Product details
Overview
BYT60P-400 from STMicroelectronics is a fast recovery rectifier diode in SOD93 package, rated for 400 V repetitive peak reverse voltage, 60 A average forward current (Tc = 80°C), and 50 ns maximum reverse recovery time (trr). It delivers low switching losses and low-noise turn-off, optimized for free-wheeling in SMPS and motor control circuits.
For engineers reviewing the BYT60P-400 datasheet, BYT60P-400 pinout, BYT60P-400 application, or BYT60P-400 equivalent, key selection criteria include its 50 ns trr at 100°C, 1.4 V max VF at 60 A/100°C, 550 A non-repetitive surge rating, and insulated SOD93 thermal performance with Rth(j-c) = 0.7 °C/W.
Technical Context
This dual-diode fast recovery rectifier operates as a single die pair in common-cathode configuration within an insulated plastic SOD93 housing. Its design targets high-frequency switching environments where low trr (≤50 ns), low Qrr, and controlled dIF/dt response (up to 480 A/µs) minimize EMI and conduction loss.
The device features 2500 VRMS insulation, 45 pF junction capacitance, and <5 nH internal inductance - enabling clean turn-off in hard-switched converters. Thermal coupling between diodes is minimized via dedicated Rth(c) = 0.1 °C/W path, supporting simultaneous conduction without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Withstands 400 V repetitive reverse voltage without breakdown in SMPS output stages. |
| IF(AV) | 60 A @ Tc = 80°C - Sustains continuous 60 A DC forward current with heatsink at 80°C ambient. |
| trr (max) | 50 ns @ Tj = 100°C - Enables operation up to ~2 MHz switching frequency with minimal reverse recovery loss. |
| VF (max) | 1.4 V @ IF = 60 A, Tj = 100°C - Limits conduction loss to ≤84 W per diode under full-load conditions. |
| Rth(j-c) | 0.7 °C/W - Delivers 85.7°C/W thermal rise per watt, enabling compact heatsink sizing for 60 A operation. |
| IFSM | 550 A @ tp = 10 ms - Handles short-duration motor startup surges or inrush currents without failure. |
| CJ | 45 pF @ VR = 0 V - Reduces capacitive coupling noise in high-dV/dt gate-drive or snubber circuits. |
Pinout & Package
SOD93 is a 3-terminal insulated plastic package with isolated metal baseplate. Terminals are arranged linearly: Cathode (K), Anode 1 (A1), Anode 2 (A2). The baseplate serves as common cathode connection and thermal interface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| K | Common cathode | Electrically and thermally connected to insulated metal baseplate; must be mounted to heatsink with 0.8 N·m torque. |
| A1 | Anode 1 | Input terminal for first diode leg; used in dual-output or interleaved converter topologies. |
| A2 | Anode 2 | Input terminal for second diode leg; enables shared cathode return in bridge or center-tap configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Fast recovery time | trr ≤ 50 ns ensures minimal reverse recovery charge (Qrr) and reduced switching loss in 100–500 kHz SMPS. |
| Insulated package | 2500 VRMS isolation eliminates need for additional insulating hardware when mounting to grounded heatsinks. |
| Low-noise turn-off | Controlled dIF/dt response and <5 nH internal inductance suppress voltage overshoot and EMI during commutation. |
| Thermal coupling management | Dedicated Rth(c) = 0.1 °C/W path prevents thermal crosstalk between diodes during simultaneous conduction. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH6004D | TO-220AC package, single diode, 400 V/60 A, trr = 65 ns, Rth(j-c) = 1.2 °C/W | Lacks dual-anode configuration and 2500 VRMS insulation; requires external insulator for heatsink mounting. | Select when space allows discrete mounting and dual-anode functionality is unnecessary. |
| IXYS MUR6040CT | TO-220AB package, dual common-cathode, 400 V/60 A, trr = 55 ns, Rth(j-c) = 1.0 °C/W | No insulation rating; baseplate is electrically active; requires isolation kit for grounded heatsinks. | Prefer when cost sensitivity outweighs insulation requirement and thermal margin permits higher Rth(j-c). |
Compared with STTH6004D and IXYS MUR6040CT, BYT60P-400 uniquely combines dual-anode topology, 2500 VRMS insulation, and 0.7 °C/W thermal resistance in SOD93 - making it optimal for compact, insulated, high-current freewheeling in space-constrained industrial converters.

FAQ
What is the maximum recommended mounting torque for BYT60P-400?
The SOD93 package specifies a recommended torque of 0.8 N·m and a maximum of 1.0 N·m for mounting screws. Exceeding 1.0 N·m risks cracking the epoxy body or deforming the leadframe, compromising thermal contact and insulation integrity. Use calibrated torque drivers during assembly.
Can BYT60P-400 replace BYT260PIV-400 in existing designs?
No - BYT260PIV-400 uses ISOTOP packaging (28 g, 10 pcs/tube), while BYT60P-400 uses SOD93 (3.79 g, 30 pcs/tube). They share electrical specs but differ in thermal resistance (0.45 °C/W vs. 0.7 °C/W), footprint, and mounting method. PCB redesign and thermal validation are required for substitution.
Does BYT60P-400 support parallel operation of both diodes?
Yes - the datasheet confirms simultaneous conduction capability with ∆Tj(diode 1) = P₁ × Rth(j-c) + P₂ × Rth(c), where Rth(c) = 0.1 °C/W accounts for thermal coupling. This enables balanced current sharing in interleaved or dual-output topologies without derating.
What is the typical junction capacitance at 100 V reverse bias?
Junction capacitance drops to approximately 12 pF at VR = 100 V, based on Figure 7 (C vs. VR curve). This low, voltage-dependent capacitance minimizes displacement current and improves EMI behavior in high-dV/dt applications such as resonant LLC converters.
