Product details
Overview
PS9332L-AX from Renesas Electronics is an 8-pin SDIP surface-mount photocoupler optimized for IGBT and power MOSFET gate driving, featuring 2.0 A peak output current, ±50 kV/μs common-mode transient immunity (CMTI), active Miller clamp, and UVLO with hysteresis - deployed in industrial inverters and induction heating systems.
For engineers reviewing the PS9332L-AX datasheet, PS9332L-AX pinout, PS9332L-AX application, or PS9332L-AX equivalent, this page delivers verified technical context, real-world switching performance (tPLH/tPHL ≤ 200 ns), isolation safety compliance (UL, CSA, VDE Option), and design-critical package dimensions for PCB layout and thermal management.
Technical Context
The PS9332L-AX integrates a GaAlAs LED input stage with a monolithic photodiode, signal processing circuit, and high-current power output transistor on a single die. Its architecture enables fast, isolated gate control with built-in protection against Miller-induced turn-on via active clamping at the CLAMP pin.
It operates across −40°C to +125°C ambient temperature with 15–30 V supply range, UVLO thresholds of 9.5–13.4 V (with 1.2 V hysteresis), and supports up to 50 kHz switching frequency. The device achieves high noise immunity through internal shielding, long creepage (8 mm), and reinforced insulation rated to 5,000 Vr.m.s..
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Output Current | 2.0 A MAX. - sufficient to drive high-Qg IGBTs (e.g., 1,000 nC) with low gate resistance and minimal rise/fall time degradation. |
| Propagation Delay | tPLH/tPHL ≤ 200 ns - ensures tight timing control in high-frequency motor drives and inverters operating up to 50 kHz. |
| CMTI | ±50 kV/μs MIN. - suppresses false triggering during fast dV/dt transients across IGBT collector-emitter nodes. |
| UVLO Threshold | VUVLO− = 9.5 V, VUVLO+ = 12.4 V - prevents gate drive under insufficient supply voltage while avoiding oscillation near threshold. |
| Isolation Voltage | 5,000 Vr.m.s. for 1 min - meets reinforced insulation requirements for industrial mains-connected equipment per UL/CSA/VDE standards. |
| Operating Temperature | −40°C to +125°C - supports deployment in under-hood automotive auxiliary inverters and sealed industrial enclosures without derating. |
| Miller Clamp Threshold | VtCLAMP = 3.0 V - triggers active sink current ≥ 0.5 A to suppress parasitic turn-on during high dV/dt commutation events. |
Pinout & Package
PS9332L-AX uses an 8-pin SDIP (Small Outline Dual In-line Package) with gull-wing leads for surface mounting. Package dimensions: 9.2 mm × 10.2 mm × 3.7 mm (L × W × H), creepage distance ≥ 8 mm, isolation distance ≥ 0.4 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (LED Input) | Connects to current-limited forward drive source; requires IF = 7–16 mA for reliable turn-on. |
| 2 | NC | No internal connection; may be tied to GND or left floating - not usable as signal path or bypass. |
| 3 | Cathode (LED Input) | Return path for LED current; reverse voltage limited to 5 V maximum. |
| 4 | NC | No internal connection; same handling as Pin 2 - no routing or grounding required beyond mechanical stability. |
| 5 | VEE (Output Ground) | Reference for low-side output stage and clamp sink path; must be star-grounded near IGBT emitter. |
| 6 | VCC (Output Supply) | Provides power to output driver stage; operates from 15–30 V with UVLO monitoring. |
| 7 | VO (Output) | High-current gate drive output (source/sink); connects directly to IGBT/MOSFET gate via low-inductance trace. |
| 8 | VCLAMP | Miller clamp control node; sinks ≥ 0.5 A when VCLAMP exceeds 3.0 V, preventing unintended turn-on. |
Key Features
| Feature | Design Value |
|---|---|
| Active Miller Clamp | Clamps gate-to-emitter voltage via dedicated VCLAMP pin at 3.0 V threshold, delivering ≥ 0.5 A sink current to suppress dv/dt-induced turn-on. |
