAT) of 167 mΩ enables efficient conduction in high-current load paths.
Switching performance is characterized by 53 ns turn-on time, 180 ns total turn-off time, and 146 ns storage time under VCC = -10 V, IC = -2 A conditions. Input and output capacitances are 150 pF (Cibo) and 35 pF (Cobo) respectively, supporting stable operation up to 150 MHz fT.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -40 V - Maximum allowable voltage between collector and emitter before breakdown in common-emitter configuration. |
| IC (cont.) | -3 A - Continuous DC collector current rating defining safe steady-state switching capacity. |
| VCE(SAT) | -150 mV @ IC = -0.5 A, IB = -5 mA - Confirmed low saturation voltage enabling <0.075 W conduction loss at 0.5 A. |
| hFE | 220 min @ VCE = -1 V, IC = -0.5 A - Minimum DC current gain ensuring reliable base drive margin in linear or saturated operation. |
| RθJA | 104 °C/W - Thermal resistance from junction to ambient on minimal pad layout, defining max power derating above 25°C. |
| fT | 150 MHz - Transition frequency confirming usable bandwidth for medium-speed switching and analog amplification. |
| Package | SOT-223 - Surface-mount package with exposed thermal pad (pin 4) enabling direct PCB heat sinking and 2 W power handling with 1 in² copper. |
Pinout & Package
SOT-223 package with four terminals: pins 1 and 2 are internally connected collectors, pin 3 is emitter, pin 4 is base. The exposed tab (pin 4) serves as the base terminal and provides enhanced thermal conduction to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1,2 (tied) | Collector | Dual-collector configuration lowers series resistance and improves current sharing in high-IC operation. |
| 3 | Emitter | Main current exit path; tied to system ground or low-side return in PNP switch configurations. |
| 4 | Base | Control input; also functions as thermal pad-must be soldered to ≥1 in² copper area for 2 W rating. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(SAT) | -150 mV at 0.5 A enables <75 mW conduction loss, reducing thermal stress in compact power stages. |
| High IC capability | -3 A continuous rating supports direct driving of solenoids, relays, and LED arrays without external buffering. |
| Wide temperature range | -55°C to +150°C operating range ensures reliability in automotive engine compartments and industrial control cabinets. |
| RoHS & "Green" compliant | Lead-free matte tin plating and halogen-free molding compound meet IPC/JEDEC J-STD-020D Level 1 moisture sensitivity. |
Applications
| DC-DC Converter High-Side Switch | Industrial Relay Driver |
|---|---|
Use Scenario: Used as high-side switch in non-synchronous buck converter output stage to regulate 12 V to 5 V at up to 2 A. IC Role / Device Role / Timing Role: PNP transistor configured in emitter-follower mode to source current to load while minimizing dropout voltage. Use Value: -150 mV VCE(SAT) limits dropout to <0.2 V at 1 A, preserving >96% efficiency at full load. | Use Scenario: Drives 24 VDC industrial relay coil (80 Ω, 300 mA) from microcontroller GPIO with open-drain logic interface. IC Role / Device Role / Timing Role: Medium-power PNP switch translating 3.3 V logic-low signal into 24 V sourcing capability. Use Value: hFE ≥200 at 1 A ensures <5 mA base drive requirement, compatible with standard MCU outputs. |
| LED Array Power Switch | Motor Control H-Bridge Complement |
Use Scenario: Supplies switched 24 V power to 12-channel white LED string (each 700 mA) in signage backlight system. IC Role / Device Role / Timing Role: High-current PNP pass element controlled by PWM signal through base resistor network. Use Value: -500 mV VCE(SAT) at -3 A yields only 1.5 W conduction loss, manageable with SOT-223 thermal pad. | Use Scenario: Paired with NPN DJT4031N in complementary emitter-follower H-bridge for 24 V brushed DC motor direction control. IC Role / Device Role / Timing Role: Upper-leg PNP switch providing bidirectional current sourcing/sinking capability. Use Value: Matched VCE(SAT) and switching times (-150 mV / 53 ns) with DJT4031N minimize shoot-through risk during commutation. |
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 |
|---|---|---|---|
| ZXTN25050DFH | Higher VCEO (-50 V), lower VCE(SAT) (-120 mV @ 0.5 A), SOT-23 package (lower power, no thermal pad) | Not suitable for >1 A continuous loads due to 0.5 W PD limit and higher RθJA (200 °C/W) | Select when space-constrained and IC ≤ 0.5 A; avoid for DJT4030P's 3 A use cases. |
| MJD44H11T4G | Higher IC (-8 A), TO-220 package, VCE(SAT) = -1.5 V @ 4 A - significantly higher conduction loss | Requires heatsink for >1 A; incompatible with SMT-only assembly lines | Select only when >3 A peak current required and through-hole mounting acceptable. |
Compared with ZXTN25050DFH and MJD44H11T4G, DJT4030P uniquely balances 3 A current capability, ultra-low VCE(SAT), SMT compatibility, and integrated thermal pad-making it optimal for space-limited, medium-power industrial switching where both efficiency and manufacturability matter.

FAQ
What is the maximum continuous collector current for DJT4030P?
The DJT4030P is rated for -3 A continuous collector current at TA = 25°C with minimum recommended pad layout. Derating is required above 25°C per the 104 °C/W RθJA curve; at 75°C ambient, max IC drops to approximately -2.1 A to maintain TJ ≤ 150°C.
How is the SOT-223 pin 4 used in circuit layout?
Pin 4 is the base terminal and also the exposed thermal pad. It must be soldered directly to a ≥1 in² copper pour to achieve the 2 W power rating and 62.5 °C/W RθJA. Electrically, it connects to the base drive network; thermally, it conducts heat from the die to the PCB plane.
Is DJT4030P suitable for PWM-driven LED dimming?
Yes-its 180 ns turn-off time and 146 ns storage time support PWM frequencies up to 500 kHz without significant duty-cycle distortion. At IC = -2 A, VCE(SAT) remains ≤ -300 mV, limiting switching losses and maintaining thermal stability in constant-current LED strings.
What is the meaning of "ZPS34" marking on the device body?
"ZPS34" is the Diodes Incorporated product type code etched on the top surface of the SOT-223 package. It uniquely identifies the DJT4030P die and process variant, distinct from other PNP transistors in the same package. Date code follows as YWW (e.g., "824" = 2008, week 24).
