Product details

Overview

PS9307L-E3-AX from Renesas Electronics is a 6-pin SDIP photocopler optimized for IGBT and power MOSFET gate driving in high-noise industrial inverters and servo systems. It delivers 0.6 A peak output current, achieves 175 ns max propagation delay (tPLH/tPHL), and sustains ±50 kV/μs common-mode transient immunity (CMH/CML) at 125 °C ambient operation.

For engineers reviewing the PS9307L-E3-AX datasheet, PS9307L-E3-AX pinout, PS9307L-E3-AX application, or PS9307L-E3-AX equivalent, key selection criteria include its gull-wing surface-mount SDIP package, NC pin handling guidance, isolation voltage rating of 5,000 V_r.m.s., and compliance with UL, CSA, SEMKO, and optional VDE0884 Part 2 safety standards.

Technical Context

The PS9307L-E3-AX integrates a GaAlAs LED input stage with a monolithic photo-diode, signal processing circuit, and power output transistor on a single die. Its architecture enables direct drive of IGBT gates without external amplification under 30 V supply (VCC–VEE).

It operates with 8–12 mA forward current (IF), supports 10–30 V output supply range, and maintains stable switching performance across −40 to +125 °C ambient temperature. The device uses internal shielding and optimized internal layout to achieve high CMR while meeting creepage and clearance requirements for industrial isolation.

Key Specifications

Parameter	Value and Actual Design Meaning
Peak Output Current	0.6 A MAX - sufficient to directly drive medium-power IGBT gates (e.g., 1200 V/25 A) without external buffer stages
Propagation Delay	175 ns MAX (tPLH/tPHL) - enables >250 kHz switching frequency in motor control and inverter applications
Common-Mode Immunity	±50 kV/μs MIN (CMH/CML) - suppresses noise coupling in high-dv/dt environments like VFDs and servo drives
Isolation Voltage	5,000 V_r.m.s. - meets reinforced insulation requirements for industrial equipment per UL/CSA/VDE standards
Ambient Temperature	−40 to +125 °C - supports operation in enclosed enclosures and high-temperature industrial settings
Package	6-pin SDIP (Shrink Dual In-line Package), gull-wing surface mount - half footprint of 8-pin DIP, compatible with standard SMT reflow
Safety Approvals	UL E72422, CSA CA101391, SEMKO 1115598, optional VDE0884 Part 2 - certified for end-equipment safety compliance

Pinout & Package

PS9307L-E3-AX uses a 6-pin plastic SDIP (Shrink Dual In-line Package) with gull-wing leads for surface mounting. Package dimensions: 9.7 mm × 3.7 mm × 3.5 mm (L×W×H), 1.27 mm lead pitch, 0.8 mm lead thickness.

Pin/Terminal	Circuit Role	Design Meaning
1 (Anode)	LED anode input	Connects to current-limited driver (8–12 mA typical); reverse bias must stay within −2 V per spec
2 (NC)	No connection	Internally unconnected; may be tied to GND on input side or left floating - not usable as signal path or bypass
3 (Cathode)	LED cathode input	Reference return for LED drive; requires low-impedance path to complete input loop
4 (VEE)	Output emitter reference	Ground reference for output stage; must be decoupled with ≥0.1 μF capacitor placed ≤10 mm from pins 4–6
5 (VO)	Output collector	High-current open-collector output; connects to IGBT gate; VO = 0–VCC range supports active pull-down
6 (VCC)	Output supply	Positive supply for output transistor (10–30 V); requires local bypass capacitor adjacent to pin

Key Features

Feature	Design Value
High-speed switching	175 ns max tPLH/tPHL ensures precise timing control in PWM-driven IGBT gate circuits
Reinforced isolation	5,000 V_r.m.s. isolation withstand and 7 mm minimum creepage meet IEC/UL Class 1 reinforced insulation
Thermal robustness	Rated for continuous operation up to +125 °C ambient - eliminates derating concerns in compact industrial enclosures
Pb-free construction	Ni/Pd/Au plating on gull-wing leads complies with RoHS Directive 2011/65/EU and JEDEC J-STD-020
EMI-resilient layout	Integrated shield and internal separation between input/output blocks minimize capacitive coupling during fast transients

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 TLP350	0.5 A peak output, 200 ns max tPLH/tPHL, 3750 V_r.m.s. isolation, SO-6 package	Limited to lower-power IGBTs; lower CMR (25 kV/μs); lacks VDE0884 option	Choose when cost sensitivity outweighs need for 0.6 A drive or VDE certification
ON Semiconductor FOD3180	2.5 A peak output, 0.5 μs max propagation delay, 5000 V_r.m.s., SO-8 package	Higher drive strength but slower switching; larger footprint; no 125 °C rating	Prefer when driving high-C_iss IGBTs where peak current >0.6 A is required

Compared with TLP350 and FOD3180, PS9307L-E3-AX offers superior thermal rating (125 °C vs. 105 °C), faster switching than FOD3180, and higher CMR than both - making it optimal for compact, high-reliability industrial inverters operating near thermal limits.

FAQ

What is the maximum recommended forward current for PS9307L-E3-AX?

The PS9307L-E3-AX has a recommended forward current (IF) of 8–12 mA under normal operation, with an absolute maximum rating of 25 mA. Exceeding 12 mA continuously reduces LED lifetime and increases self-heating; pulsed operation up to 1.0 A is allowed only for <1 μs width and low duty cycle. Always refer to the R08DS0046EJ0001 datasheet's Recommended Operating Conditions table for PS9307L-E3-AX.

Can Pin 2 (NC) on PS9307L-E3-AX be used as a ground connection?

Pin 2 on PS9307L-E3-AX is a true no-connect (NC) terminal with no internal bond wire or circuit connection. It may be tied to the input-side GND (cathode) for mechanical stability or EMI reduction, but must never carry signal current or serve as a functional ground path. Leaving it unconnected is also acceptable per Renesas' handling notes - using it as a signal bypass degrades internal noise immunity.

Does PS9307L-E3-AX support 30 V output supply voltage?

Yes, PS9307L-E3-AX supports (VCC – VEE) up to 30 V per its Recommended Operating Conditions and Absolute Maximum Ratings. At 30 V, it delivers 0.4 A minimum high-level output current (IOH) with 10 μs pulse width and 0.5% duty cycle. Ensure proper heat dissipation: power dissipation drops to 3.9 mW/°C above 85 °C ambient.

Is PS9307L-E3-AX certified for VDE0884-2 (DIN EN60747-5-2)?

PS9307L-E3-AX is offered in a V-option variant (e.g., PS9307L-V-E3-AX) that carries DIN EN60747-5-2 (VDE0884 Part 2) approval (No. 40024069). The standard PS9307L-E3-AX is UL, CSA, and SEMKO certified but does not include VDE0884 unless explicitly ordered with the "-V" suffix. Confirm ordering code before specifying for VDE-mandated designs.

How should the bypass capacitor be placed for PS9307L-E3-AX?

A minimum 0.1 μF ceramic capacitor must be placed between VCC (Pin 6) and VEE (Pin 4) as close as possible to the PS9307L-E3-AX - with lead length ≤10 mm - to suppress high-frequency supply noise and prevent output instability. Use X7R or better dielectric; avoid shared vias or traces with other ICs. This requirement is explicitly stated in the "Notes on Handling" section of the PS9307L-E3-AX datasheet.
