Product details
Overview
DSS5220TQ from Diodes Incorporated is a 20V PNP low-saturation bipolar junction transistor in SOT23 package, rated for −2A continuous collector current, −20V VCEO, and VCE(sat) ≤ −150mV at −1A. It delivers RCE(sat) = 113mΩ and is AEC-Q101 qualified for automotive power switching applications including load control and reverse-polarity protection.
For engineers reviewing the DSS5220TQ datasheet, DSS5220TQ pinout, DSS5220TQ application, or DSS5220TQ equivalent, key selection criteria include verified −2A DC current handling, low −150mV saturation voltage under −1A load, AEC-Q101 qualification status, SOT23 thermal resistance (RθJA = 209°C/W on minimal PCB), and confirmed PNP polarity with emitter-base breakdown of −7V.
Technical Context
This PNP transistor operates as a high-current, low-VCE(sat) switch in DC power paths where fast turn-on/turn-off and minimal conduction loss are critical. Its hFE ≥ 200 at −1A enables efficient base drive with modest IB, while fT = 100MHz supports moderate-speed switching up to ~100kHz in PWM-controlled loads.
Designed for automotive-grade reliability, it features IATF16949-manufactured construction, 4kV HBM ESD rating, and guaranteed operation from −55°C to +150°C. The SOT23 package provides standardized solderability with matte tin-plated leads and J-STD-020 Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −20V - Maximum allowable collector-emitter voltage before breakdown in common-emitter configuration. |
| IC (continuous) | −2A - Sustained DC load current capability without thermal runaway under defined PCB layout conditions. |
| VCE(sat) | ≤ −150mV @ −1A/−50mA - Low conduction loss enabling <150mW dissipation per watt of switched load power. |
| RCE(sat) | 113mΩ - Equivalent on-resistance directly determining I²R heating during saturation. |
| hFE | ≥200 @ −1A - Sufficient DC current gain to support simple resistor-based base drive circuits. |
| fT | 100MHz - Transition frequency indicating usable bandwidth for switching signals up to ~100kHz with margin. |
| TJ range | −55°C to +150°C - Full operational junction temperature range validated for under-hood automotive environments. |
Pinout & Package
Package: SOT23 - Surface-mount plastic package with 3 terminals, 0.008g mass, UL 94V-0 flammability rating, and J-STD-020 Level 1 moisture sensitivity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | E | Current source terminal; connects to higher potential rail in PNP high-side switch configurations. |
| 2 (Base) | B | Control input; requires negative bias relative to emitter to enable conduction (−100mA max peak drive). |
| 3 (Collector) | C | Current sink terminal; connects to load and ground return path in standard PNP switch topology. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use with PPAP documentation support and IATF16949 manufacturing traceability. |
| Low RCE(sat) | 113mΩ enables <230mW conduction loss at −2A, reducing thermal stress in space-constrained modules. |
| High ESD robustness | 4kV HBM rating ensures resilience against assembly and in-system electrostatic events. |
| Green compound | Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb) meets global environmental compliance mandates. |
| Thermal performance | RθJL = 75°C/W allows direct heat transfer from junction to solder joint, improving transient thermal response. |
Applications

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 (−1.5A), RCE(sat) = 150mΩ @ −1A | Better voltage margin but reduced current capacity and higher conduction loss | Select when system voltage exceeds 20V or when footprint compatibility with SOT23-3 is required |
| MMDT5401-7-F | Lower VCEO (−160V), much lower IC (−200mA), VCE(sat) = −400mV @ −10mA | General-purpose signal switching only; unsuitable for >500mA loads | Use only for low-power biasing or logic-level translation, not power switching |
Compared with ZXTN25050DFHTA and MMDT5401-7-F, DSS5220TQ uniquely balances −2A current, −20V rating, and 113mΩ on-resistance in an AEC-Q101-qualified SOT23, making it optimal for automotive 12V/24V load switching where thermal efficiency and qualification are jointly critical.

FAQ
Is DSS5220TQ pin-compatible with standard SOT23 PNP transistors like MMBT3906?
No. While both use SOT23-3 packaging, DSS5220TQ has emitter-base-collector pinout (1-E, 2-B, 3-C), whereas MMBT3906 uses emitter-collector-base (1-E, 2-C, 3-B). Incorrect PCB layout will result in non-functional or damaged circuit operation.
What is the maximum safe operating current at 100°C ambient temperature?
At TA = 100°C, derating from the 600mW PD rating (RθJA = 209°C/W) yields ~2.4A theoretical limit, but datasheet specifies −2A continuous rating across −55°C to +150°C junction range-so −2A remains the absolute maximum sustained current regardless of ambient, provided heatsinking meets minimum pad layout requirements.
Does DSS5220TQ support pulsed operation beyond its −2A continuous rating?
Yes. The device supports −3A peak pulse current (ICM) with pulse width ≤300µs and duty cycle ≤2%, as verified in pulsed electrical testing. This enables short-duration surge handling in motor startup or inductive load switching without thermal failure.
Can DSS5220TQ be used in linear regulator pass-transistor applications?
No. Its VCE(sat) specification and thermal design focus on switching operation-not linear regulation. The device lacks guaranteed safe operating area (SOA) curves for linear mode, and RCE(sat) is optimized for saturation, not variable VCE control. Use dedicated LDOs or linear pass transistors instead.
