Product details
Overview
PS9552L1-AX from NEC Electronics is an IGBT gate drive photocopler with 2.5 A peak output current, ±15 kV/μs common mode transient immunity (CMR), and 0.5 μs maximum propagation delay. It features UVLO protection with hysteresis and is housed in an 8-pin DIP package with long creepage distance for enhanced isolation in high-voltage motor drives and industrial inverters.
For engineers reviewing the PS9552L1-AX datasheet, PS9552L1-AX pinout, PS9552L1-AX application, or PS9552L1-AX equivalent, key selection criteria include peak output current capability, CMR performance under fast transients, UVLO threshold stability across temperature, and creepage distance compliance for safety-critical gate drive isolation.
Technical Context
The PS9552L1-AX integrates a GaAlAs LED input stage with a monolithic photo-diode, signal processing circuit, and power output transistor on a single chip. Its output stage delivers high-current switching (2.5 A peak) with fast tPLH/tPHL ≤ 0.5 μs and built-in UVLO that activates at VUVLO+ = 11.0–13.5 V with 1.6 V hysteresis.
Designed specifically for IGBT/MOSFET gate driving, it supports supply voltages from 15 V to 30 V (VCC–VEE), operates from −40°C to +100°C, and achieves 5,000 Vr.m.s. isolation voltage per UL/CSA/BSI standards. The lead-bending DIP package provides ≥8 mm outer creepage distance for reinforced insulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Output Current | 2.5 A MAX - sufficient to directly drive 75 A/1200 V IGBTs without external buffer stages |
| Propagation Delay | tPLH/tPHL ≤ 0.5 μs - enables >500 kHz switching in high-frequency inverter designs |
| CMR (High/Low Level) | ±15 kV/μs MIN - suppresses false triggering during fast dV/dt events on IGBT collectors |
| UVLO Threshold | VUVLO+ = 11.0–13.5 V, hysteresis = 1.6 V - prevents gate drive under insufficient supply while avoiding oscillation near trip point |
| Isolation Voltage | 5,000 Vr.m.s. - certified for reinforced insulation per UL, CSA, BSI, SEMKO, NEMKO, DEMKO, FIMKO |
| Creepage Distance | ≥8 mm - meets IEC 60664-1 requirements for Pollution Degree 2 in industrial environments |
| Operating Temperature | −40°C to +100°C - supports deployment in enclosed motor control cabinets without forced cooling |
Pinout & Package
PS9552L1-AX uses an 8-pin plastic DIP package with lead bending for long creepage distance (≥8 mm). Dimensions: 9.25 mm × 6.5 mm × 3.5 mm (L×W×H), 2.54 mm pitch, 0°–15° lead bend angle.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4 | NC (No Connect) | Internally unconnected; must remain floating - no routing or grounding allowed |
| 2 | Anode | LED anode input - requires series resistor to limit IF to 7–16 mA per recommended operating conditions |
| 3 | Cathode | LED cathode - referenced to input ground; reverse voltage rating is only 5 V |
| 5 | VEE | Output emitter reference - tied to IGBT emitter or MOSFET source; defines low-side return path |
| 6, 7 | VO | Parallel-connected output terminals - deliver combined 2.5 A peak to IGBT gate; must be routed with equal impedance |
| 8 | VCC | Positive output supply - powers internal driver stage; requires local 0.1 μF bypass capacitor within 10 mm |
Key Features
| Feature | Design Value |
|---|---|
| UVLO with Hysteresis | Prevents partial turn-on of IGBT during brown-out by holding output off until VCC rises above 13.5 V and releasing only below 10.7 V |
| High CMR at Both Logic Levels | ±15 kV/μs immunity at VO high and VO low ensures robust operation during simultaneous high dV/dt on collector and emitter |
| Monolithic Power Output Stage | Eliminates discrete transistor buffers - reduces component count, layout area, and parasitic inductance in gate loop |
| Pb-Free Construction | Ni/Pd/Au plating meets RoHS Directive 2011/65/EU and JEDEC J-STD-020 reflow profile (260°C peak) |
| Long Creepage DIP Package | 8 mm minimum outer creepage satisfies reinforced insulation requirements for 1000 VDC working voltage systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar IGBT gate drive photocopler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Toshiba TLP350 | Lower peak output current (1.5 A), slower tPLH/tPHL (0.6 μs MAX), same 8-pin DIP package | Suitable for ≤30 A IGBTs; lacks UVLO hysteresis - requires external supervision circuitry | Select when cost sensitivity outweighs need for 2.5 A drive or UVLO precision |
| IXYS IX3130 | Higher CMR (25 kV/μs), integrated Miller clamp, but requires external gate resistor and bootstrap supply | Targeted at high-reliability industrial drives where active Miller clamping is mandatory | Select when system-level fault protection (e.g., desaturation detection) is required beyond basic isolation |
Compared with TLP350 and IX3130, PS9552L1-AX delivers superior peak current and integrated UVLO hysteresis in a drop-in DIP package, making it optimal for cost-sensitive yet performance-demanding IGBT drivers where board space and component count are constrained.

FAQ
What is the maximum peak output current specification for PS9552L1-AX?
The PS9552L1-AX has a maximum peak output current of 2.5 A, tested at ≤10 μs pulse width and 0.2% duty cycle. This rating allows direct drive of medium-power IGBTs (e.g., 75 A/1200 V) without external buffer transistors. The device maintains ≥2.0 A minimum output current under the same conditions, ensuring consistent gate charging performance across process and temperature variations.
Does PS9552L1-AX include under-voltage lockout (UVLO) protection?
Yes, PS9552L1-AX includes integrated UVLO with hysteresis. The turn-on threshold (VUVLO+) ranges from 11.0 V to 13.5 V, and the turn-off threshold (VUVLO−) ranges from 9.5 V to 12.0 V, yielding a guaranteed 1.6 V hysteresis. This prevents erratic gate drive during supply brownouts and eliminates need for external UVLO circuitry in PS9552L1-AX-based designs.
What safety certifications does PS9552L1-AX hold?
PS9552L1-AX is UL approved (File No. E72422), CSA approved (No. CA 101391), BSI approved (Nos. 8937, 8938), SEMKO approved (No. 615433), NEMKO approved (No. P06207243), DEMKO approved (No. 314091), and FIMKO approved (No. FI 22827). Optional DIN EN60747-5-2 (VDE0884 Part 2) approval is available under suffix -V.
What is the creepage distance of PS9552L1-AX and why is it important?
The PS9552L1-AX provides ≥8 mm minimum outer creepage distance due to its lead-bending DIP construction. This exceeds IEC 60664-1 requirements for reinforced insulation at 1000 VDC, enabling use in industrial equipment with high working voltages and pollution degree 2 environments without additional spacing or potting - critical for achieving UL/CSA certification in motor drives.
How does PS9552L1-AX achieve high common-mode transient immunity (CMR)?
PS9552L1-AX achieves ±15 kV/μs minimum CMR through monolithic integration of the photodiode, signal processor, and output transistor on one die, combined with internal shielding and optimized layout. The test condition specifies VCM = 1.5 kV applied between input (pins 1–4 shorted) and output (pins 5–8 shorted), confirming immunity to fast transients typical of IGBT switching in noisy industrial settings.
