Product details
Overview
DSS5220T-13 from Diodes Incorporated is a 20V PNP low-saturation transistor in SOT23 package, designed for high-efficiency switching in space-constrained DC-DC converters and load switches. It delivers -2A continuous collector current, -150mV VCE(sat) at -1A, and 113mΩ equivalent on-resistance, enabling low-loss power path control in automotive body electronics and industrial I/O modules.
For engineers reviewing the DSS5220T-13 datasheet, DSS5220T-13 pinout, DSS5220T-13 application, or DSS5220T-13 equivalent, key selection criteria include verified PNP saturation performance at -2A, thermal resistance (RθJA = 209°C/W on minimal pad), AEC-Q101 readiness via companion part DSS5220TQ, and SOT23 lead-free compliance with J-STD-020 Level 1 moisture sensitivity.
Technical Context
This PNP bipolar junction transistor operates with a guaranteed -20V VCEO and -7V VEBO, supporting robust voltage margin in 12V automotive and 5V industrial rail-switching applications. Its hFE ranges from 150 to 225 across -100mA to -2A collector currents, ensuring stable gain under varying load conditions.
With 100MHz fT and sub-200ns turn-on/turn-off times, it supports medium-speed digital switching up to ~500kHz. The 4kV HBM ESD rating and -55°C to +150°C operating range confirm suitability for harsh-environment control nodes requiring reliable gate/base drive isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -20V - Ensures safe operation in 12V systems with transient spikes up to ±20V. |
| IC (continuous) | -2A - Supports sustained load switching for solenoids, LED arrays, and fan drivers. |
| VCE(sat) | <-150mV @ -1A - Minimizes conduction loss (≤150mW) in high-current linear-mode operation. |
| RCE(sat) | 113mΩ - Enables precise on-resistance modeling for thermal budgeting in PCB layout. |
| hFE | 150–225 - Provides predictable base drive requirements across full rated current range. |
| fT | 100MHz - Validates usable bandwidth for PWM frequencies up to 500kHz with margin. |
| ESD HBM | 4,000V - Confirms handling robustness during automated assembly without special precautions. |
Pinout & Package
Package: SOT23 - Surface-mount plastic package with 0.915mm nominal lead pitch, 2.40mm × 1.30mm footprint, and 0.40mm height; UL 94V-0 rated, J-STD-020 Level 1 moisture sensitivity, matte tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current source terminal | Connected to positive supply rail in high-side switch configuration; requires low-impedance return path. |
| 2 (Base) | Control input | Driven by logic-level signal (e.g., MCU GPIO); requires series resistor to limit IB to ≤200mA peak. |
| 3 (Collector) | Current sink terminal | Connected to load; voltage swing limited to ≤|VCEO| = 20V relative to emitter. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | <-150mV at -1A enables ≤0.15W conduction loss, reducing thermal stress in sealed enclosures. |
| High IC capability | -2A continuous rating allows direct driving of 24W resistive loads at 12V without external heat sinking. |
| Robust ESD protection | 4kV HBM rating eliminates need for external TVS diodes in board-level ESD protection schemes. |
| AEC-Q101 alignment | Companion automotive-grade variant DSS5220TQ exists with PPAP support and IATF 16949 manufacturing. |
| Green packaging | Halogen- and antimony-free compound (<900ppm Br+Cl, <1000ppm Sb) meets EU ELV and China RoHS requirements. |
Applications
| Automotive Door Module | Industrial PLC Output Stage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP low-saturation transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTN25050DFHTA | Higher VCEO (-50V), lower IC (-0.5A), SOT23-3 package, 150mV VCE(sat) @ -0.5A | Better voltage headroom but insufficient for 2A loads; suited for lower-power sensing circuits. | Select when >30V transient immunity is required and load current stays below 500mA. |
| MMBT4403 | Lower VCEO (-40V), same SOT23, but only -0.6A IC, 750mV VCE(sat) @ -0.5A | Higher conduction loss and lower current capacity; lacks automotive qualification path. | Choose only for cost-sensitive non-automotive prototypes where thermal margin is abundant. |
Compared with ZXTN25050DFHTA and MMBT4403, DSS5220T-13 uniquely balances -2A current, -150mV saturation, and automotive-aligned qualification-making it optimal for production-grade 12V/24V load switching where both power density and reliability are critical.

FAQ
Is DSS5220T-13 qualified to AEC-Q101?
No-DSS5220T-13 is the commercial-grade version. The automotive-qualified variant is DSS5220TQ, which undergoes full AEC-Q101 stress testing, PPAP documentation, and is manufactured in IATF 16949-certified facilities. DSS5220T-13 shares identical electrical specs and package but lacks formal automotive certification.
What is the maximum allowable power dissipation at 85°C ambient?
At TA = 85°C, derated power dissipation is 0.72W using the 1.2W rating (Note 6) and RθJA = 104°C/W on 25mm × 25mm copper. This assumes still-air conditions and proper solder joint thermal conduction; actual PCB layout must provide ≥25mm² of 1oz copper connected to collector pad.
Can DSS5220T-13 be used in linear regulation mode?
Yes-it supports linear operation with verified VCE(sat) down to -250mV at -2A and stable hFE across current range. However, thermal design must account for up to 0.5W dissipation at full current; use with caution in unventilated enclosures above 60°C ambient.
Does the SOT23 package support reflow soldering per JEDEC J-STD-020?
Yes-DSS5220T-13 is rated for Moisture Sensitivity Level 1, permitting unlimited floor life and standard Pb-free reflow profiles (peak 260°C, 30s max). The matte tin plating meets MIL-STD-202 Method 208 for solderability, and UL 94V-0 molding compound withstands repeated thermal cycling.
