Product details

Overview

STPSC1006D from STMicroelectronics is a 600 V, 10 A average forward current silicon carbide Schottky diode in TO-220AC package, featuring negligible reverse recovery charge (12 nC), temperature-independent switching, and 175 °C maximum junction temperature. It serves as a high-efficiency PFC boost diode in hard-switching AC-DC front-ends for industrial SMPS and server power supplies.

For engineers reviewing the STPSC1006D datasheet, STPSC1006D pinout, STPSC1006D application, or STPSC1006D equivalent, key selection criteria include its zero-recovery behavior, low Qc at 150 °C, thermal resistance of 2 °C/W, and suitability for high-frequency, high-temperature PFC stages where Si diodes exhibit excessive losses.

Technical Context

This SiC Schottky diode replaces conventional silicon fast recovery diodes in critical PFC boost positions by eliminating reverse recovery current and associated switching losses. Its wide bandgap enables stable 600 V blocking with low forward voltage (1.4–1.7 V at 10 A, 25 °C) and minimal capacitive turn-off behavior across –40 to +175 °C.

The device operates with no minority carrier storage, resulting in dV/dt immunity and negligible ringing during commutation. Its 650 pF junction capacitance at 0 V and 1 MHz, combined with 12 nC total capacitive charge at 400 V/10 A, supports efficient operation up to 100 kHz+ hard-switched PFC designs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - Enables use in universal-input (90–264 VAC) PFC stages without derating.
I_F(AV)	10 A - Sustains continuous conduction mode (CCM) PFC operation at 3.3 kW output with 115 °C case temperature.
Q_c	12 nC - Reduces turn-off loss by >90% vs. comparable Si FRD, enabling higher frequency and smaller EMI filters.
R_th(j-c)	2 °C/W - Allows direct heatsink mounting with predictable thermal margin up to 175 °C junction temperature.
V_F @ 10 A, 25 °C	1.4–1.7 V - Delivers lower conduction loss than SiC diodes with higher VF, improving full-load efficiency.
C_j @ 0 V	650 pF - Limits displacement current during high-dV/dt transitions, reducing gate drive stress on MOSFETs.
T_j(max)	175 °C - Supports compact thermal design in enclosed industrial power supplies without forced air.

Pinout & Package

TO-220AC package: single-diode configuration with anode and cathode leads mounted on isolated tab; case is electrically connected to cathode; recommended mounting torque 0.4–0.6 N·m; UL94 V0 epoxy; lead-free second-level interconnect per JEDEC JESD97.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Lead 1)	Input terminal for forward current flow	Connected to PFC inductor node; carries full boost current with minimal voltage drop.
Cathode (Lead 2)	Output terminal / common reference	Electrically tied to TO-220AC metal tab; must be isolated from heatsink unless referenced to system ground.
Tab (Case)	Cathode connection / thermal path	Provides primary thermal conduction path to heatsink; electrically identical to Lead 2.

Key Features

Feature	Design Value
No reverse recovery	Eliminates recovery current tail and associated switching loss, enabling clean hard-switched PFC waveforms.
Temperature-stable Q_c	12 nC remains constant from 25 to 150 °C, ensuring consistent turn-off loss across operating range.
Low R_th(j-c)	2 °C/W allows 10 A continuous conduction at T_C = 115 °C without exceeding 175 °C junction limit.
High V_RRM/I_F ratio	600 V rating at 10 A enables single-device solution for 3.3 kW telecom rectifiers without series stacking.

Equivalent & Alternatives

The following parts are listed as comparable options for similar SiC Schottky diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
C3D10060A	Same 600 V/10 A rating; 1.55 V VF @ 10 A, 25 °C; 13 nC Qc; TO-220-2L package with isolated tab.	Higher VF increases conduction loss by ~0.15 W at 10 A; identical thermal performance.	Select if sourcing flexibility required; verify tab isolation compatibility with heatsink mounting.
SS10P6	Silicon Schottky; 60 V max VRRM; 10 A IF(AV); VF ≈ 0.7 V; significant IR at >125 °C; not suitable above 120 °C.	Cannot replace in 600 V PFC; limited to low-voltage DC-DC outputs or OR-ing circuits.	Only viable for non-PFC, low-voltage (<100 V) applications where SiC cost premium is unjustified.

Compared with C3D10060A, STPSC1006D offers lower VF and tighter Qc spec, improving efficiency in high-duty-cycle PFC; versus SS10P6, it enables 600 V operation with stable high-temperature leakage, making it the only viable option for universal-input front-ends.

FAQ

Is STPSC1006D still in active production?

No - STPSC1006D is marked "Obsolete Product(s)" in the official ST datasheet (Rev 1, May 2008). However, Aetrix Electronics maintains legacy inventory with full traceability and supports design-in continuity through controlled distribution and cross-reference guidance for functionally aligned replacements.

Can STPSC1006D be used in place of a silicon fast recovery diode in existing PFC designs?

Yes - STPSC1006D is a direct functional replacement for 600 V Si FRDs in PFC boost stages. Its zero-recovery behavior eliminates snubber networks, reduces MOSFET voltage overshoot, and lowers EMI filter requirements. Layout changes may be needed to accommodate its lower thermal resistance and cathode-tab connection.

What is the maximum allowable case temperature for continuous 10 A operation?

The datasheet specifies I_F = 10 A at T_C = 115 °C. With R_th(j-c) = 2 °C/W and T_j(max) = 175 °C, the maximum sustainable case temperature is 115 °C. Exceeding this requires derating - e.g., 8.5 A at 125 °C case - to maintain junction safety margin.

Does STPSC1006D require a gate driver or external control circuitry?

No - STPSC1006D is a two-terminal passive diode with no control inputs. It operates autonomously based on anode-cathode voltage polarity and current direction. No gate driver, bias supply, or timing circuitry is needed, simplifying PFC stage implementation versus active switches.
