Typical Applications
BSZ15DC02KDHXTMA1 is suitable for 6 applications: Smartphone & Wearable Battery Protection, USB OTG & Charger-Path Multiplexer, Automotive Body & Lighting Loads, Small DC Motor Half-Bridge, LED Backlight & Indicator Drivers, Hot-Swap & eFuse Load Switch.
Smartphone & Wearable Battery Protection
The BSZ15DC02KDHXTMA1 fits smartphone and wearable battery protection because its 20 V VDS, 5.1 A N-channel, and 3.2 A P-channel ratings cover the worst-case single-cell Li-ion transients (up to 4.4 V) while sourcing more than 3 A of discharge current for power-hungry SoCs. The TSDSON-8 (3.3 x 3.3 mm) footprint is roughly 60 percent smaller than two discrete SO-8 parts, which frees board area for larger batteries. With 2.5 V Super Logic level gate drive, a 1.8 V or 3.3 V fuel-gauge GPIO can drive the part directly without a charge pump. Per the Infineon BSZ15DC02KD datasheet, the common-drain configuration also enables a back-to-back protection switch that blocks reverse-current leakage during shipping-mode storage.
Recommended
USB OTG & Charger-Path Multiplexer
The BSZ15DC02KDHXTMA1 works well in USB OTG and charger-path multiplexers because its 2.5 V gate rating matches 1.8 V/3.3 V USB-PHY GPIO outputs, and the 5.1 A N-channel handles the full USB-C 3.0/3.1 5 V @ 900 mA and 1.5 A paths plus margin. The P-channel half (3.2 A, 55 mOhm RDS(on)) can act as the reverse-blocking element when the device is in sink mode, eliminating a Schottky diode. The TSDSON-8 (PG-TSDSON-8-FL) package is footprint-compatible with most USB switch footprints, allowing drop-in redesign. Per Infineon's OptiMOS™2 documentation, the low RDS(on) minimizes voltage drop and keeps USB voltage compliance at 5 V +/- 5 percent even at 1.5 A.
Recommended
Automotive Body & Lighting Loads
The BSZ15DC02KDHXTMA1 is AEC-Q101 qualified per Infineon's family documentation, making it directly usable in automotive body-control modules, LED drivers, and small DC motor half-bridges. The 20 V VDS easily survives 12 V load-dump transients up to about 35 V when paired with a TVS clamp, while the 5.1 A N-channel current handles incandescent bulbs up to ~50 W and high-brightness LED strings at full PWM duty. The 175 °C maximum junction temperature gives ample thermal margin in underhood or dashboard environments. Compared with older DPAK discrete pairs, the TSDSON-8 outline saves roughly 80 percent of PCB area, allowing smaller ECUs.
Recommended
Small DC Motor Half-Bridge
The BSZ15DC02KDHXTMA1's complementary pair inside one TSDSON-8 package is a natural fit for a small brushed DC motor half-bridge, since the N-channel (5.1 A) drives the low side and the P-channel (3.2 A) drives the high side from the same 5 V or 12 V rail. The 2.5 V Super Logic level gate drive lets a 3.3 V MCU PWM the gates directly at up to 100 kHz without a gate driver. The Infineon BSZ15DC02KD datasheet avalanche rating also improves robustness against the inductive kick of small motors. For full H-bridge control, two BSZ15DC02KDHXTMA1 devices occupy just two TSDSON-8 footprints versus four discretes.
Recommended
LED Backlight & Indicator Drivers
The BSZ15DC02KDHXTMA1 fits LED backlight and indicator driver stages, where the N-channel half can PWM at up to about 1 MHz to dim LED strings while the P-channel half provides high-side disconnect for shutdown. Its 20 V VDS comfortably handles 12 V LED rails with margin, and the 5.1 A continuous rating covers parallel LED strings up to several watts per channel. The 55 mOhm RDS(on) on the P-channel keeps conduction losses low; for example, at 1 A the P-channel drops only 55 mV (P = 55 mW). The TSDSON-8 outline enables compact backlight PCBs under smartphone LCDs and dashboard displays.
Recommended
Hot-Swap & eFuse Load Switch
The BSZ15DC02KDHXTMA1 can serve as the switching element in a compact hot-swap or eFuse load switch for 5 V to 12 V rails. The N-channel device handles the inrush surge (5.1 A continuous, higher pulsed) while the P-channel half provides reverse-current blocking. The 2.5 V gate drive simplifies the controller design, and the 175 °C junction rating supports high ambient enclosures. Per Infineon OptiMOS™2 family data, the device's avalanche rating also helps absorb transients during connector hot-plug events on server and telecom boards.

Key Differentiators
- Complementary N+P pair in a single 3.3 x 3.3 mm package (vs Single N-channel alternatives such as BSS205NH6327XTSA1)
- 2.5 V Super Logic level gate drive (vs Standard 4.5 V logic-level MOSFETs in TSDSON-8)
- 20 V VDS with 5.1 A N-channel rating (vs BSD235CH6327XTSA1 (Infineon TSDSON-8 complementary pair))
Design Notes
The BSZ15DC02KDHXTMA1 is rated at 2.5 W total package dissipation on a JESD51 4-layer test board. Estimated: on a 1 oz copper, 1 square inch copper-pour pad under the exposed die, theta_JA rises to roughly 60 C/W. At 1.5 A load through the N-channel half at VIN=5 V and VOUT=0 V (full-load condition), power dissipation would be 7.5 W, which exceeds the 2.5 W rating. Either derate the current to ~0.5 A continuous, increase copper area, or use a topside heatsink. Always confirm thermal margin with a thermocouple measurement on the final PCB.
Per Infineon's PG-TSDSON-8-FL layout guide, route the N-channel and P-channel gate traces as short as possible and surround them with a ground pour to minimize switching noise injection. Place at least one 10 nF ceramic bypass capacitor near the VCC rail feeding the device. Keep the high-current source/drain traces wide (>= 0.5 mm per 1 A) to limit voltage drop, and stitch the ground pour with multiple vias around the exposed pad for thermal dissipation.
Do not parallel the N-channel and P-channel halves by accident: the BSZ15DC02KDHXTMA1 is wired in a common-drain configuration, not a half-bridge. Mistaking the pinout will short the rails. Always re-verify against the Infineon BSZ15DC02KD datasheet pin diagram before PCB fabrication. Also note the 2.5 V gate rating: driving the gates below 2.5 V will leave the part in linear region and cause severe self-heating.
The PG-TSDSON-8-FL exposed pad (EP) is the primary thermal path and must be soldered to a copper pad of at least 1 square inch with thermal vias to internal ground planes. Missing solder on the EP can raise junction temperature by 30-40 C at 2 W dissipation, dramatically reducing reliability. Per Infineon's application note on small-outline MOSFETs, use 4-8 thermal vias in a 0.3 mm drill pattern to maximize heat transfer.
