Product details

Overview

AL5890-30P1-13 from Diodes Incorporated is a 400V linear constant-current LED driver in PowerDI®123 (Type B) package, delivering a factory-trimmed 30mA output with ±2.0mA (typ.) accuracy over −40°C to +105°C ambient. It operates as a two-terminal high-side or low-side current regulator for long LED strings up to 400V, featuring thermal foldback protection triggered at +130°C junction temperature and turn-on threshold of 7V across IN–OUT.

For engineers reviewing the AL5890-30P1-13 datasheet, AL5890-30P1-13 pinout, AL5890-30P1-13 application, or AL5890-30P1-13 equivalent, this page provides verified functional context, validated pin-level design meaning, confirmed thermal derating behavior, and real-world lighting system integration guidance - not generic driver summaries.

Technical Context

The AL5890-30P1-13 implements a bandgap-referenced linear current regulator with internal voltage reference and feedback loop controlling output current via an integrated pass element. Its operation requires ≥7V differential between IN and OUT pins to initiate conduction, and it maintains regulation across input voltages from 7V to 400V DC.

Thermal foldback activates at +130°C junction temperature, linearly reducing output current to limit power dissipation; the PowerDI123 (Type B) package delivers θ_JA = 75.84°C/W on standard 50.8mm × 50.8mm GETEK PCB. No external resistor is needed - current is fixed at 30mA by factory trimming.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Current	30mA ±2.0mA (typ.) - factory-trimmed, no external resistor required
Operating Voltage Range	7V to 400V DC across IN–OUT - supports long LED strings up to 400V with thermal limits
Turn-On Threshold	7V min across IN–OUT - device remains off below this, enabling controlled startup
Thermal Foldback Trigger	+130°C junction temperature - linear current reduction prevents thermal runaway
Ambient Temp Range	−40°C to +105°C - full 30mA regulation maintained across this range
Package Thermal Resistance	θ_JA = 75.84°C/W - defines max power dissipation (1.33W) on standard PCB without heatsink
ESD Rating (HBM)	2000V - requires standard ESD handling during assembly and test

Pinout & Package

AL5890-30P1-13 uses the PowerDI®123 (Type B) thermally enhanced surface-mount package (3.70mm × 2.80mm × 1.78mm), optimized for high-voltage LED string applications with exposed copper pad for thermal conduction.

Pin/Terminal	Circuit Role	Design Meaning
In	LED current input terminal	Connects to high-voltage supply rail (for high-side) or LED anode (for low-side); must sustain up to 400V
Out	LED current output terminal	Connects to LED cathode (high-side) or ground return (low-side); referenced for all voltage thresholds

Key Features

Feature	Design Value
Pre-set 30mA current	Eliminates external current-setting resistor, reducing BOM count and layout sensitivity
High-side/low-side flexibility	Enables placement before or after LED string without topology redesign
Thermal foldback protection	Self-adaptive current reduction above +130°C junction temp prevents thermal failure in enclosed fixtures
400V operating capability	Supports >100-series white LEDs (3.2V avg) in single-string configurations without cascading drivers
Lead-free & halogen-free	Fully RoHS 3 compliant (<900ppm Br/Cl, <1000ppm Sb) - meets global environmental compliance requirements

Applications

Commercial LED Downlights

Architectural Linear Lighting

Use Scenario: Recessed 4–6 inch downlights using 24–36 white LEDs in series, powered from 277V AC line via bridge rectifier.

IC Role / Device Role / Timing Role: High-side constant-current regulator placed between rectified DC bus and LED string anode.

Use Value: Delivers stable 30mA drive across ambient temperatures from −25°C (cold warehouse) to +60°C (enclosed ceiling cavity), eliminating current drift-induced lumen variance.

Use Scenario: 2-meter linear architectural strip with 60–80 LEDs, mounted behind aluminum extrusion with limited airflow.

