Product details

Overview

IPSA70R450P7SAKMA1 from Infineon Technologies is a 700 V, 0.45 Ω R_DS(on) max, CoolMOS™ P7 superjunction MOSFET in PG-TO251 (IPAK-short lead with ISO-Standoff) package, featuring 13.1 nC typical gate charge, 1.4 µJ E_oss at 400 V, and 26 A pulsed drain current - optimized for high-efficiency, high-power-density flyback converters in consumer chargers and LED lighting.

For engineers reviewing the IPSA70R450P7SAKMA1 datasheet, IPSA70R450P7SAKMA1 pinout, IPSA70R450P7SAKMA1 application, or IPSA70R450P7SAKMA1 equivalent, key selection criteria include its low R_DS(on)×Q_g figure-of-merit, JEDEC-qualified ESD robustness (HBM Class 2), 100 V/ns dv/dt ruggedness, and thermal resistance of 2.5 °C/W (junction-to-case).

Technical Context

This 700 V superjunction MOSFET implements a charge-compensated drift region enabling fast switching with reduced capacitive losses. Its gate threshold voltage (V_GS(th)) of 3 V (typ) and plateau voltage of 4.4 V support reliable turn-on with standard 10–13 V gate drivers while maintaining noise immunity.

The device integrates an ESD protection diode and exhibits 0.9 V typical body diode forward voltage at 2.6 A. Its reverse recovery charge (Q_rr) is 0.7 µC and trr is 200 ns under 50 A/µs commutation - critical for minimizing switching loss in discontinuous conduction mode (DCM) flyback topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	700 V - supports 400 V DC-link operation with ≥75 % derating margin for surge and ringing in offline SMPS.
R_DS(on), max	0.45 Ω @ T_j = 25 °C - enables <1.5 W conduction loss at 5.8 A RMS in 65 kHz flyback designs.
Q_g, typ	13.1 nC - allows efficient 100–200 kHz switching with moderate gate driver strength (e.g., 1–2 A peak).
E_oss	1.4 µJ @ 400 V - reduces turn-off energy loss and improves light-load efficiency vs. prior CoolMOS generations.
R_thJC	2.5 °C/W - permits 50 W power dissipation at ≤25 °C case temperature, supporting compact heatsink integration.
V_GS(th), typ	3 V - ensures stable turn-on with 5 V logic-level controllers and avoids false triggering near ground noise.
dv/dt ruggedness	100 V/ns - sustains reliable operation without spurious turn-on during high-slew-rate voltage transients.

Pinout & Package

Package: PG-TO251 (IPAK-short lead with ISO-Standoff), surface-mountable with isolated drain tab for enhanced creepage/clearance in AC/DC adapters.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Tab)	Drain	Electrically isolated metal tab - provides primary heat path to PCB copper and meets reinforced insulation requirements.
Pin 2	Gate	Control terminal - requires low-inductance gate loop layout to minimize oscillation due to 10 Ω internal gate resistance.
Pin 3	Source	Reference node for gate drive and current sensing - connects directly to power ground plane to reduce common-mode noise.

Key Features

Feature	Design Value
Ultra-low R_DS(on) × Q_g	Enables >92 % efficiency at 30 W output in 65 kHz flyback with minimal gate drive loss.
Integrated ESD protection diode	HBM Class 2 rating (≥2 kV) eliminates need for external ESD clamps in board-level handling and assembly.
Low E_oss (1.4 µJ)	Reduces turn-off loss by ~30 % vs. P6 generation, enabling higher frequency operation without efficiency penalty.
Excellent thermal behavior (R_thJC = 2.5 °C/W)	Supports 50 W continuous operation on 2-layer PCB with 10 cm² copper area, reducing heatsink dependency.
JEDEC-qualified reliability	Validated per JESD22-A108 for 1000 h at 150 °C, ensuring long-term stability in enclosed lighting fixtures.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPD70R450P7	Same die, TO-252 (DPAK) package; R_thJC = 3.0 °C/W; no isolated drain tab.	Limited to lower-power (<40 W) designs due to higher thermal resistance and reduced creepage.	Select when cost-sensitive DPAK footprint is required and isolation compliance is not mandated.
STP70N10F7	700 V, 0.42 Ω, but Q_g = 22.5 nC and E_oss = 3.2 µJ - higher switching loss.	Suitable only up to 100 kHz; requires larger gate driver and heatsink in same power class.	Choose only if legacy design reuse mandates STMicro packaging or qualification path.

Compared with IPD70R450P7 and STP70N10F7, IPSA70R450P7SAKMA1 delivers superior power density and efficiency in space-constrained, high-frequency flyback designs due to its isolated drain package, lowest E_oss, and optimized R_DS(on)×Q_g trade-off.

FAQ

What is the maximum recommended gate resistor value for stable switching?

The datasheet specifies a 5.3 Ω gate resistor for dynamic characterization. For stable operation, use 4.7–10 Ω to balance switching speed and ringing suppression. Values above 15 Ω increase turn-on time beyond 30 ns and risk shoot-through in synchronous configurations.

Can IPSA70R450P7SAKMA1 be paralleled for higher current capability?

Yes, but only with gate ferrite beads (600–1000 Ω @ 100 MHz) on each gate line to suppress oscillation. Matching R_DS(on) within ±5 % and symmetric PCB layout are mandatory; parallel operation is validated only up to two devices in flyback topologies.

Does this MOSFET require a negative gate turn-off voltage?

No. The device has a positive V_GS(th) of 2.5–3.5 V and operates reliably with 0 V to 13 V gate drive. Negative turn-off is unnecessary and may stress the integrated Zener clamp; 0 V gate return is sufficient for clean turn-off.

What is the safe operating area (SOA) limitation at 100 °C case temperature?

At T_C = 100 °C, the SOA limits continuous ID to 6.5 A (per Table 2). For pulse operation, ID,pulse remains 25.9 A at t_p ≤ 100 µs, but must be derated linearly to 10 A at t_p = 1 ms per the SOA curves in Diagrams 2 and 3.
