onsemi NJVMJK45H11TWG

Overview

NJVMJK45H11TWG from onsemi is a general-purpose PNP power transistor rated for −80 V V_CEO, −8 A continuous collector current, and 20 W power dissipation at T_A = 25°C in LFPAK4 (5 × 6 mm) package. It operates with V_CE(sat) ≤ −1.0 V at I_C = −8 A / I_B = −0.4 A and supports automotive applications including airbag deployment and powertrain control units.

For engineers reviewing the NJVMJK45H11TWG datasheet, pinout, applications, or equivalent options, key selection factors include its AEC−Q101 qualification, −65°C to +150°C junction temperature range, R_θJA = 70°C/W on FR4, complementary NPN pairing with MJK44H11, and LFPAK4 thermal performance.

Technical Context

This PNP bipolar junction transistor delivers high-current switching capability with low saturation voltage and robust thermal design via the LFPAK4 package's copper-exposed die pad. Its h_FE ≥ 60 at I_C = −2 A and ≥ 40 at I_C = −4 A enables stable DC gain across load ranges, while f_T = 90 MHz supports moderate-frequency switching in power converters.

The device features V_CEO(sus) = −80 V under I_C = −30 mA / I_B = 0, C_cb = 130 pF at V_CB = 10 V, and is qualified per AEC−Q101 with PPAP capability - confirming suitability for automotive safety-critical subsystems requiring traceable, controlled manufacturing.

FAQ

What is the maximum continuous collector current rating for NJVMJK45H11TWG?

The NJVMJK45H11TWG has a maximum continuous collector current (I_C) rating of −8 A at T_A = 25°C. This rating assumes proper PCB thermal design with a 1 in², 2 oz copper pad. Derating applies above 25°C ambient, per the power derating curve in Figure 8 of the datasheet. The NJVMJK45H11TWG maintains this current capability within its −65°C to +150°C junction temperature range.

Is NJVMJK45H11TWG qualified for automotive applications?

Yes, the NJVMJK45H11TWG is AEC−Q101 qualified and PPAP capable, with the "NJV" prefix indicating dedicated automotive manufacturing controls and traceability. It is explicitly designed for automotive end applications including airbag deployment, powertrain control units, and instrument clusters - meeting stringent reliability and process validation requirements for safety-critical systems.

What package type does NJVMJK45H11TWG use, and why is it significant?

The NJVMJK45H11TWG uses the LFPAK4 (Case 760AB) 5 × 6 mm surface-mount package. Its significance lies in the exposed copper drain pad that achieves R_θJC = 6°C/W, enabling 20 W power dissipation without an external heatsink when mounted on appropriate PCB copper. This makes the NJVMJK45H11TWG ideal for space-constrained automotive modules where thermal performance and reliability are critical.

What is the typical DC current gain (h_FE) of NJVMJK45H11TWG at different operating points?

The NJVMJK45H11TWG specifies h_FE ≥ 60 at V_CE = −1 V and I_C = −2 A, and ≥ 40 at V_CE = −1 V and I_C = −4 A. These values reflect stable current amplification across common automotive load conditions. The NJVMJK45H11TWG maintains usable gain up to its −8 A rating, supporting predictable base drive design in both linear and saturated switching applications.

Does NJVMJK45H11TWG have a complementary NPN transistor?

Yes, the NJVMJK45H11TWG has a complementary NPN counterpart: the MJK44H11. Both devices share matching voltage, current, and thermal specifications and are optimized for use in push-pull, H-bridge, and differential amplifier configurations. This pairing simplifies design of bidirectional power stages in automotive motor drivers and converter topologies using the NJVMJK45H11TWG.
