Renesas PS9307AL-V-E3-AX

Overview

PS9307AL-V-E3-AX from Renesas Electronics is a 6-pin SDIP photovoltaic gate driver IC with AlGaAs LED input and integrated power MOSFET output stage, delivering 0.6 A peak output current, ±50 kV/µs common-mode transient immunity, and 150 ns max propagation delay. It is designed for isolated IGBT and power MOSFET gate driving in industrial inverters and AC servo systems.

For engineers reviewing the PS9307AL-V-E3-AX datasheet, PS9307AL-V-E3-AX pinout, PS9307AL-V-E3-AX application, or PS9307AL-V-E3-AX equivalent, this device offers verified high-speed isolation, reinforced insulation (UL1577, CSA C22.2 No.62368-1, VDE EN 60747-5-5), and surface-mount gull-wing lead form optimized for compact motor drive PCB layouts.

Technical Context

The PS9307AL-V-E3-AX integrates an optically coupled AlGaAs LED input stage with a monolithic photo-diode, signal processing circuit, and dual power MOSFET output stage on a single die. Its architecture enables direct gate drive of IGBTs without external level-shifting or buffer stages.

It features under-voltage lockout (UVLO) with 8.6–9.8 V turn-on threshold and 0.4 V hysteresis, plus high-speed switching (tPLH/tPHL ≤ 150 ns) and robust noise immunity via shielded internal construction and 7 mm minimum creepage distance.

FAQ

What is the maximum recommended forward current for the PS9307AL-V-E3-AX LED input?

The PS9307AL-V-E3-AX has a recommended forward current of 8–12 mA (IF(ON)) per datasheet R08DS0122EJ0101. Absolute maximum continuous forward current is 25 mA, but sustained operation above 12 mA accelerates LED degradation and reduces isolation lifetime. For reliable 10-year operation in industrial environments, maintain IF at 10 mA with 1.56 V typical VF at 25 °C.

Does the PS9307AL-V-E3-AX require an external bypass capacitor on the VCC pin?

Yes, the PS9307AL-V-E3-AX requires a ≥1.0 µF ceramic bypass capacitor between VCC and GND, placed within 10 mm of the device pins. This stabilizes the output-stage supply during high di/dt gate switching events and prevents UVLO false triggering. The capacitor must be rated for ≥35 V and located adjacent to Pin 6 (VCC) and Pin 4 (GND) per usage caution section on page 16 of the datasheet.

What safety certifications apply to the PS9307AL-V-E3-AX?

The PS9307AL-V-E3-AX carries UL1577 (double protection), CSA CAN/CSA-C22.2 No.62368-1 (reinforced insulation), SEMKO EN 62368-1/IEC 62368-1, and optional VDE DIN EN 60747-5-5 approval. These certifications validate its 5000 V_r.m.s. isolation rating, 7 mm creepage, and suitability for use in Class I and Class II equipment per IEC 61800-5-1.

Can Pin 2 (NC) on the PS9307AL-V-E3-AX be grounded or left floating?

Pin 2 (NC) on the PS9307AL-V-E3-AX may be either left floating or connected directly to GND on the input side (VEE). It must never be connected to signal traces, used as a bypass path, or tied to output-side potentials. Per page 16 of the datasheet, improper use of Pin 2 degrades internal noise immunity and may cause erratic output behavior during high dv/dt events.

What is the purpose of the shield terminal shown in the top-view pin diagram of the PS9307AL-V-E3-AX?

The shield terminal in the PS9307AL-V-E3-AX is an internal conductive layer between the LED and output die, electrically connected to Pin 4 (GND). It minimizes capacitive coupling across the isolation barrier, directly enabling the ±50 kV/µs common-mode transient immunity (CMR) specification. External PCB layout must maintain clearance between shield and high-dv/dt traces to preserve this performance.