| High CMTI | ±50 kV/μs minimum immunity ensures robust operation in noisy inverter half-bridges with >1 kV/μs collector voltage slew rates. |
| UVLO with Hysteresis | 1.2 V hysteresis between 9.5 V (falling) and 12.4 V (rising) prevents oscillatory gate drive during brown-out conditions. |
| Reinforced Isolation | 5,000 Vr.m.s. isolation rating and VDE 0884-5 option support safety-critical industrial and grid-tied applications. |
| High-Temp Operation | Rated for continuous operation at +125°C ambient, enabling placement near power stages without external heatsinking. |

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 | 1.5 A peak output, tPLH/tPHL ≤ 300 ns, CMTI = ±35 kV/μs, no integrated Miller clamp. | Lacks active clamp; requires external Zener or negative bias for Miller immunity in high-dV/dt designs. | Lower-cost option where system-level Miller suppression is already implemented externally. |
| SI8271BD-D-IS | Digital isolator-based driver, 4 A peak, tPLH/tPHL ≤ 120 ns, CMTI = ±200 kV/μs, no UVLO hysteresis. | Requires external UVLO circuitry; higher speed but less integrated protection than PS9332L-AX. | Better for ultra-fast switching (>100 kHz) with custom protection logic, but increases design complexity. |
Compared with ACPL-332J-000E and SI8271BD-D-IS, PS9332L-AX offers balanced integration - combining 2.0 A drive strength, active Miller clamp, and UVLO hysteresis in a single SDIP package - making it optimal for cost-sensitive, high-reliability industrial inverters where layout simplicity and proven field robustness are prioritized.

FAQ
What is the maximum recommended forward current for PS9332L-AX?
The absolute maximum forward current for PS9332L-AX is 25 mA, but the recommended operating condition specifies IF(ON) between 7 mA and 16 mA. Operating within this range ensures reliable LED conduction while maintaining long-term reliability and consistent CTR performance across temperature. Exceeding 16 mA continuously may accelerate LED aging and reduce isolation lifetime, especially at elevated ambient temperatures.
Does PS9332L-AX require an external pull-down resistor on the output pin?
No, PS9332L-AX does not require an external pull-down resistor on the VO pin because its output stage includes a dedicated low-side driver capable of sinking up to 2.0 A peak current. The device actively pulls the output low during turn-off, eliminating the need for external passive components - simplifying gate drive loop design and improving switching consistency in high-frequency applications.
How does the active Miller clamp function in PS9332L-AX?
The active Miller clamp in PS9332L-AX activates when the voltage at the VCLAMP pin exceeds 3.0 V, triggering an internal sink path that delivers ≥0.5 A to the IGBT gate. This clamps the gate-emitter voltage below the Miller plateau threshold, preventing parasitic turn-on during high dV/dt transitions - a critical feature for reliable operation with 1200 V IGBTs in hard-switched topologies.
What safety certifications apply to PS9332L-AX?
PS9332L-AX is UL approved (E72422), CSA approved (CA 101391), and SEMKO approved (EN 60065, EN 60950). An optional VDE 0884-5 certification is available for the PS9332L2 variant, which provides enhanced partial discharge and transient overvoltage ratings - though PS9332L-AX itself meets all core reinforced insulation requirements for industrial equipment safety standards.
Can PS9332L-AX drive both IGBTs and SiC MOSFETs?
PS9332L-AX is qualified and widely used for IGBT gate driving, and its 2.0 A peak output and fast switching (≤200 ns) make it suitable for many 650 V SiC MOSFETs with Qg ≤ 50 nC. However, for high-Qg SiC devices (>80 nC) or applications demanding <100 ns propagation delay, validation of gate loop inductance, Miller charge handling, and thermal margin under full-load conditions is required before deployment.
