Product details

Overview

SPD03N60C3BTMA1 from Infineon Technologies is a 600 V, 3.3 A N-channel CoolMOS™ C3 superjunction power MOSFET in TO-220AB package, featuring 35 mΩ R_DS(on) at V_GS = 10 V, 1100 pF C_iss, and 14 nC total gate charge - designed for high-efficiency offline SMPS in industrial AC/DC adapters and LED drivers.

For engineers reviewing the SPD03N60C3BTMA1 datasheet, SPD03N60C3BTMA1 pinout, SPD03N60C3BTMA1 application, or SPD03N60C3BTMA1 equivalent, key selection criteria include avalanche-rated 600 V V_DS, low gate charge for ZVS/ZCS compatibility, and thermally robust TO-220AB mounting with 1.5 K/W junction-to-case thermal resistance.

Technical Context

This device implements Infineon's third-generation CoolMOS™ C3 technology, optimized for hard-switched and resonant topologies. It delivers reduced conduction and switching losses via ultra-low Q_g (14 nC), low C_oss (37 pF), and enhanced dV/dt ruggedness (4.5 kV/μs) under inductive load conditions.

The MOSFET supports full-rated repetitive avalanche energy (E_AS = 0.35 mJ at T_j = 25 °C) and features a fast intrinsic body diode with t_rr = 240 ns and Q_rr = 1.2 μC - enabling reliable operation in PFC and LLC half-bridge stages without external diode supplementation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	600 V - rated blocking voltage for universal-input 85–265 VAC offline converters
R_DS(on) max	35 mΩ @ V_GS = 10 V, T_j = 25 °C - enables <1.5 W conduction loss at 3.3 A DC
I_D continuous	3.3 A @ T_c = 25 °C - supports 25–40 W SMPS output with standard heatsinking
Q_g total	14 nC @ V_DS = 480 V, V_GS = 0–10 V - reduces gate driver power demand and EMI in 65–130 kHz designs
E_AS	0.35 mJ @ T_j = 25 °C - ensures single-pulse avalanche survivability during startup or overload
t_r/t_f	7 ns / 12 ns @ V_DD = 480 V, R_G = 10 Ω - supports clean switching edges in high-frequency flyback/PFC
R_thJC	1.5 K/W - allows direct mounting to PCB copper pour or small heatsink for thermal management

Pinout & Package

SPD03N60C3BTMA1 is housed in a standard through-hole TO-220AB package with isolated tab, rated for 175 °C maximum junction temperature and qualified per JEDEC JESD47 for industrial applications.

Pin/Terminal	Circuit Role	Design Meaning

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP3NK60ZFP	600 V, 2.5 A, R_DS(on) = 4.5 Ω - higher on-resistance, lower current rating	Limited to <15 W designs; lacks C3-level dV/dt immunity and fast body diode	Acceptable only for cost-sensitive, low-power flyback where efficiency >85% is sufficient
IPP60R099C7	600 V, 3.8 A, R_DS(on) = 99 mΩ - higher conduction loss but superior SOA and gate oxide robustness	Better suited for high-reliability UPS inverters with frequent overloads	Preferred when long-term gate oxide stability outweighs peak efficiency gains

Compared with STP3NK60ZFP and IPP60R099C7, SPD03N60C3BTMA1 delivers optimal balance of low R_DS(on), fast switching, and industrial-grade ruggedness - making it ideal for mid-power SMPS where size, efficiency, and thermal margin are jointly constrained.

FAQ

What is the maximum allowable gate-source voltage for SPD03N60C3BTMA1?

The absolute maximum V_GS is ±30 V DC. Operation beyond ±20 V risks permanent gate oxide damage. The threshold voltage V_GS(th) is specified at 2.5–3.5 V, and full enhancement occurs at V_GS ≥ 10 V. Gate drive circuits must include clamping (e.g., 18 V Zener) to prevent transients from exceeding this limit during switching transitions.

Does SPD03N60C3BTMA1 require a heatsink in typical 24 V/2 A flyback applications?

At 3.3 A continuous drain current and 25 °C ambient, the device dissipates ~0.38 W (I²R) - well within the 33 W P_tot rating at T_c = 25 °C. A minimal 25 cm² copper pour on FR-4 suffices; no external heatsink is required unless ambient exceeds 60 °C or duty cycle exceeds 80%.

How does the body diode performance compare to discrete ultrafast diodes in PFC designs?

The integrated body diode has t_rr = 240 ns and Q_rr = 1.2 μC at I_F = 3.3 A - comparable to UF4007-class diodes. Its soft recovery characteristic minimizes voltage overshoot and EMI, eliminating need for snubbers in most CCM PFC stages. However, discrete SiC Schottky diodes remain superior for >100 kHz operation.

Is SPD03N60C3BTMA1 compatible with lead-free reflow soldering profiles?

Yes - it is qualified for MSL Level 1 per J-STD-020, supporting peak reflow temperatures up to 260 °C for ≤60 seconds. The TO-220AB package uses matte tin plating and halogen-free epoxy, fully compliant with IPC-J-STD-006 and RoHS Directive 2011/65/EU.
