Diodes Incorporated DXTP03100BFG-7

Overview

DXTP03100BFG-7 from Diodes Incorporated is a 100V PNP bipolar junction transistor in PowerDI3333-8 package, designed for high-current switching with V_CE(sat) < −90 mV at −1 A, R_SAT = 56 mΩ, and continuous I_C = −5 A. It operates up to +175°C and serves as a high-side switch in motor drive circuits.

For engineers reviewing the DXTP03100BFG-7 datasheet, DXTP03100BFG-7 pinout, DXTP03100BFG-7 application, or DXTP03100BFG-7 equivalent, key selection criteria include guaranteed h_FE ≥ 25 at −4 A, wettable flank leads for automated optical inspection, and thermal resistance R_θJL = 6 °C/W for high-power density PCB layouts.

Technical Context

This PNP transistor features a rugged silicon die rated for −140 V V_CBO and −100 V V_CEO, with pulsed I_CM = −10 A and specified h_FE down to −10 A (min 5). Its low saturation voltage and high gain hold-up enable efficient DC switching in thermally constrained environments.

The PowerDI3333-8 package integrates a copper leadframe with exposed collector tab, delivering R_θJA = 44 °C/W on 50 mm × 50 mm 2 oz copper and supporting JEDEC Class 3A HBM ESD rating (4 kV). Wettable flanks ensure solder-joint quality verification via AOI.

FAQ

What is the maximum safe operating temperature for DXTP03100BFG-7?

The device is rated for continuous operation from −55 °C to +175 °C junction temperature. At ambient temperatures above +85 °C, derating is required per the thermal curves in DS41053 Rev. 1–2, with R_θJA = 44 °C/W on 50 mm × 50 mm 2 oz copper. The +175 °C rating reflects qualification testing, not recommended steady-state limit without thermal modeling.

Does DXTP03100BFG-7 require a base resistor, and how is its value calculated?

Yes - base current must be sized to ensure saturation. For I_C = −4 A, h_FE ≥ 15 (min), so I_B ≥ −267 mA. With V_BE(sat) ≈ −967 mV and 3.3 V logic drive, R_B ≤ (3.3 V − 0.967 V)/0.267 A ≈ 8.7 Ω. A 8.2 Ω, 1 W resistor is recommended for reliability and thermal margin.

Can DXTP03100BFG-7 replace a mechanical relay in 24 V DC control circuits?

Yes - with verified performance in 24 V high-side switching at up to −5 A continuous. Its t_fall = 127 ns and t_storage = 1340 ns enable fast turn-off, while V_CE(sat) < −150 mV at −2 A limits power loss to < 300 mW. Unlike relays, it offers silent operation, no contact wear, and 10× faster cycling, but requires flyback diode protection for inductive loads.

Is the PowerDI3333-8 package compatible with standard reflow profiles?

Yes - the device is rated Moisture Sensitivity Level 1 per J-STD-020 and supports standard lead-free reflow (peak 260 °C, 20–40 sec above 217 °C). The matte tin finish meets MIL-STD-202 Method 208 solderability requirements, and the package outline matches IPC-7351B SOIC-8 land patterns with adjusted thermal pad dimensions per Diodes' suggested pad layout (DS41053 p.6).
