Product details

Overview

FJPF5021RTU from onsemi is an NPN silicon power transistor in TO-220 Fullpack package, rated for 500 V VCEO, 5 A IC (DC), and 40 W PC at TC = 25°C; designed for high-voltage switching in industrial motor drives and AC line-powered SMPS.

For engineers reviewing the FJPF5021RTU datasheet, pinout, applications, or equivalent options, key selection criteria include VCEO ≥ 500 V, SOA robustness under inductive switching, tF ≤ 0.3 µs, hFE ≥ 15 at 0.6 A, and TO-220F-3SG thermal performance with insulated tab.

Technical Context

This device operates as a single NPN bipolar junction transistor with base-controlled current amplification. Its high VCEO (500 V) and wide Forward Bias Safe Operating Area support reliable operation in clamped inductive switching circuits up to 500 V sustain voltage (VCEX(sus)).

It delivers fast switching with tF = 0.1 µs (typ.) and tON = 0.5 µs (max), enabled by low Cob = 80 pF and fT = 15 MHz. The TO-220 Fullpack package provides mechanical insulation and direct heatsink mounting capability.

Key Specifications

VCEO500 V - supports primary-side switching in offline 400 VAC rectified supplies
IC (DC)5 A - enables continuous conduction mode operation in 200–300 W power stages
PC @ TC=25°C40 W - requires heatsink for >1.5 A sustained current at ambient >50°C
tF0.1 µs (typ.) - reduces switching losses in 20–100 kHz hard-switched converters
hFE1 @ IC=0.6 A15–50 - ensures stable base drive design across manufacturing lot variation
Cob80 pF - limits Miller-induced turn-on risk in high-dv/dt environments
VCE(sat)≤1 V @ IC=3 A, IB=0.6 A - keeps conduction loss <3 W at rated current

Pinout & Package

Package: TO-220 Fullpack (Case 221AT), 3-lead, insulated tab, vertical mounting with screw hole. Thermal resistance RθJC ≈ 0.625°C/W (typ.).

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN high-voltage switching applications.

Alternative PartTechnical DifferenceApplication DifferenceSelection Advice
ST13007VCEO = 400 V, IC = 8 A, TO-220 package, no insulated tabLimited to ≤350 V DC bus; requires insulating hardware for heatsink mountingSelect when higher IC is prioritized over voltage margin and board space permits added insulation
MJE13009VCEO = 400 V, fT = 4 MHz, tF = 0.5 µs, TO-220Slower switching increases losses above 20 kHz; lower VCEO restricts to 230 VAC-only designsChoose for cost-sensitive 50/60 Hz line-frequency applications where speed is not critical

Compared with ST13007 and MJE13009, the FJPF5021RTU provides superior voltage headroom (500 V vs. 400 V), faster switching (tF = 0.1 µs), and built-in electrical isolation - making it optimal for compact, high-reliability 400 VAC+ systems requiring minimal layout overhead.

FAQ

What is the maximum continuous collector current rating for FJPF5021RTU?

The FJPF5021RTU has a maximum continuous collector current (IC) rating of 5 A at case temperature TC = 25°C. Derating is required above 25°C per Figure 8 in the datasheet, with zero current allowed at TC = 150°C. At 100°C case temperature, the usable IC drops to approximately 2.5 A.

Does FJPF5021RTU have an electrically insulated package?

Yes, the FJPF5021RTU uses the TO-220 Fullpack (Case 221AT) package with an electrically insulated tab. This eliminates the need for mica washers or silicone pads when mounting to a heatsink, simplifying thermal design and improving reliability in high-isolation applications.

What is the typical fall time (tF) specification for FJPF5021RTU?

The typical fall time (tF) for FJPF5021RTU is 0.1 µs, with a maximum of 0.3 µs under standard test conditions (VCC = 200 V, IC = 4 A, RL = 50 Ω). This fast switching characteristic reduces dynamic losses in high-frequency power converters.

Can FJPF5021RTU be used as a direct replacement for MJE13009?

No, FJPF5021RTU is not a direct replacement for MJE13009 due to differences in VCEO (500 V vs. 400 V), switching speed (tF = 0.1 µs vs. 0.5 µs), and package insulation. While both are NPN TO-220 transistors, the FJPF5021RTU offers higher voltage capability and faster response but requires verification of base drive compatibility and PCB thermal layout.

What is the minimum DC current gain (hFE) of FJPF5021RTU at 0.6 A collector current?

The minimum DC current gain (hFE1) of FJPF5021RTU at VCE = 5 V and IC = 0.6 A is 15, per the hFE classification table. The actual hFE varies by grade (R/O/Y), with the 'R' grade specifying 15–30, ensuring predictable base drive requirements across production lots.
