Product details
Overview
MJD253-001 from onsemi is a PNP silicon power transistor in DPAK-3 surface-mount package, rated for 100 V VCEO, 4.0 A continuous collector current, and 12.5 W power dissipation at TC = 25 °C. It delivers high DC current gain (hFE = 40–180 at IC = 200 mA), low VCE(sat) (0.3–0.6 V), and 40 MHz fT, designed specifically for low-voltage, low-power audio amplifier stages.
For engineers reviewing the MJD253-001 datasheet, pinout, applications, or equivalent options, this part serves as a complementary PNP counterpart to the NPN MJD243 in Class AB push-pull output stages, requiring verification of base drive capability, thermal derating above 25 °C, and safe operating area compliance under pulsed load conditions.
Technical Context
The MJD253-001 employs annular construction to minimize leakage and supports high-current linear operation with VEB = 7.0 V maximum and IC = 8.0 A peak capability. Its thermal resistance RJC = 10 °C/W enables efficient heat transfer to the PCB copper pad when mounted per FR-4 75 mm², 2 oz. Cu layout.
Electrical behavior is characterized by strong temperature stability: VBE(on) ≤ 1.5 V at IC = 500 mA, VBE(sat) ≤ 1.8 V at IC = 2.0 A, and hFE ≥ 15 even at IC = 1.0 A - enabling predictable biasing in discrete amplifier designs without active compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 100 V - supports rail voltages up to ±48 V in dual-supply audio amplifiers without breakdown risk |
| IC (continuous) | 4.0 A - sufficient for >10 W Class AB output stages into 8 Ω loads with headroom |
| PD @ TC = 25 °C | 12.5 W - requires minimum 75 mm² copper pour (2 oz.) for full-rated conduction |
| hFE | 40–180 @ IC = 200 mA - enables stable DC bias design with minimal emitter degeneration |
| VCE(sat) | 0.3–0.6 V @ IC/IB = 10 - reduces conduction loss and improves efficiency in saturated-switch applications |
| fT | 40 MHz - ensures adequate gain margin for audio bandwidth (20 Hz–20 kHz) with phase stability |
| RJC | 10 °C/W - defines junction-to-case thermal path; mandates direct thermal contact to PCB copper for reliability |
Pinout & Package
DPAK-3 (Case 369C), surface-mount plastic package with exposed drain pad (pin 2 & 4) for thermal conduction and mechanical anchoring. Dimensions: 6.10 × 6.54 × 2.28 mm, pitch 2.29 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input requiring current-limited drive; typical IB ≤ 1.0 A max per datasheet rating |
| 2 | Collector | Main current sink terminal; electrically and thermally connected to exposed metal tab (shared with pin 4) |
| 3 | Emitter | Current source reference node; tied to negative rail in PNP common-emitter configurations |
| 4 | Collector | Second collector connection - parallel path for current and thermal conduction; must be soldered to PCB copper |
Key Features
| Feature | Design Value |
|---|---|
| High DC current gain | hFE ≥ 40 at IC = 200 mA enables simple resistor-biased amplifier topologies without feedback stabilization |
| Low VCE(sat) | 0.3 V min at IC = 500 mA / IB = 50 mA reduces voltage drop and self-heating in linear output stages |
| Annular construction | Minimizes ICBO ≤ 100 nA at 100 V and TJ = 25 °C - critical for low-noise, high-impedance bias networks |
| AEC-Q101 qualified option | NJV prefix variants meet automotive stress testing requirements including temperature cycling and HTRB |
| Pb-free, RoHS-compliant | Meets UL 94 V-0 flammability rating at 0.125 in thickness - suitable for industrial and consumer safety-critical assemblies |
Applications
| Audio Power Amplifier Output Stage | DC Motor Driver Half-Bridge |
|---|---|

Use Value: High hFE (≥15 at IC = 1 A) simplifies base drive design and improves load regulation accuracy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MJD253T4G | Same die, identical electrical specs; differs only in tape-and-reel packaging (2500 pcs/reel vs. rail-packaged MJD253-001) | No functional difference; selected for automated SMT assembly rather than manual or prototyping use | Choose MJD253T4G for volume production; MJD253-001 for evaluation or low-volume builds |
| BD240C | Lower VCEO (80 V), lower fT (3 MHz), TO-126 package - no exposed thermal pad, higher RJA | Suitable for lower-voltage (<24 V) audio or switching apps where thermal performance is less critical | Use BD240C only if board space allows TO-126 and thermal budget permits higher junction rise |
Compared with MJD253-001, MJD253T4G offers identical performance in automated manufacturing contexts, while BD240C trades voltage headroom and RF capability for legacy through-hole compatibility and lower cost - making MJD253-001 optimal for modern SMT-based 100 V-class linear and switching designs requiring thermal efficiency.

FAQ
What is the maximum continuous collector current rating for the MJD253-001?
The MJD253-001 has a maximum continuous collector current (IC) rating of 4.0 A at case temperature TC = 25 °C. This rating assumes proper thermal management using a minimum 75 mm² copper area (2 oz.) on FR-4 PCB. Derating applies above 25 °C at 0.1 W/°C - meaning usable current drops to ~3.0 A at TC = 55 °C. Peak current capability reaches 8.0 A for short pulses.
Does the MJD253-001 support automotive-grade qualification?
The MJD253-001 itself is not automotive-qualified, but onsemi offers the NJVMJD253T4G variant with NJV prefix - fully AEC-Q101 qualified and PPAP capable. That version undergoes additional stress testing including temperature cycling, HTRB, and ESD validation per automotive standards. For non-automotive industrial or consumer use, the standard MJD253-001 meets all electrical and reliability specifications outlined in the datasheet.
What is the pin configuration and thermal pad connection for the MJD253-001?
The MJD253-001 uses DPAK-3 (Case 369C) packaging with four terminals: Pin 1 = Base, Pin 2 = Collector, Pin 3 = Emitter, Pin 4 = Collector. Pins 2 and 4 are internally connected and form an exposed metal thermal pad that must be soldered directly to a large copper pour for effective heat dissipation. The datasheet specifies RJC = 10 °C/W, confirming this pad is the primary thermal path.
How does the MJD253-001 compare to the NPN MJD243 in complementary amplifier designs?
The MJD253-001 is the designated PNP complement to the NPN MJD243, sharing identical voltage (100 V), current (4.0 A), power (12.5 W), and package (DPAK-3) ratings. Their hFE curves and saturation characteristics are balanced to ensure symmetrical conduction in Class AB output stages. Both exhibit matched fT (40 MHz) and thermal resistance, enabling consistent slew rate and thermal tracking - critical for low-distortion audio amplification using the MJD253-001 and MJD243 together.
Is the MJD253-001 RoHS compliant and halogen-free?
Yes, the MJD253-001 is fully RoHS compliant, Pb-free, and halogen-free/BFR-free per onsemi's environmental policy. The "G" suffix in related part numbers (e.g., MJD253T4G) explicitly denotes Pb-free packaging. The epoxy compound meets UL 94 V-0 flammability rating at 0.125 inch thickness, supporting safety certification in end equipment.
