Product details
Overview
NJVMJB41CT4G from onsemi is an NPN silicon power transistor in D2PAK (TO-263) surface-mount package, rated for 100 VCEO, 6.0 A continuous collector current, and 65 W total power dissipation at TC = 25 °C. It delivers VCE(sat) ≤ 1.5 V at IC = 6.0 A / IB = 600 mA and supports automotive-grade operation per AEC-Q101 with Pb-free packaging.
For engineers reviewing the NJVMJB41CT4G datasheet, pinout, applications, or equivalent options, this device serves as a high-current switching element in DC motor drives, linear regulators, and industrial power control circuits where thermal robustness and rugged unclamped inductive load handling (62.5 mJ) are required.
Technical Context
This NPN bipolar junction transistor operates in linear and saturated switching modes with hFE ranging from 15 to 75 (IC = 3.0 A, VCE = 4.0 V), and exhibits fT = 3.0 MHz under standard test conditions (IC = 500 mA, VCE = 10 V). Its safe operating area (SOA) is defined up to 100 V and 6 A for single-pulse operation at TJ(pk) = 150 °C.
The device features low thermal resistance RJC = 1.92 °C/W and RJA = 50 °C/W when surface-mounted on FR-4, enabling efficient heat transfer from junction to case and ambient. It supports unclamped inductive switching with E = 62.5 mJ (IC = 2.5 A, L = 20 mH, VCC = 10 V, P.R.F. = 10 Hz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 100 V - Maximum collector-emitter voltage before breakdown under open-base condition; defines upper voltage limit in switching applications. |
| IC (cont.) | 6.0 A - Continuous collector current rating at TC = 25 °C; determines steady-state load-handling capability. |
| PD @ TC = 25 °C | 65 W - Maximum power dissipation at case temperature of 25 °C; sets thermal design baseline for heatsink sizing. |
| VCE(sat) | ≤1.5 V @ IC/IB = 10 - Low saturation voltage minimizes conduction loss in switching mode, critical for efficiency in motor drivers. |
| RJC | 1.92 °C/W - Junction-to-case thermal resistance; enables direct thermal interface to heatsink without PCB trace bottleneck. |
| AEC-Q101 | Qualified - Meets stress-test requirements for automotive electronics, including temperature cycling, HTRB, and ESD. |
| Unclamped Energy | 62.5 mJ - Maximum energy absorbed during inductive turn-off without failure; supports robust relay/motor coil driving. |
Pinout & Package
D2PAK (TO-263) plastic surface-mount package with 3-pin configuration (pin 4 is internal collector tab connection); thermally enhanced for high-power dissipation and compatible with automated reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Base | Control input terminal; requires ≥600 mA base drive for full saturation at 6 A collector current. |
| Pin 2 | Collector | Main high-current output path; electrically connected to exposed metal tab (Pin 4) for thermal and electrical conduction. |
| Pin 3 | Emiter | Current return path; referenced to system ground in common-emitter configurations. |
| Pin 4 (Tab) | Collector (thermal & electrical) | Exposed copper pad on underside; must be soldered to large copper pour for thermal management and low-inductance collector routing. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood applications including engine control modules and body electronics. |
| 65 W power rating @ TC = 25 °C | Enables high-current switching without external heatsink in moderate-duty cycles or with minimal thermal interface. |
| Low VCE(sat) ≤ 1.5 V | Reduces conduction losses by >30% vs. legacy TIP41C equivalents, improving thermal margin in compact designs. |
| Rugged unclamped inductive switching | 62.5 mJ energy rating allows direct driving of solenoids, relays, and DC motors without snubber networks. |
| Pb-free D2PAK package | Complies with RoHS and JEDEC J-STD-020 reflow profiles; eliminates lead contamination risk in production. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MJB41CT4G | No NJV prefix; not AEC-Q101 qualified; identical electrical specs and D2PAK package. | Suitable for commercial/industrial use only; lacks automotive change control and PPAP documentation. | Select when AEC-Q101 compliance is unnecessary and cost sensitivity outweighs qualification requirements. |
| TIP41C | TO-220 through-hole package; same VCEO, IC, and hFE ratings but higher RJA (62.5 °C/W) and no AEC-Q101. | Requires manual assembly or wave soldering; less suitable for high-density SMT layouts or automotive vibration environments. | Choose only for legacy board redesigns where footprint compatibility and through-hole mounting are mandatory. |
Compared with MJB41CT4G and TIP41C, NJVMJB41CT4G provides verified AEC-Q101 qualification, Pb-free D2PAK packaging, and identical electrical performance-making it the sole option for new automotive designs requiring PPAP support and surface-mount scalability.

FAQ
What is the maximum continuous collector current rating for NJVMJB41CT4G?
The NJVMJB41CT4G is rated for 6.0 A continuous collector current at case temperature TC = 25 °C. Derating applies above 25 °C at 0.52 W/°C. This rating assumes proper thermal management via the exposed collector tab (Pin 4) soldered to a sufficient copper area on the PCB.
Is NJVMJB41CT4G pin-compatible with the legacy TIP41C transistor?
No-NJVMJB41CT4G uses a D2PAK (TO-263) surface-mount package with 3 active pins plus thermal tab, whereas TIP41C uses a TO-220 through-hole package with 3 pins in different physical layout and thermal structure. Electrical characteristics are comparable, but PCB footprint and assembly process are not interchangeable.
Does NJVMJB41CT4G require a heatsink in typical applications?
Yes-while NJVMJB41CT4G achieves RJC = 1.92 °C/W, its 65 W power rating assumes direct thermal coupling to a heatsink or large copper plane. At full 6 A load with 2 V drop, ~12 W dissipation requires ≥4 °C/W system thermal resistance to hold TJ ≤ 150 °C; thus a heatsink or substantial PCB copper is essential.
What does the "NJV" prefix signify in NJVMJB41CT4G?
"NJV" denotes onsemi's automotive-grade variant: unique site and process control, AEC-Q101 qualification, PPAP capability, and enhanced traceability. It is functionally identical to MJB41CT4G but meets additional automotive quality and documentation requirements for safety-critical systems.
Can NJVMJB41CT4G be used in linear regulator applications?
Yes-NJVMJB41CT4G is commonly deployed as a series pass element in high-current linear regulators. Its 100 V VCEO, 6.0 A IC, and low VCE(sat) support stable regulation under heavy loads; however, thermal design must accommodate power dissipation (P = IOUT × VIN−OUT) using the RJC and RJA values specified in the datasheet.
