Product details
Overview
DSS2515M-7B from Diodes Incorporated is a 15V NPN low-saturation transistor in X1-DFN1006-3 package, designed for high-efficiency switching in space-constrained DC-DC converters and load switches. It delivers 500mA continuous collector current, 1A peak pulse current, and ultra-low VCE(sat) of 250mV at 500mA/50mA drive, enabling minimal conduction loss in portable power management.
For engineers reviewing the DSS2515M-7B datasheet, DSS2515M-7B pinout, DSS2515M-7B application, or DSS2515M-7B equivalent, key selection criteria include its 15V VCEO, 0.60mm² footprint (13× smaller than SOT-23), 120°C/W junction-to-lead thermal resistance, and AEC-Q101-qualified complementary PNP DSS3515M pairing capability.
Technical Context
This NPN transistor operates as a low-voltage, high-current switch with guaranteed BVCEO ≥15V and VEBO = 6V, supporting robust operation in 12V automotive and industrial supply rails. Its fT = 250MHz enables stable switching up to several tens of MHz in PWM-controlled regulators.
The device uses an exposed-collector DFN package with NiPdAu terminals, achieving RθJL = 120°C/W for direct heat transfer to PCB copper. Thermal performance is validated per JESD51-14 for single-pulse and duty-cycle-dependent transient dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 15V - Ensures safe operation in 12V nominal systems with margin against transients. |
| IC (continuous) | 500mA - Supports medium-power loads such as LED drivers and sensor bias circuits. |
| VCE(sat) @ 500mA | 250mV - Limits conduction loss to ≤125mW, critical for thermally constrained PCBs. |
| fT | 250MHz - Enables stable high-frequency switching in synchronous buck controllers. |
| RθJL | 120°C/W - Allows direct thermal coupling to 25mm² copper pour for sustained 400mW dissipation. |
| Package | X1-DFN1006-3 - 1.0×0.6mm footprint with 0.5mm height, optimized for ultra-thin mobile modules. |
| ESD HBM | 4kV - Meets IEC 61000-4-2 Level 3 for board-level ESD immunity without external protection. |
Pinout & Package
Package: X1-DFN1006-3 - 3-terminal leadless plastic package with exposed collector pad (pin 1), emitter (pin 2), and base (pin 3) on bottom view. Dimensions: 1.00 × 0.60 × 0.50 mm, 0.0009g mass, UL 94V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Exposed Pad) | Collector | Primary heat path to PCB; must be soldered to ≥25mm² 2oz copper for rated 1000mW dissipation. |

| Pin 3 | Base | Current-controlled input; requires 50mA drive for full 500mA switching with 250mV VCE(sat). |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile packaging | 0.5mm height minimizes system Z-height in wearables and slim IoT sensors. |
| High current density | 500mA continuous in 0.60mm² area enables replacement of larger SOT-23 transistors. |
| Thermally enhanced layout | Exposed collector pad reduces RθJL to 120°C/W, enabling >2× power handling vs. standard DFN. |
| Automotive-grade compatibility | JEDEC-qualified and AEC-Q101-capable via Q-suffix variants; supports PPAP in IATF 16949 facilities. |

Applications
| USB Power Delivery Switching | Automotive Cabin Lighting Control |
|---|---|
|
Use Scenario: High-side load switch for USB-C port power enable/disable with fast turn-on/turn-off. IC Role / Device Role / Timing Role: NPN transistor configured as grounded-emitter switch controlling 5V/3A rail via base drive from MCU GPIO. Use Value: 250mV VCE(sat) limits voltage drop to <0.3% at full load, preserving PD compliance margins. |
Use Scenario: Dimmable LED driver stage in automotive dome lights and map lamps. IC Role / Device Role / Timing Role: Low-side PWM switch modulating current through 12V LED strings at 1–20kHz. Use Value: 250MHz fT ensures clean square-wave edges with <50ns rise/fall, eliminating audible coil whine. |
| Industrial Sensor Bias Supply | Portable Medical Device Load Switch |
|
Use Scenario: Precision current source for analog sensor excitation (e.g., RTD, bridge sensors) in PLC modules. IC Role / Device Role / Timing Role: Constant-current sink using feedback-controlled base drive to regulate 10–100mA sensor bias. Use Value: hFE = 150 @ 100mA ensures stable gain across temperature (−55°C to +150°C), minimizing calibration drift. |
Use Scenario: Battery-isolation switch in handheld diagnostic tools with dual Li-ion cells. IC Role / Device Role / Timing Role: Reverse-polarity and overcurrent-protected main power path controlled by safety MCU. Use Value: 4kV HBM rating eliminates need for external TVS in compact medical enclosures meeting IEC 60601-1 creepage requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN low-saturation transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DSS3515M | Complementary PNP; same VCEO = 15V, IC = 500mA, but VEC(sat) = 250mV @ −500mA. | Required for push-pull or H-bridge topologies where both polarities needed. | Select when designing bidirectional current control or level-shifting interfaces. |
| DMN2053UVT-7 | MOSFET (20V VDS, 0.5Ω RDS(on)); gate-driven, no base current, but higher gate charge (1.4nC). | Better for high-frequency (>1MHz) switching; unsuitable for linear-mode biasing due to threshold variation. | Choose for zero-base-current digital switching where gate drive is available and VGS ≥2.5V. |
Compared with DSS2515M-7B, DSS3515M enables complementary bipolar designs with matched thermal and saturation behavior, while DMN2053UVT-7 trades base-drive simplicity for lower static loss above 100kHz-but requires gate driver circuitry and lacks the DSS2515M-7B's precise hFE-based linear control capability.

FAQ
What is the maximum allowable continuous power dissipation for DSS2515M-7B under standard PCB conditions?
The DSS2515M-7B has a rated PD of 400mW when mounted on minimum recommended 2oz copper pad layout on a single-sided FR4 board. With the exposed collector pad soldered to 25mm × 25mm 2oz copper, it supports up to 1000mW continuous dissipation, confirmed per JEDEC JESD51-2 and JESD51-14 thermal testing standards.
Can DSS2515M-7B be used in linear-regulator pass-transistor applications?
Yes-its specified VCE(sat) down to 25mV at low currents and hFE stability from −55°C to +150°C make it suitable for precision current-source and low-dropout linear regulator topologies. However, thermal derating must follow the transient thermal resistance curve (Figure 1) for non-pulsed DC operation.
Is the DSS2515M-7B pinout compatible with standard DFN1006 footprints?
Yes-the X1-DFN1006-3 package matches JEDEC MO-301 and industry-standard DFN1006 land patterns. Pin 1 (exposed collector) aligns with the bottom-left corner per Diodes' mechanical drawing DS31816 Rev. 5-2, and the 0.35mm pitch between pins 2 and 3 is fully compatible with IPC-7351B Class L footprints.
Does DSS2515M-7B meet AEC-Q101 stress-test requirements?
The DSS2515M-7B itself is not AEC-Q101 qualified, but Diodes offers the automotive-grade DSS2515MQ-7B variant (Q-suffix) that undergoes full AEC-Q101 testing-including HTGB, ELFR, and temperature cycling-in IATF 16949-certified facilities. The base design shares identical die and package construction.