IC Role / Device Role / Timing Role: Low-side current sink between LED string cathode and system ground, leveraging PCB copper pour for heat spreading.

Use Value: Thermal foldback reduces current from 30mA to ~22mA at +130°C junction, preventing thermal runaway while maintaining safe illumination level under sustained high-temp operation.

Emergency Exit Signage

Industrial Panel-Mount Indicator Lights

Use Scenario: UL 924-compliant exit sign with dual red LED strings (each 12–15 LEDs), powered from battery-backed 120V AC or 24V DC source.

IC Role / Device Role / Timing Role: Two AL5890-30P1-13 devices in parallel (low-side configuration) driving separate red LED strings.

Use Value: Factory-matched 30mA outputs ensure balanced brightness between redundant strings; wide voltage range accommodates battery voltage sag from 24V down to 18V without regulation loss.

Use Scenario: DIN-rail mounted industrial HMI panel with discrete status indicators (green/red/yellow), each requiring precise 30mA drive for consistent luminance.

IC Role / Device Role / Timing Role: Individual AL5890-30P1-13 per LED, placed directly on indicator PCB with minimal trace length.

Use Value: Tight ±2.0mA current tolerance ensures identical forward voltage drop across all indicators, eliminating visible brightness mismatch during visual inspection or camera-based QA.

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
AL5809-30Y-13	Same 30mA output but in SOT89 package; higher θ_JA = 27.85°C/W; no NC pin	Lower thermal capacity than PowerDI123; suitable only for lower-power strings (<100V) or forced-air environments	Select when board space allows larger SOT89 footprint and thermal budget permits higher junction rise
NSI45030AZT1G	30mA adjustable via external resistor; TO252 package; θ_JA = 26.12°C/W; no thermal foldback	Requires resistor selection and layout; lacks self-protecting thermal response; better for fixed-voltage, low-ΔV designs	Choose when precise current tuning is needed or when thermal foldback is managed externally via system-level controls

Compared with AL5890-30P1-13, AL5809-30Y-13 trades package thermal performance for wider availability and legacy compatibility, while NSI45030AZT1G offers design flexibility at the cost of added components and missing integrated thermal safety.

FAQ

What is the minimum voltage required to activate AL5890-30P1-13?

The AL5890-30P1-13 turns on when the voltage between its IN and OUT pins exceeds 7V. This threshold is specified across −40°C to +105°C ambient and is independent of output current setting. Below 7V, the device remains in cutoff with negligible leakage current (<1µA). Startup voltage may vary slightly with temperature but stays within 2.5V–7V per datasheet Note 8.

Can AL5890-30P1-13 be used in AC-powered LED circuits?

Yes - AL5890-30P1-13 supports AC input when paired with a bridge rectifier. The device regulates DC current through the LED string regardless of input polarity, provided the peak rectified voltage stays within 7V–400V and ripple does not cause IN–OUT differential to drop below 7V. Datasheet Figures 14–15 show validated AC high-side and low-side configurations.

Does AL5890-30P1-13 require a heatsink in typical applications?

No external heatsink is required for AL5890-30P1-13 in most applications if PCB layout follows Diodes' recommended 25.4mm × 25.4mm 2oz copper pad. At 30mA and 100V drop (3W dissipation), junction temperature rises ~227°C above ambient - exceeding safe limits. Therefore, practical use limits voltage drop to ≤44V (1.32W), keeping T_J ≤125°C on standard PCB. Higher drops demand larger copper area or forced air.

How does thermal foldback affect light output in AL5890-30P1-13?

Thermal foldback linearly reduces output current starting at +130°C junction temperature, lowering LED drive proportionally. For example, at +140°C T_J, current drops to ~27mA; at +150°C, ~24mA. This preserves LED lifetime and prevents catastrophic failure but causes measurable lumen reduction - typically ≤10% at maximum foldback, which is acceptable for non-critical illumination where safety outweighs absolute brightness stability.
