Product details
Overview
PS9307AL2-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 AC servo systems. It delivers 0.6 A peak output current, achieves ≤150 ns propagation delay (tPLH/tPHL), and sustains ±50 kV/µs common-mode transient immunity at 125 °C ambient operation.
For engineers reviewing the PS9307AL2-AX datasheet, PS9307AL2-AX pinout, PS9307AL2-AX application, or PS9307AL2-AX equivalent, this device is selected for high-CMR isolated gate drive where creepage ≥8 mm, UVLO protection (8.6–9.8 V), and fast switching with reinforced insulation (UL1577, EN 62368-1) are mandatory.
Technical Context
The PS9307AL2-AX integrates an AlGaAs LED input stage with a monolithic output stage comprising a photodiode, signal processing circuit, and dual power MOSFETs - enabling single-chip, high-speed, high-current gate drive without external driver transistors. Its architecture supports direct connection to IGBT gates with integrated under-voltage lockout (UVLO) and robust noise rejection.
Designed for surface mounting with gull-wing leads, it features 8 mm minimum creepage distance and reinforced insulation per UL, CSA, SEMKO, and optional VDE DIN EN 60747-5-5 standards. The 6-pin SDIP package occupies half the footprint of legacy 8-pin DIP while maintaining isolation integrity up to 5,000 Vr.m.s..
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Output Current | 0.6 A MAX - sufficient to rapidly charge/discharge IGBT gates up to 1.5 µF at 250 kHz switching frequency |
| Propagation Delay | ≤150 ns (tPLH/tPHL) - enables precise timing control in high-frequency motor drives and inverters |
| CMR | ±50 kV/µs MIN - suppresses false triggering in high-dv/dt environments like VFDs and servo amplifiers |
| UVLO Threshold | 8.6–9.8 V (rising), 6.8–8.2 V (falling) - prevents IGBT turn-on during insufficient supply voltage, avoiding shoot-through |
| Isolation Voltage | 5,000 Vr.m.s. - certified reinforced insulation for safety-critical industrial equipment per UL1577 and EN 62368-1 |
| Operating Temperature | −40 to +125 °C - supports deployment in enclosed motor control cabinets without derating |
| Creepe Distance | 8 mm MIN - meets IPC-2221B Class B requirements for pollution degree 2, enabling compact PCB layout |
Pinout & Package
PS9307AL2-AX uses a 6-pin Shrink Dual In-line Package (SDIP) with gull-wing surface-mount leads and 8 mm minimum creepage distance. Package dimensions: 11.5 × 6.8 × 4.58 mm (L × W × H), weight 0.27 g (typ.), lead pitch 1.27 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1. Anode | LED input anode | Connects to current-limited logic or microcontroller GPIO; requires IF = 8–12 mA for reliable turn-on |
| 2. NC | No Connection | Must be left floating or tied to GND on input side; not usable as signal path or bypass node |
| 3. Cathode | LED input cathode | Completes LED forward path; reverse voltage rating is only 5 V - avoid accidental polarity reversal |
| 4. GND | Output-side ground reference | Return path for VO and VCC; must be low-inductance connection to minimize switching noise coupling |
| 5. VO | Output driver source terminal | High-side output pin - connects directly to IGBT gate; capable of sourcing 0.6 A peak into capacitive load |
| 6. VCC | Output-side supply rail | Accepts 10–30 V; powers internal MOSFETs and UVLO circuit - requires ≥1.0 µF local bypass within 10 mm |
Key Features
| Feature | Design Value |
|---|---|
| Reinforced insulation | UL1577 double protection, EN 62368-1, and optional VDE DIN EN 60747-5-5 certification - eliminates need for external isolation barriers in safety-rated designs |
| Integrated UVLO | Hysteresis of 0.4 V between 8.6 V (enable) and 6.8 V (disable) - ensures clean gate drive enable/disable without oscillation during brown-out |
| High-speed switching | 100 ns typical tPLH/tPHL with 5 ns typical pulse width distortion - preserves PWM fidelity in 20–100 kHz motor control loops |
| Pb-free construction | Ni/Pd/Au solder plating - compliant with RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) |
| Thermal robustness | Rated for continuous operation at +125 °C ambient - supports placement near power modules without forced cooling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar IGBT gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Toshiba TLP3547 | 0.5 A peak output, 100 ns max tPLH/tPHL, 7 mm creepage, no integrated UVLO | Lacks UVLO and has lower creepage - requires external UVLO circuit and larger PCB spacing for same safety rating | Select when cost sensitivity outweighs safety certification burden and thermal margin is ample |
| IXYS IX3407S | 0.6 A peak output, 125 ns max tPLH/tPHL, 8 mm creepage, UVLO threshold 12–14 V (higher activation voltage) | Higher UVLO threshold limits use with 12 V supplies; compatible with same 6-pin SDIP footprint but different pinout (VO/VCC swapped) | Choose only if system supply exceeds 13 V and layout allows pinout rework - not drop-in replaceable |
Compared with PS9307AL2-AX, TLP3547 offers lower cost but requires external UVLO and tighter layout controls, while IX3407S matches output capability and creepage but imposes higher supply voltage and non-compatible pinout - making PS9307AL2-AX the optimal choice for 10–30 V systems needing certified, integrated, and layout-efficient gate drive.

FAQ
What is the maximum recommended forward current for the PS9307AL2-AX LED input?
The PS9307AL2-AX specifies a recommended forward current of 8–12 mA (IF(ON)) for reliable operation. Absolute maximum rating is 25 mA continuous, but exceeding 12 mA provides no performance benefit and accelerates LED aging. Pulse operation up to 1.0 A is allowed only for <1 µs width at ≤0.5% duty cycle - not intended for normal switching.
Does the PS9307AL2-AX support both high-side and low-side IGBT configurations?
Yes - the PS9307AL2-AX is a high-side gate driver (VO is source output). It directly drives the gate of high-side IGBTs referenced to the switching node. For low-side configuration, VO connects to the IGBT gate and GND serves as emitter reference. It does not support floating-bus or bootstrap configurations natively - external circuitry is required for those topologies.
Can Pin 2 (NC) on the PS9307AL2-AX be used as a shield or ground connection?
No - Pin 2 is explicitly designated as "No Connection" (NC) in the datasheet. It may be left floating or tied to GND on the input side only. Using it as a shield, signal return, or output-side ground violates the internal isolation barrier and degrades CMR performance. The internal shield structure is fixed and not accessible via Pin 2.
What is the significance of the "-AX" suffix in PS9307AL2-AX?
The "-AX" suffix denotes the standard packaging variant: tape-and-reel with 20 pcs per cut tape unit, Pb-free Ni/Pd/Au plating, and compliance with UL/CSA/SEMKO safety approvals. It is distinct from "-E3" (2,000 pcs/reel embossed tape) and "-V" (VDE-certified version). All -AX units are fully specified per R08DS0122EJ0101 Rev.1.01.
How does the PS9307AL2-AX handle supply voltage ramp-up during system startup?
The PS9307AL2-AX incorporates UVLO with 0.4 V hysteresis to prevent erratic output behavior during VCC ramp-up. Output remains disabled until VCC exceeds 8.6 V (rising threshold); it stays active down to 6.8 V (falling threshold). To avoid false triggering, the datasheet mandates that VCC slew rate be limited to ≤3 V/µs - achieved via RC filtering or soft-start circuitry on the 10–30 V supply rail.
