Product details
Overview
PS9505L1-AX from Renesas Electronics is an 8-pin DIP photocopler optimized for IGBT gate driving, featuring 2.5 A peak output current, ±25 kV/μs common-mode transient immunity (CMTI), and UVLO protection with 1.3 V hysteresis. It integrates a GaAlAs LED input and a high-speed power output transistor on a single chip, designed for industrial inverters and induction heating systems requiring robust isolation and fast switching.
For engineers reviewing the PS9505L1-AX datasheet, PS9505L1-AX pinout, PS9505L1-AX application, or PS9505L1-AX equivalent, this device delivers verified high-CMR performance, long creepage distance (8 mm min), and precise threshold control-critical for reliable IGBT/MOSFET gate drive in high-noise motor control and power conversion designs.
Technical Context
The PS9505L1-AX uses optical coupling between a GaAlAs LED and a monolithic output stage containing signal processing circuitry and dual complementary power transistors. Its functional diagram confirms push-pull output topology with active high/low drivers and integrated shielded layout to suppress capacitive coupling.
UVLO operates with two thresholds: turn-on at 12.3 V (typ) and turn-off at 11.0 V (typ), providing 1.3 V hysteresis to prevent oscillation during supply ramp-up/down. Propagation delays are tightly controlled at tPLH ≤ 0.25 μs and tPHL ≤ 0.25 μs under 10 kHz, 50% duty cycle, with Rg = 10 Ω and Cg = 10 nF load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Output Current | 2.5 A max (10 μs pulse, 0.2% duty) - sufficient to drive 75 A/1200 V IGBTs without external boost stages |
| Common-Mode Transient Immunity | ±25 kV/μs min - ensures stable operation during fast dV/dt transients in inverter bridge legs |
| Propagation Delay | tPLH/tPHL ≤ 0.25 μs - enables >1 MHz effective switching control loop bandwidth in gate driver circuits |
| UVLO Threshold Hysteresis | 1.3 V typ - prevents false triggering during brown-out or soft-start sequences |
| Creepage Distance | 8 mm min - meets reinforced insulation requirements per UL, CSA, and VDE standards for industrial mains-connected systems |
| Isolation Voltage | 5000 Vr.m.s. - certified for 1-minute AC withstand between input and output, supporting safety-critical isolation |
| Operating Temperature | −40°C to +110°C - qualified for under-hood and industrial ambient environments without derating |
Pinout & Package
PS9505L1-AX uses an 8-pin DIP package with lead bending for extended creepage (8 mm). Pins 1 and 4 are NC (non-connected); pins 2 and 3 form the LED anode/cathode; pins 5 (VEE), 6–7 (VO), and 8 (VCC) constitute the output side with dual VO pins for current sharing and low-inductance routing.
| 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 or bypass |
| 2 | Anode | LED anode input - requires series resistor limiting IF to 7–16 mA per recommended operating conditions |
| 3 | Cathode | LED cathode return - connects to system GND or negative bias rail for reverse-bias protection |
| 4 | NC | No internal connection; same handling as Pin 1 - avoids noise coupling into sensitive input side |
| 5 | VEE | Negative output supply reference - typically GND; sets lower rail for output transistor emitter/source |
| 6, 7 | VO | Output voltage terminals - paralleled to deliver full 2.5 A peak; low-impedance path for gate discharge |
| 8 | VCC | Positive output supply - 15–30 V range supports standard IGBT gate drive voltages with margin |
Key Features
| Feature | Design Value |
|---|---|
| Long Creepage Distance | 8 mm minimum - enables compliance with reinforced insulation requirements in 600–1000 VAC industrial systems |
| UVLO with Hysteresis | 12.3 V turn-on / 11.0 V turn-off (typ) - eliminates chatter during undervoltage events in unregulated DC bus applications |
| High-Speed Switching | tPLH/tPHL ≤ 0.25 μs - reduces dead-time uncertainty and improves inverter efficiency at high PWM frequencies |
| Pb-Free Construction | Ni/Pd/Au plating - RoHS-compliant and compatible with lead-free reflow profiles up to 260°C peak |
| Safety Certifications | UL E72422, CSA CA101391, SEMKO 1115598, VDE0884 Option - validated for global industrial equipment approvals |
Applications
| Industrial Inverter Motor Control | Induction Heating (IH) Systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar IGBT gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP350(D,F) | Lower peak output (1.5 A), no UVLO, 8-pin DIP but 7 mm creepage | Limited to <1200 V systems; requires external UVLO circuitry | Choose when cost sensitivity outweighs need for integrated protection and higher CMTI |
| ACPL-332J | 2.5 A peak, 5 kVr.m.s. isolation, but only 15 kV/μs CMTI and 0.5 μs max delay | Suitable for lower-noise 400 VAC systems; lacks long creepage certification | Select for space-constrained designs needing SOIC-8 surface mount, not DIP through-hole |
Compared with TLP350(D,F) and ACPL-332J, PS9505L1-AX provides superior noise immunity (±25 kV/μs), integrated UVLO with hysteresis, and certified 8 mm creepage-making it the preferred choice for high-reliability, high-voltage industrial inverters where safety and timing precision are non-negotiable.

FAQ
What is the maximum recommended forward current for the PS9505L1-AX LED input?
The PS9505L1-AX LED input has a recommended forward current range of 7–16 mA, with absolute maximum rating of 25 mA continuous and 1.0 A peak (pulse width < 1 μs). Operating within 7–16 mA ensures optimal CTR stability, lifetime reliability, and consistent switching performance across temperature. Exceeding 16 mA continuously may accelerate LED degradation and reduce isolation lifetime.
Does PS9505L1-AX support both high-side and low-side IGBT gate driving configurations?
Yes, PS9505L1-AX supports both configurations via its push-pull output architecture: VO pins source current for high-side turn-on and sink current for low-side turn-off. Its VEE-referenced output stage allows direct connection to either emitter (low-side) or collector (high-side, with floating supply) topologies. The dual VO pins (6 and 7) must be paralleled to handle full 2.5 A peak current in either configuration.
How does the UVLO function behave during power-up of PS9505L1-AX?
During power-up, PS9505L1-AX remains in output disable state until VCC reaches 12.3 V (typ), at which point the output stage activates. If VCC subsequently drops below 11.0 V (typ), the output disables again. This 1.3 V hysteresis prevents oscillation near the threshold. The UVLO turn-on delay is 0.8 μs (typ), ensuring stable enablement after supply stabilization.
Can Pins 1 and 4 of PS9505L1-AX be used for grounding or signal routing?
No - Pins 1 and 4 are explicitly designated NC (non-connected) in the PS9505L1-AX datasheet. They have no internal connection and must remain unconnected or tied to GND on the LED side only. Using them for signal routing, bypass, or shielding degrades internal noise immunity and violates design guidelines, potentially causing malfunction or reduced CMTI performance.
What is the significance of the "L1" suffix in PS9505L1-AX?
The "L1" suffix identifies the lead-bending DIP variant optimized for long creepage distance (8 mm minimum), distinguishing it from PS9505 (standard DIP), PS9505L2 (gull-wing SMT, long creepage), and PS9505L3 (gull-wing SMT, standard creepage). PS9505L1-AX is through-hole mounted with bent leads to maximize air gap and surface tracking distance - critical for UL/CSA/VDE reinforced insulation compliance in high-voltage industrial equipment.
