Product details
Overview
STB30N65DM6AG from STMicroelectronics is an AEC-Q101 qualified N-channel 650 V Power MOSFET in D²PAK package, featuring 102 mΩ typ. RDS(on), 28 A continuous drain current at TC = 25 °C, and fast-recovery body diode with 126 ns trr at 25 °C. It targets high-efficiency bridge topologies and ZVS phase-shift converters in automotive and industrial power supplies.
For engineers reviewing the STB30N65DM6AG datasheet, STB30N65DM6AG pinout, STB30N65DM6AG application, or STB30N65DM6AG equivalent, key selection criteria include avalanche ruggedness (600 mJ EAS), dv/dt immunity (100 V/ns), low Qg (46 nC), Coss,eq (339 pF), and Zener-protected gate.
Technical Context
This MDmesh DM6-series MOSFET integrates a fast-recovery body diode optimized for hard-switched and resonant topologies. Its low Qrr (0.63 µC typ.) and reduced trr (126 ns) minimize switching losses during commutation, while the 100 V/ns dv/dt ruggedness ensures robust operation under high-slew-rate conditions.
The device employs a superjunction structure delivering 115 mΩ max. RDS(on) at 650 V rating, with thermal resistance RthJC of 0.56 °C/W enabling high-power density designs. Gate drive requirements are eased by low input capacitance (2000 pF) and intrinsic gate resistance (1.6 Ω).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 650 V - supports DC bus voltages up to 400 V in full-bridge ZVS converters with margin |
| RDS(on) max | 115 mΩ - enables <2.5 W conduction loss at 28 A, reducing heatsink size |
| Qg | 46 nC - lowers gate drive power and allows use of smaller gate drivers |
| trr | 126 ns @ 25 °C - minimizes reverse recovery loss in synchronous rectification and LLC phases |
| EAS | 600 mJ - withstands unclamped inductive switching events without failure |
| dv/dt ruggedness | 100 V/ns - prevents spurious turn-on in high-noise motor drive and PFC stages |
| Coss,eq | 339 pF - reduces capacitive switching loss and improves efficiency in soft-switching applications |
Pinout & Package
D²PAK (TO-263) package with exposed drain tab for thermal and electrical connection; thermally enhanced layout compatible with standard 1-inch² FR-4 PCB with 2-oz copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab (Drain) | High-side power path / heat sink interface | Electrically connected to drain; primary thermal path to heatsink; requires isolation if mounted to chassis |
| Pin 1 (Gate) | Control input | Receives 10 V logic-level drive; Zener-protected against ±25 V transients |
| Pin 2 (Source) | Reference node / return path | Serves as local ground reference for gate drive; carries full load current in low-side configuration |
| Pin 3 (Drain) | Power output terminal | Internally bonded to tab; used only when tab isolation is required; not intended for primary current path |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive powertrain and body electronics per stress test requirements |
| Fast-recovery body diode | trr = 126 ns and Qrr = 0.63 µC enable efficient freewheeling in half-bridge motor drives |
| Low RDS(on) per area | 102 mΩ typ. at 650 V improves power density vs prior MDmesh generations |

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 |
|---|---|---|---|
| IPW65R090CFD7XKSA1 | 90 mΩ RDS(on) max, 650 V, CoolMOS CFD7; higher Qg (62 nC), no AEC-Q101 rating | Preferred in non-automotive server PSUs where lower conduction loss outweighs gate drive overhead | Select when lowest RDS(on) is critical and automotive qualification is unnecessary |
| IXTH30N65X2 | 120 mΩ RDS(on) max, 650 V, HiPerFET X2; 100% avalanche rated but no fast-recovery diode spec | Suitable for snubberless flyback and hard-switched SMPS where diode recovery is managed externally | Choose when cost sensitivity dominates and integrated diode performance is secondary |
Compared with IPW65R090CFD7XKSA1 and IXTH30N65X2, STB30N65DM6AG uniquely balances AEC-Q101 compliance, fast diode recovery (126 ns), and Zener gate protection-making it optimal for automotive-grade ZVS converters where reliability under transient stress is non-negotiable.

FAQ
What is the maximum continuous drain current at 100 °C case temperature?
The STB30N65DM6AG supports 18 A continuous drain current at TC = 100 °C, as specified in Table 1 of DS13770 Rev 2. This derating reflects thermal limitations of the D²PAK package and must be applied in heatsink-limited designs operating above 25 °C ambient.
Does this MOSFET require external gate protection?
No external gate protection is required-the device integrates Zener clamping between gate and source, rated for ±25 V transient tolerance. This eliminates need for discrete TVS diodes in most automotive and industrial gate drive circuits, simplifying layout and improving reliability.
How does the body diode performance compare to standard MOSFETs?
Its body diode achieves 126 ns reverse recovery time and 0.63 µC Qrr at 25 °C-significantly faster than conventional 650 V MOSFETs (typically >250 ns trr). This enables efficient operation in hard-commutated topologies like totem-pole PFC without external SiC diodes.
Is the D²PAK package lead-free and RoHS compliant?
Yes, STB30N65DM6AG uses an ECOPACK2-compliant D²PAK package meeting RoHS Directive 2011/65/EU and REACH SVHC requirements. The device is halogen-free and qualifies for lead-free reflow soldering per JEDEC J-STD-020D.3.
