Product details
Overview
PS9308L2-AX from Renesas Electronics is a 6-pin SDIP surface-mount photocopler optimized for IGBT and power MOSFET gate driving in high-noise industrial inverters and induction heating systems. It delivers 2.0 A peak output current, achieves ≤0.25 μs propagation delay (tPLH/tPHL), and provides ±25 kV/μs common-mode transient immunity with 8 mm minimum creepage distance.
For engineers reviewing the PS9308L2-AX datasheet, PS9308L2-AX pinout, PS9308L2-AX application, or PS9308L2-AX equivalent, this device is selected for high-CMR isolated gate drive where UVLO protection, fast switching, and long creepage compliance to UL/CSA/SEMKO/VDE standards are required in motor drives and power conversion designs.
Technical Context
The PS9308L2-AX integrates a GaAlAs LED input stage with a monolithic photo-diode, signal processing circuit, and high-current power output transistor on a single chip. Its architecture enables direct drive of IGBT gates without external amplification while maintaining galvanic isolation up to 5,000 Vr.m.s.
It implements under-voltage lockout (UVLO) with hysteresis (VUVLO+ = 12.3 V typ., VUVLO− = 11.0 V typ.) and supports supply voltages from 15 V to 30 V (VCC–VEE). The output stage operates in push-pull configuration with VO referenced to VEE and VCC, enabling both high-side and low-side gate control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Output Current | 2.0 A MAX. - sufficient to charge/discharge large IGBT gate capacitances rapidly |
| Propagation Delay | ≤0.25 μs (tPLH/tPHL) - enables >1 MHz switching in hard-switched topologies |
| CM Transient Immunity | ±25 kV/μs MIN. - suppresses false triggering in high-dv/dt motor drive environments |
| Creepage Distance | 8 mm MIN. - meets reinforced insulation requirements per UL/CSA/EN 60950 and VDE 0884-5 |
| UVLO Threshold | VUVLO+ = 12.3 V typ., hysteresis = 1.3 V MAX. - prevents erratic gate behavior during brown-out conditions |
| Isolation Voltage | 5,000 Vr.m.s for 1 minute - certified barrier for functional safety in industrial equipment |
| Operating Temperature | −40°C to +110°C - supports deployment in enclosed inverters and induction cooktops |
Pinout & Package
PS9308L2-AX uses a 6-pin Shrink Dual In-line Package (SDIP) with gull-wing leads for surface mounting. Package dimensions: 11.5 mm × 6.8 mm × 4.58 mm (L×W×H), 0.25 mm lead thickness, 1.27 mm lead pitch, and 8 mm minimum outer creepage distance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | LED anode input | Forward bias connection for GaAlAs LED; requires series resistor to limit IF to 7–16 mA |
| 2 (NC) | No Connection | Internally unconnected; must be left floating or tied to GND on input side - not usable as signal path |
| 3 (Cathode) | LED cathode input | Return path for LED current; referenced to input-side ground (VEE) |
| 4 (VEE) | Output emitter reference | Low-side output return; establishes reference for IOL and VOL measurements |
| 5 (VO) | Output driver terminal | High-current open-collector output node; connects directly to IGBT gate for turn-on/turn-off |
| 6 (VCC) | Output supply rail | Positive supply for output stage; sets VO swing range (0 to VCC) and enables IOH sourcing |
Key Features
| Feature | Design Value |
|---|---|
| Long creepage distance | 8 mm MIN. - satisfies reinforced insulation requirements for 300–600 V AC mains-connected inverters |
| High-speed switching | tPLH/tPHL ≤ 0.25 μs - reduces dead-time uncertainty and improves inverter efficiency at 20–50 kHz |
| UVLO with hysteresis | VUVLO+/VUVLO− = 12.3 V / 11.0 V typ. - ensures clean power-up/power-down sequencing without oscillation |
| High CMR | ±25 kV/μs - maintains logic integrity when driving IGBTs switching 1,200 V bus with >5 kV/μs transients |
| Pb-Free construction | RoHS-compliant Ni/Pd/Au plating - meets environmental compliance for global industrial equipment shipments |

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-000E | SO-6 package, 2.5 A peak output, tPLH/tPHL = 0.2 μs MAX., 5 mm creepage | Limited to lower insulation requirements (UL/CSA only); unsuitable where 8 mm creepage or VDE 0884-5 is mandated | Select when higher peak current and faster timing are prioritized over reinforced creepage in non-safety-critical PFC stages |
| SI8233AD-D-IS | Dual-channel isolated driver, 4 A peak per channel, 30 kV/μs CMTI, SOIC-16 package | Requires external level-shifting for high-side gate drive; no integrated UVLO - needs external monitoring circuit | Choose for dual-gate drive in half-bridge configurations where independent channel control and higher CMTI outweigh single-channel simplicity |
Compared with ACPL-332J-000E and SI8233AD-D-IS, PS9308L2-AX offers certified 8 mm creepage and integrated UVLO in a compact SDIP footprint - making it optimal for space-constrained, safety-certified IGBT drivers where single-channel simplicity and robust isolation are essential.

FAQ
What is the maximum recommended forward current for the PS9308L2-AX LED input?
The PS9308L2-AX LED has a recommended forward current (IF) range of 7–16 mA per the datasheet's Recommended Operating Conditions. Absolute maximum continuous forward current is 25 mA, but sustained operation above 16 mA may accelerate LED degradation and reduce isolation lifetime. For reliable 10+ year operation in industrial environments, design to 10 mA nominal with appropriate series resistance.
Does PS9308L2-AX support both high-side and low-side IGBT gate driving?
Yes, PS9308L2-AX supports both configurations. Its VO output is referenced between VEE (pin 4) and VCC (pin 6), allowing it to source current (IOH) when VO is pulled toward VCC for high-side turn-on, or sink current (IOL) when VO is pulled toward VEE for low-side turn-on. The output stage is designed for direct connection to IGBT gates without polarity reversal.
What safety certifications apply to PS9308L2-AX?
PS9308L2-AX is UL approved (E72422), CSA approved (CA 101391), SEMKO approved (EN 60065/EN 60950), and optionally VDE 0884-5 certified (DIN EN 60747-5-5). The 8 mm creepage distance and 5,000 Vr.m.s isolation voltage meet reinforced insulation requirements for industrial equipment operating up to 600 V AC mains.
How does the UVLO function protect the IGBT when using PS9308L2-AX?
The PS9308L2-AX UVLO monitors VCC–VEE and disables the output stage if the supply drops below VUVLO− (11.0 V typ.). When VCC rises above VUVLO+ (12.3 V typ.), output resumes - with 1.3 V hysteresis preventing chatter near threshold. This prevents partial turn-on of the IGBT, which could cause thermal runaway or shoot-through in bridge configurations.
Can Pin 2 (NC) on PS9308L2-AX be used as a ground connection?
Pin 2 is explicitly designated NC (No Connection) and is internally unconnected. The datasheet permits tying it to GND on the input side *only* - never to output-side grounds or signal paths. Doing so avoids unintended coupling paths that could degrade CMR performance. It must never be used as a bypass capacitor node or signal return.
