Product details

Overview

MJD32CRLG from onsemi is a PNP complementary power transistor in DPAK (TO-252) surface-mount package, rated for 100 V_CEO, 3 A continuous collector current, and 15 W total power dissipation at T_C = 25 °C. It serves as a general-purpose amplifier and low-speed switching device in industrial power supplies, motor drivers, and relay drivers where robust thermal performance and AEC-Q101-compliant reliability are required.

For engineers reviewing the MJD32CRLG datasheet, pinout, applications, or equivalent options, key selection criteria include its 100 V blocking capability, 1.2 V_CE(sat) at I_C = 3 A / I_B = 375 mA, DC current gain of 10–50 at I_C = 3 A, and DPAK thermal resistance of 8.3 °C/W (junction-to-case).

Technical Context

The MJD32CRLG is a silicon planar epitaxial PNP bipolar junction transistor optimized for linear amplification and hard-switching in medium-power circuits. Its design supports operation up to +150 °C junction temperature and includes ESD protection rated at HBM Class 3B (≥8 kV) and MM Class M3 (≥400 V).

It features complementary pairing with the NPN MJD31CRLG, enabling push-pull and H-bridge topologies. The device uses straight-lead DPAK packaging with Pb-free (RoHS-compliant) construction and meets UL 94 V-0 flammability rating at 3.18 mm thickness.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	100 V - Maximum collector-emitter voltage before breakdown under open-base conditions; enables use in 48 V and 72 V industrial bus systems.
I_C (continuous)	3.0 A - Continuous collector current rating; supports load switching up to ~30 W at moderate duty cycles with heatsinking.
P_D @ T_C = 25 °C	15 W - Total power dissipation at case temperature 25 °C; requires thermal pad and ≥165 mm² copper area for full rating.
V_CE(sat)	1.2 V max at I_C = 3 A, I_B = 375 mA - Low saturation voltage reduces conduction loss and heat generation in switching applications.
h_FE	10–50 at I_C = 3 A, V_CE = 4 V - Moderate DC current gain suitable for base-driven switching without excessive drive current overhead.
f_T	3 MHz - Current-gain-bandwidth product; confirms suitability for audio-frequency amplification and <100 kHz switching.
R_θJC	8.3 °C/W - Junction-to-case thermal resistance; defines minimum heatsink requirement when mounted on recommended PCB pad.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP power transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP16PF10	100 V, 16 A MOSFET in TO-220; gate-driven, no base current required; R_DS(on) = 0.12 Ω typical.	Replaces BJT with FET for higher efficiency and zero gate drive power; unsuitable for linear amplification due to transconductance nonlinearity.	Select STP16PF10 when switching efficiency and zero static base current outweigh need for analog linearity or simple bipolar drive.
MJD32CT4G	Identical electrical specs and DPAK package; differs only in tape-and-reel quantity (2,500 vs. 1,800 units) and reel width.	No functional or layout difference; both support same PCB footprint and thermal design; interchangeability confirmed by onsemi ordering matrix.	Choose MJD32CT4G for higher-volume SMT lines requiring larger reels; MJD32CRLG preferred for mid-volume builds or prototyping flexibility.

Compared with MJD32CRLG, STP16PF10 offers superior switching efficiency but lacks linear gain control, while MJD32CT4G provides identical performance with different packaging logistics-making it a direct logistical alternative rather than a technical substitute.

FAQ

What is the maximum junction temperature rating for the MJD32CRLG?

The MJD32CRLG has an operating junction temperature range of −65 °C to +150 °C, as specified in the Absolute Maximum Ratings table. This allows deployment in harsh environments such as engine compartments, industrial enclosures, and outdoor power systems. Derating curves in Figure 1 confirm full 15 W power dissipation is only valid below 25 °C case temperature; above that, thermal resistance dictates linear reduction per 0.12 W/°C.

Is the MJD32CRLG pin-compatible with the older TIP32 series?

Yes, the MJD32CRLG is electrically similar to the TIP32 series and shares the same DPAK pinout (base-collector-emitter-collector), but it is not mechanically pin-compatible with TO-220-packaged TIP32 devices. The MJD32CRLG requires surface-mount layout with thermal pad; direct replacement in through-hole designs necessitates board redesign and footprint adaptation.

Does the MJD32CRLG require a heatsink in standard operation?

The MJD32CRLG requires thermal management proportional to power dissipation: at 15 W, its R_θJC = 8.3 °C/W implies a 124.5 °C rise above case temperature-exceeding safe limits without heatsinking. For reliable operation above 1 W, a copper thermal pad (≥165 mm², 1 oz Cu) is mandatory; additional external heatsink is needed for sustained >5 W dissipation.

What does the "RLG" suffix mean in MJD32CRLG?

The "RLG" suffix in MJD32CRLG indicates a DPAK-packaged, Pb-free (RoHS-compliant) device supplied in 1,800-unit tape-and-reel format. "R" denotes tape-and-reel, "L" specifies 16 mm carrier tape width, and "G" confirms Pb-free construction per onsemi's standardized naming convention documented in the Ordering Information section.

Can the MJD32CRLG be used in linear amplifier applications?

Yes, the MJD32CRLG is explicitly designed for general-purpose amplifier applications, with verified h_FE stability across −55 °C to +150 °C (Figures 15–16) and low distortion characteristics in Class AB output stages. Its f_T = 3 MHz and consistent V_BE(on) behavior support audio-frequency amplification up to 20 kHz with proper biasing and thermal design.
