Product details
Overview
2DD1664R-13 from Diodes Incorporated is a 32V NPN surface-mount transistor in SOT89 package, rated for 1A continuous collector current and 40V collector-base breakdown voltage, with hFE of 180–390 at IC = 100mA/VCE = 3V, used in medium-power switching and amplification circuits such as DC-DC converter control stages and automotive load drivers.
For engineers reviewing the 2DD1664R-13 datasheet, 2DD1664R-13 pinout, 2DD1664R-13 application, or 2DD1664R-13 equivalent, key selection criteria include VCEO = 32V, IC = 1A, hFE range, thermal resistance (RθJC = 18°C/W), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This NPN bipolar junction transistor employs epitaxial planar die construction for stable gain and low leakage, with complementary PNP type 2DB1132 available for push-pull configurations. Its SOT89 package features an exposed collector pad for enhanced thermal dissipation.
Rated for operation from –55°C to +150°C, it supports pulsed switching up to 2A peak current and delivers fT = 280MHz at IE = 50mA/VCE = 5V, enabling use in medium-frequency amplifier and switch-mode driver applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 32 V - Maximum safe collector-emitter voltage before breakdown under open-base conditions. |
| IC (continuous) | 1 A - Continuous collector current rating defining maximum steady-state power switching capability. |
| hFE | 180–390 - DC current gain range at IC = 100mA/VCE = 3V, critical for base drive sizing in linear or saturated switching. |
| VCE(SAT) | 120–400 mV - Saturation voltage at IC = 500mA/IB = 50mA, directly impacting conduction loss in switch applications. |
| fT | 280 MHz - Transition frequency indicating usable bandwidth for small-signal amplification or high-speed switching. |
| RθJC | 18 °C/W - Junction-to-case thermal resistance, enabling thermal design when mounting the exposed collector pad to PCB copper. |
| AEC-Q101 | Qualified - Meets stress-test requirements for automotive electronics, including temperature cycling and HBM ESD (4 kV). |
Pinout & Package
SOT89 package with molded plastic case, UL 94V-0 flammability rating, matte tin terminals, and exposed collector pad for thermal management. Weight: 0.055 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Collector (C) | Main current-carrying terminal, connected to exposed metal tab | Primary heat path to PCB; must be soldered to ≥15 mm² 1 oz copper for rated 1 W power dissipation. |
| Emitter (E) | Current return path, common reference for base drive | Low-impedance output node in emitter-follower or grounded-emitter configurations. |
| Base (B) | Control input for bipolar current amplification | Requires current-limited drive (e.g., 50 mA typical for 500 mA IC) to ensure saturation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood applications including engine control modules and body electronics. |
| Exposed collector pad | Enables RθJC = 18°C/W, supporting 1 W continuous dissipation with minimal PCB copper area. |
| High hFE bin (R-grade) | Guaranteed 180–390 gain ensures consistent base drive requirements across production lots. |
| Green, halogen-free construction | Meets RoHS 3 (2015/863/EU) and Diodes' "Green" standard (<900 ppm Br/Cl, <1000 ppm Sb). |
| ESD robustness | HBM rating of 4 kV allows handling in standard assembly environments without special precautions. |
Applications
| Automotive Lighting Control | DC-DC Converter Switch Driver |
|---|---|
Use Scenario: Driving LED headlamp arrays or relay coils in vehicle body control modules. IC Role / Device Role / Timing Role: Medium-power NPN switch controlling 500–800 mA loads with PWM dimming or on/off sequencing. Use Value: VCEO = 32V withstands automotive load-dump transients; hFE ≥ 180 reduces base drive burden on microcontroller GPIO. |
Use Scenario: Active switch in buck converter topologies for 12 V to 5 V/3.3 V point-of-load regulation. IC Role / Device Role / Timing Role: Saturated switch operating at ≤200 kHz, driven by gate driver or controller PWM output. Use Value: VCE(SAT) ≤ 400 mV limits conduction loss; RθJC = 18°C/W enables thermal stability without heatsink. |
| Industrial Sensor Interface | Power Supply Enable Circuit |
Use Scenario: Amplifying low-level analog signals from pressure or temperature sensors before ADC sampling. IC Role / Device Role / Timing Role: Common-emitter amplifier stage with fixed bias network and emitter degeneration. Use Value: fT = 280 MHz supports bandwidth >10 MHz for fast transient response; low ICBO ≤ 100 nA minimizes offset drift. |
Use Scenario: Enabling/disabling auxiliary rails (e.g., USB VBUS, display backlight) via MCU-controlled logic signal. IC Role / Device Role / Timing Role: High-side or low-side enable switch with fast turn-on/turn-off controlled by digital output. Use Value: ton/toff < 100 ns (typical) ensures clean rail sequencing; AEC-Q101 ensures reliability in industrial control panels. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN medium-power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MJD127G | Higher VCEO = 100V, lower hFE = 30–120, TO-252 package | Better suited for higher-voltage industrial motor drives; less suitable for space-constrained automotive PCBs | Select when >60V blocking is required and thermal mass permits larger footprint. |
| ZTX653 | Same SOT89 package, VCEO = 30V, hFE = 200–450, but not AEC-Q101 qualified | Acceptable for commercial-grade consumer power supplies, not automotive systems | Choose only for cost-sensitive non-automotive designs where qualification is not mandated. |
Compared with MJD127G and ZTX653, the 2DD1664R-13 uniquely balances AEC-Q101 compliance, SOT89 form factor, and high-gain bin-making it optimal for space- and reliability-constrained automotive and industrial switching where 32V blocking suffices.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The 2DD1664R-13 has an operating junction temperature range of –55°C to +150°C. For continuous operation at full 1 A collector current, thermal design must ensure TJ remains ≤150°C-achievable with ≥50 mm² 1 oz copper per the datasheet's derating curve and RθJA = 60°C/W condition.
Is the SOT89 footprint compatible with standard reflow profiles?
Yes-the SOT89 package uses matte tin terminations and complies with J-STD-020 moisture sensitivity level 1, allowing standard Pb-free reflow profiles (peak 260°C) without pre-bake. The exposed collector pad requires adequate stencil aperture and solder paste volume to ensure void-free thermal attachment.
How does the hFE binning differ between 2DD1664P/Q/R variants?
The 2DD1664P (hFE = 82–180), Q (120–270), and R (180–390) grades are binned at IC = 100mA/VCE = 3V. The R-grade guarantees minimum hFE = 180, reducing base drive variability in production designs where consistent saturation is essential.
Can this transistor replace a MOSFET in low-side switching applications?
No-it is a bipolar transistor requiring continuous base current to maintain saturation, unlike MOSFETs that need only gate charge. For low-side switching above ~100 kHz or where drive power efficiency matters, a MOSFET is preferred; the 2DD1664R-13 excels in DC or low-frequency (<50 kHz) applications with simple BJT drive circuitry.
