Product details
Overview
PS9505L2-AX from Renesas Electronics is a surface-mount, gull-wing lead-bent 8-pin DIP photocopler optimized for IGBT gate driving in high-noise industrial inverters and induction heating systems. It delivers 2.5 A peak output current, achieves 0.25 μs max propagation delay (tPLH/tPHL), and provides ±25 kV/μs common-mode transient immunity with integrated UVLO protection.
For engineers reviewing the PS9505L2-AX datasheet, PS9505L2-AX pinout, PS9505L2-AX application, or PS9505L2-AX equivalent, key selection criteria include its long creepage distance (8 mm), Pb-free gull-wing SMT package, guaranteed 2.0 A min output current under 10 μs pulse width, and VDE option availability for reinforced isolation compliance.
Technical Context
The PS9505L2-AX integrates a GaAlAs LED input stage with a monolithic photo-diode, signal processor, and power output transistor on a single chip. Its dual-transistor output stage enables complementary high-side/low-side drive capability with fast switching and built-in UVLO hysteresis (1.3 V typical).
It operates across −40°C to +110°C ambient temperature with 15–30 V supply range (VCC–VEE), supports 50 kHz max operating frequency, and maintains stable performance under high dv/dt transients via internal shield and optimized layout-critical for IGBT gate control in motor drives and resonant converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Output Current | 2.5 A MAX / 2.0 A MIN - sufficient to directly drive 75 A/1200 V IGBTs without external buffers |
| Propagation Delay | tPLH/tPHL ≤ 0.25 μs - enables precise timing control in high-frequency PWM inverters |
| CM Transient Immunity | ±25 kV/μs MIN - suppresses false triggering during fast IGBT switching in noisy EMI environments |
| UVLO Threshold | VUVLO+ = 12.3 V TYP, hysteresis = 1.3 V - prevents erratic gate behavior during brown-out or startup |
| Creeage Distance | 8 mm MIN - meets reinforced insulation requirements for industrial mains-connected equipment |
| Isolation Voltage | 5000 Vrms - certified for basic and reinforced isolation per UL, CSA, SEMKO, and optional VDE 0884-2 |
| Package Type | 8-pin DIP gull-wing SMT - enables automated assembly while maintaining >8 mm creepage via lead bending |
Pinout & Package
PS9505L2-AX uses an 8-pin dual-in-line package with gull-wing surface-mount leads, designed for long creepage distance (8 mm) and RoHS-compliant Pb-free plating (Ni/Pd/Au). Dimensions: 9.25 × 6.5 × 11.8 mm (L×W×H), lead pitch 2.54 mm, gull-wing standoff 0.9 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection; must be left open or tied to GND on LED side - not usable as signal path |
| 2 | Anode | LED anode input - requires 7–16 mA forward current for reliable turn-on |
| 3 | Cathode | LED cathode - referenced to input-side ground; reverse voltage limited to 5 V |
| 4 | NC | No internal connection; same handling as Pin 1 |
| 5 | VEE | Output-stage emitter reference - typically connected to IGBT emitter or power ground |
| 6 | VO | High-side output terminal - sources up to 2.5 A to IGBT gate when active |
| 7 | VO | Low-side output terminal - sinks up to 2.5 A from IGBT gate when active |
| 8 | VCC | Positive supply for output stage - operates from 15–30 V relative to VEE |
Key Features
| Feature | Design Value |
|---|---|
| Long Creepage Distance | 8 mm minimum - satisfies reinforced insulation requirements for 300–600 VAC industrial systems |
| UVLO with Hysteresis | 12.3 V turn-on / 11.0 V turn-off - prevents oscillation during marginal supply conditions |
| High-Speed Switching | 0.25 μs max tPLH/tPHL - supports >1 MHz effective PWM resolution in digital gate drivers |
| EMI-Robust Output Stage | Dual NPN/PNP output transistors with internal shield - minimizes coupling between input and output under 1.5 kV CM transients |
| Pb-Free & Tape-Packed | Ni/Pd/Au plating; supplied in embossed tape (1000 pcs/reel) - compatible with standard SMT reflow profiles (260°C peak) |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar IGBT gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ACPL-332J-500E | Lower peak output (2.0 A), slower tPLH/tPHL (0.35 μs), no integrated UVLO - requires external monitoring circuit | Targeted at cost-sensitive 600 V IGBTs in lower-power inverters; lacks VDE option | Select when budget constraints outweigh need for 2.5 A drive strength or VDE certification |
| SI8261BBC-C-ISR | Digital isolator with MOSFET gate driver; higher CMTI (35 kV/μs), but 4 A peak only with external boost capacitor | Requires external gate resistor network and bootstrap components; better suited for SiC MOSFETs than IGBTs | Prefer for high-frequency SiC designs needing >1 MHz switching; avoid for legacy IGBT gate drive without redesign |
Compared with ACPL-332J-500E and SI8261BBC-C-ISR, PS9505L2-AX offers superior native IGBT drive capability (2.5 A, UVLO-integrated, 0.25 μs), certified long-creepage packaging, and plug-in compatibility with existing DIP-8 footprints - reducing BOM count and qualification effort in industrial inverter platforms.

FAQ
What is the maximum recommended reflow temperature for PS9505L2-AX?
The PS9505L2-AX supports infrared reflow soldering with a peak package surface temperature of 260°C or below for ≤10 seconds. Preheat time from 120°C to 180°C must be 120±30 s, and time above 220°C must not exceed 60 s. These conditions ensure reliability of the internal GaAlAs LED and bond wires without delamination or degradation.
Does PS9505L2-AX require external components for UVLO functionality?
No, PS9505L2-AX includes fully integrated UVLO with hysteresis (1.3 V typical) that activates automatically when VCC drops below 11.0 V and releases at 12.3 V. No external resistors, capacitors, or comparators are needed - simplifying design and improving gate drive reliability during brown-out events.
Can PS9505L2-AX drive both N-channel and P-channel IGBT gates?
PS9505L2-AX is configured as a dual-output, complementary driver: Pin 6 (VO) sources current for high-side turn-on, and Pin 7 (VO) sinks current for low-side turn-off. It is optimized for standard N-channel IGBTs in half-bridge configurations - not designed for direct P-channel gate control without external inversion circuitry.
What safety certifications does PS9505L2-AX hold?
PS9505L2-AX is UL approved (E72422), CSA certified (CA 101391), SEMKO approved (1115598), and optionally VDE 0884-2 certified (DIN EN60747-5-2, No. 40024069). All certifications cover 5000 Vrms isolation voltage and 8 mm creepage, validating its use in Class I and II industrial equipment.
How does the PS9505L2-AX differ from the PS9505L3-AX variant?
PS9505L2-AX features gull-wing leads optimized for long creepage distance (8 mm) in surface-mount applications, whereas PS9505L3-AX uses gull-wing leads without extended creepage (7 mm). Both share identical electrical specs and pinout, but PS9505L2-AX is required for designs needing reinforced insulation per IEC 61800-5-1 or UL 61800-5-1.
