Product details
Overview
AL5890-10P1-13 from Diodes Incorporated is a 400V constant-current linear LED driver in PowerDI®123 (Type B) package, delivering a factory-trimmed 10mA output with ±2.0mA (typ.) accuracy over −40°C to +105°C ambient, supporting high-side or low-side LED string configuration up to 400V, and featuring thermal foldback protection triggered at +130°C junction temperature for commercial lighting and emergency signage.
For engineers reviewing the AL5890-10P1-13 datasheet, AL5890-10P1-13 pinout, AL5890-10P1-13 application, or AL5890-10P1-13 equivalent, this part enables rapid implementation of thermally robust, resistorless LED current regulation in space-constrained AC/DC lighting fixtures where stable single-digit mA drive and wide input voltage range are required.
Technical Context
The AL5890-10P1-13 integrates a bandgap reference, voltage regulator, and current-sense circuit to maintain precise 10mA LED current across 7–400V input-to-output differential voltage. Its linear topology eliminates switching noise but requires thermal management via the exposed pad of the PowerDI123 (Type B) package.
It operates as a two-terminal current source with no external components needed-turn-on occurs when VIN−OUT exceeds 7V, and thermal foldback begins at TJ = +130°C, reducing output current linearly to limit power dissipation without shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 10mA ±1.0mA (min/max at +25°C), trimmed at production for resistorless operation |
| Operating Voltage Range | 7V to 400V VIN−OUT differential-supports long LED strings up to ~120 white LEDs (3.3V each) in series |
| Current Accuracy | < ±2.0mA (typ.) over −40°C to +105°C ambient-enables consistent luminance across temperature extremes |
| Thermal Foldback Threshold | +130°C junction temperature-prevents thermal runaway by linearly scaling down current above threshold |
| Turn-On Delay | ≤6µs-ensures fast response in dynamic dimming or strobe applications |
| Junction Temperature Range | −40°C to +125°C-validates operation in enclosed outdoor or industrial enclosures |
| ESD Rating (HBM) | 2000V-meets IEC 61000-4-2 Level 2 for handling in automated assembly lines |
Pinout & Package
AL5890-10P1-13 uses the PowerDI®123 (Type B) package-a thermally enhanced 3-pin surface-mount outline with an exposed thermal pad on the bottom side (not electrically connected). The package measures 3.70mm × 2.80mm × 1.78mm and supports 1.33W continuous power dissipation at TA = +25°C with standard PCB layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| In | LED current input terminal | Connects to positive supply (high-side) or cathode return (low-side); must sustain up to 400V transient |
| Out | LED current output terminal | Connects to LED anode (high-side) or negative rail (low-side); forms current loop with IN pin |
| NC | No connect | Pin 3 is internally unconnected-must remain floating; not used for thermal relief or grounding |
Key Features
| Feature | Design Value |
|---|---|
| Pre-set 10mA output | Eliminates external current-setting resistor, reducing BOM count and layout area in compact lighting modules |
| 400V operating voltage | Enables direct connection to rectified 277VAC line (≈390V peak) without pre-regulation, simplifying driver architecture |
| Thermal foldback protection | Self-adaptive current reduction prevents catastrophic failure during sustained overtemperature-no external sensor or control logic needed |
| High-side / low-side flexibility | Supports both configurations without re-design-allows optimal placement relative to heat sinks, EMI filters, or safety isolation barriers |
| Lead-free & halogen-free | Complies with RoHS 3 (2015/863/EU) and Diodes' "Green" definition (<900ppm Br/Cl, <1000ppm Sb)-suitable for eco-certified fixtures |
Applications
| Commercial LED Downlights | Emergency Exit Signage |
|---|---|
Use Scenario: Indoor recessed downlight operating from 277VAC line with 24–36 white LEDs in series. IC Role / Device Role: High-side constant-current regulator providing stable 10mA drive independent of line fluctuations. Use Value: Maintains uniform brightness across fixture lifetime and ambient temperatures from 0°C to 45°C without current drift or thermal shutdown. |
Use Scenario: Battery-backed exit sign with dual LED strings powered from 12V DC backup and 120/277VAC main supply. IC Role / Device Role: Low-side current regulator enabling shared current control across AC and DC paths using single component. Use Value: Ensures identical luminance and color point between AC and DC modes, critical for NFPA 101 compliance. |
| Architectural Accent Lighting | Decorative LED Strips |
Use Scenario: Linear aluminum extrusion housing 40–60 warm-white LEDs driven from 240VAC rectified bus. IC Role / Device Role: High-side current source placed adjacent to LED string to minimize trace inductance and EMI. Use Value: Delivers flicker-free illumination with <±2% current variation across 0–45°C ambient-no visible intensity shift under thermal cycling. |
Use Scenario: Flexible PCB-based decorative strip with segmented 10–15 LED sections powered from 120VAC-derived DC bus. IC Role / Device Role: Low-side current regulator per segment, enabling independent current tuning via part number selection (10/15/20mA variants). Use Value: Enables precise lumen matching across segments without trimming resistors-reducing calibration time and test cost. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar constant-current LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AL5809-10P1-13 | Same 10mA output but lower 200V max VIN−OUT rating; no thermal foldback | Limited to ≤60-LED strings on 120VAC-derived supplies; unsuitable for 277VAC or high-ambient installations | Select only for cost-sensitive, low-voltage (<200V), thermally benign indoor applications |
| NSI45015T1R2G | 15mA fixed output, 45V max VIN−OUT, SOD-123 package, no thermal foldback | Requires pre-regulation for >45V systems; lacks overtemperature protection; smaller thermal mass | Use only in low-power indicator or status-light designs with active thermal monitoring |
Compared with AL5809-10P1-13 and NSI45015T1R2G, the AL5890-10P1-13 uniquely combines 400V operation, integrated thermal foldback, and resistorless 10mA accuracy-making it the sole choice for self-contained, maintenance-free LED drivers in high-line-voltage commercial fixtures.

FAQ
What is the minimum input-to-output voltage required for AL5890-10P1-13 to regulate?
The AL5890-10P1-13 requires a minimum VIN−OUT differential of 7V to begin regulating current. Below this threshold, the device remains off and draws negligible current. This ensures reliable turn-on even with aging electrolytic capacitors or brown-out conditions in AC-driven lighting systems.
Can AL5890-10P1-13 be used in high-side and low-side configurations interchangeably?
Yes-the AL5890-10P1-13 functions identically in both high-side and low-side topologies. In high-side mode, IN connects to the positive rail and OUT to the LED anode; in low-side mode, IN connects to the LED cathode and OUT to ground. No external changes are needed.
How does thermal foldback affect LED brightness in sustained high-temperature operation?
When junction temperature exceeds +130°C, AL5890-10P1-13 linearly reduces output current-e.g., at +140°C, current drops ~10%-to limit power dissipation. This preserves LED lifetime and avoids abrupt shutdown, maintaining visible (though dimmed) illumination during thermal overload.
Is AL5890-10P1-13 compatible with PWM dimming?
No-the AL5890-10P1-13 is a linear constant-current regulator without enable or dimming pins. It cannot be directly PWM-dimmed. For dimming, use analog current adjustment via external bias or pair with a separate PWM-controlled switch upstream of the driver.
