Product details
Overview
DPLS350E-13 from Diodes Incorporated is a low VCE(SAT) PNP bipolar junction transistor in SOT-223 package, rated for −50 V VCEO, −3 A continuous collector current, and 1 W power dissipation at TA = 25°C. It serves as a medium-power switching or linear amplification device in DC-DC converters, relay drivers, and load-switching circuits.
For engineers reviewing the DPLS350E-13 datasheet, DPLS350E-13 pinout, DPLS350E-13 application, or DPLS350E-13 equivalent, key selection criteria include verified VCE(SAT) ≤ −300 mV at −2 A/−200 mA drive, hFE ≥ 100 up to −2 A, and thermal resistance RθJA = 125 °C/W on FR-4 PCB.
Technical Context
This PNP transistor uses epitaxial planar die construction for stable gain and low leakage. Its −50 V VCEO and −60 V VCBO support robust blocking in industrial supply rails, while its −100 nA ICBO at 25°C and −50 μA at 150°C ensures reliable cutoff over temperature.
The device delivers hFE = 200 at −0.5 A and −1 A (VCE = −2 V), dropping to 100 at −2 A - enabling predictable current gain across its operating range. Its fT = 100 MHz supports moderate-speed switching applications such as PWM-controlled power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage before breakdown in common-emitter configuration. |
| IC (cont.) | −3 A: Continuous DC collector current rating under specified thermal conditions. |
| VCE(SAT) | −300 mV max at IC = −2 A, IB = −200 mA: Enables low conduction loss in high-current switching paths. |
| hFE | 100 min at IC = −2 A, VCE = −2 V: Ensures sufficient current gain for base-drive efficiency at full load. |
| RθJA | 125 °C/W: Junction-to-ambient thermal resistance on standard FR-4 PCB per AP02001 layout - defines heatsinking requirements. |
| fT | 100 MHz: Transition frequency at VCE = −5 V, IC = −100 mA - supports switching up to ~10–15 MHz practical duty-cycle operation. |
| PD | 1 W at TA = 25°C: Maximum allowable power dissipation with adequate board copper area and airflow. |
Pinout & Package
Package: SOT-223 surface-mount plastic package with exposed collector tab (pins 1 and 2 are collectors, pin 3 is base, pin 4 is emitter). UL 94V-0 rated, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | Collector (C) | Electrically connected internally; used for high-current output path and thermal conduction to PCB copper pour. |
| 3 | Base (B) | Control terminal requiring −200 mA drive for full saturation at −2 A collector current. |
| 4 | Emitter (E) | Reference node for biasing; connects to system ground or positive rail depending on PNP topology. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(SAT) | ≤ −300 mV at −2 A enables <1 W conduction loss in 12 V load-switching applications. |
| High hFE stability | 200 min at −0.5 A and −1 A ensures consistent base drive sizing across partial-load conditions. |
| SOT-223 thermal performance | Exposed collector pad allows direct thermal coupling to PCB plane - critical for sustained −2 A operation. |
| RoHS & "Green" compliance | Matte tin-plated leadframe and halogen-free molding compound meet global environmental directives. |
| Moisture sensitivity level | Level 1 per J-STD-020D: No bake required prior to reflow - simplifies automated assembly. |
Applications
| DC-DC Converter Switch | Industrial Relay Driver |
|---|---|
Use Scenario: High-side switch in non-synchronous buck converter output stage driving 12 V/2 A loads. IC Role / Device Role / Timing Role: PNP pass transistor controlling energy transfer during off-time; operates in saturation and cutoff. Use Value: −300 mV VCE(SAT) limits conduction loss to ≤600 mW at 2 A, reducing thermal stress on PCB layout. | Use Scenario: Driving 24 VDC coil of industrial control relay with microcontroller GPIO. IC Role / Device Role / Timing Role: Medium-power interface switch translating logic-level signals to higher-voltage/current actuation. Use Value: hFE ≥ 100 at −2 A allows 20 mA base drive to fully saturate - compatible with standard MCU outputs. |
| Load Switch for 5 V Systems | Linear Regulator Pass Element |
Use Scenario: Power sequencing switch enabling/disabling downstream 5 V subsystems in embedded controllers. IC Role / Device Role / Timing Role: High-side load switch controlled by enable signal; requires fast turn-on/turn-off with minimal shoot-through risk. Use Value: −180 mV VCE(SAT) at −1 A yields only 180 mW dissipation - avoids need for heatsink in compact designs. | Use Scenario: Pass element in adjustable negative LDO regulator supplying −5 V to analog circuitry. IC Role / Device Role / Timing Role: Linear regulating transistor dissipating excess voltage as heat; biased in active region. Use Value: RCE(SAT) = 67 mΩ typ enables precise dropout control and stable regulation under 1 A load variation. |
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 |
|---|---|---|---|
| ZTX951 | VCEO = −60 V, IC = −3 A, VCE(SAT) = −400 mV @ −2 A - higher saturation voltage. | Same SOT-223 footprint but lower gain consistency above −1 A (hFE drops to 60). | Prefer where higher breakdown margin is needed and higher VCE(SAT) is acceptable. |
| MJD2955T4G | VCEO = −60 V, IC = −10 A, VCE(SAT) = −1.8 V @ −5 A - much higher saturation voltage, TO-220 package. | Requires heatsink and through-hole assembly; unsuitable for space-constrained SMT designs. | Choose only when >3 A current capability and higher voltage margin are mandatory. |
Compared with ZTX951 and MJD2955T4G, DPLS350E-13 offers superior VCE(SAT) performance and SMT compatibility for 2–3 A switching, while maintaining tighter hFE control and lower thermal resistance than TO-220 alternatives.

FAQ
What is the maximum safe operating temperature for DPLS350E-13?
The DPLS350E-13 has an operating junction temperature range of −55°C to +150°C. At ambient temperatures above 25°C, derating applies: power dissipation decreases linearly to zero at +125°C per Figure 1 in DS31230. Thermal design must ensure TJ stays within this limit using appropriate PCB copper area.
Is DPLS350E-13 pin-compatible with other SOT-223 PNP transistors?
Yes - DPLS350E-13 follows standard SOT-223 pinout: pins 1 & 2 = collector, pin 3 = base, pin 4 = emitter. This matches industry-standard PNP SOT-223 devices like ZTX951 and NSS20201MR6T1, enabling drop-in replacement where electrical specs align.
Does DPLS350E-13 require special PCB layout considerations?
Yes - the exposed collector pad (pins 1 & 2) must be connected to a minimum 100 mm² copper pour for thermal management. Diodes recommends following AP02001 pad layout (6.5 × 3.5 mm outline, 2.3 mm center pad spacing) to achieve rated RθJA = 125 °C/W.
Can DPLS350E-13 be used in linear amplifier configurations?
Yes - its hFE stability (200 min at −0.5 A), low leakage (−100 nA ICBO), and fT = 100 MHz support Class-A or AB audio and signal amplification up to ~1 MHz. Biasing must maintain VCE > −2 V and avoid exceeding PD = 1 W under quiescent conditions.
