Product details
Overview
BYT261PIV-1000 from STMicroelectronics is a dual fast recovery rectifier diode in ISOTOP package, rated for 1000 V repetitive peak reverse voltage, 60 A average forward current (Tc = 50°C), and 70 ns maximum reverse recovery time (trr) at Tj = 100°C. It delivers low switching losses and low noise turn-off in high-frequency power converters.
For engineers reviewing the BYT261PIV-1000 datasheet, BYT261PIV-1000 pinout, BYT261PIV-1000 application, or BYT261PIV-1000 equivalent, key selection criteria include its insulated ISOTOP thermal performance (Rth(j–c) = 0.45 °C/W per diode), 2500 VRMS insulation rating, and validated use in SMPS secondary-side rectification with dIF/dt up to –480 A/µs.
Technical Context
This dual-diode device integrates two independent fast recovery rectifiers in a single insulated plastic package. Each diode supports 1000 V VRRM, exhibits trr ≤ 70 ns under IF = 0.5 A / IR = 1 A conditions, and maintains VF ≤ 1.8 V at Tj = 100°C and IF = 60 A.
The ISOTOP package provides galvanic isolation (2500 VRMS), low parasitic capacitance (45 pF), and minimal inductance (< 5 nH), enabling stable operation in hard-switched topologies where reverse recovery behavior directly impacts EMI and efficiency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Withstands 1 kV repetitive reverse voltage without breakdown; suitable for 800 V DC bus designs with margin. |
| IF(AV) | 60 A @ Tc = 50°C - Sustains continuous conduction in high-power SMPS outputs when heatsinked to 50°C case temperature. |
| trr (max) | 70 ns @ Tj = 100°C - Enables operation up to ~1 MHz switching frequencies with controlled reverse recovery charge (Qrr). |
| VF (max) | 1.8 V @ Tj = 100°C, IF = 60 A - Limits conduction loss to ~108 W per diode at full load (P ≈ IF × VF). |
| Rth(j–c) | 0.45 °C/W per diode - Enables junction-to-heatsink thermal path design with < 68°C rise at 60 A average current. |
| IRM (max) | 44 A @ dIF/dt = –480 A/µs - Defines peak reverse current stress during turn-off; informs snubber sizing. |
| CJ | 45 pF @ VR = 0 V, f = 1 MHz - Low junction capacitance minimizes capacitive coupling and EMI in high-dV/dt environments. |
Pinout & Package
BYT261PIV-1000 uses the ISOTOP (Insulated Standard Outline for Power) package - a molded plastic housing with four mounting screw holes (M4), integrated electrical insulation, and direct thermal conduction via baseplate. Package weight: 28 g (without screws). Recommended mounting torque: 1.3 N·m (max 1.5 N·m).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| K1 | Cathode of Diode 1 | High-side cathode connection; carries full output current in center-tapped or dual-output configurations. |
| A1 | Anode of Diode 1 | Common anode node for Diode 1; electrically isolated from Diode 2's anode (A2) in dual-diode layout. |
| K2 | Cathode of Diode 2 | Independent cathode for second diode; enables dual-output or interleaved rectification without shared cathodes. |
| A2 | Anode of Diode 2 | Isolated anode terminal; allows separate input routing for each diode, supporting asymmetrical or phase-shifted topologies. |
Key Features
| Feature | Design Value |
|---|---|
| Insulated ISOTOP package | 2500 VRMS isolation enables direct mounting on live heatsinks without additional insulation pads or bushings. |
| Low trr with controlled Qrr | 70 ns trr and predictable Qrr vs. dIF/dt (Fig. 8) allow accurate snubber loss estimation and EMI filtering. |
| Low-noise turn-off | Minimal voltage overshoot (VRP coefficient 3.3–4.5×) under Lp ≤ 2.5 µH ensures reduced RFI in compact layouts. |
| Thermal coupling management | Dedicated Rth(c) = 0.1 °C/W coupling resistance enables precise thermal crosstalk modeling when both diodes operate simultaneously. |

FAQ
What is the maximum junction temperature for BYT261PIV-1000?
The absolute maximum operating junction temperature is 150 °C, as specified in the Absolute Ratings table. Operation above this limit risks irreversible degradation of the silicon die and metallization. Derating curves in Figure 3 confirm 60 A IF(AV) is sustainable only up to Tc = 50°C - higher case temperatures require proportional current reduction to maintain Tj ≤ 150 °C.
Can BYT261PIV-1000 be used in parallel with another unit?
No - BYT261PIV-1000 is not designed for paralleling. Its ISOTOP package lacks matched VF or trr binning, and thermal coupling between units introduces uncontrolled current imbalance. For higher current, ST recommends using a single higher-rated device (e.g., BYT262PIV-1200) or redesigning with interleaved phases rather than paralleling discrete packages.
Does BYT261PIV-1000 have UL recognition for its package?
Yes - the ISOTOP package epoxy meets UL94 V-0 flammability rating, as stated in the mechanical data section on page 6. This certification validates its suitability for enclosed power equipment requiring flame-retardant materials, including ITE and industrial power supplies compliant with UL 60950-1 or UL 62368-1.
How does the ISOTOP package differ electrically from SOD93?
ISOTOP provides 2500 VRMS galvanic isolation and lower thermal resistance (0.45 °C/W vs. 0.7 °C/W for SOD93), while SOD93 offers smaller footprint and lower weight (3.79 g vs. 28 g). Electrically, ISOTOP's 45 pF capacitance and < 5 nH inductance are identical to SOD93 per diode - but ISOTOP's dual-diode layout isolates anodes (A1/A2), whereas SOD93 shares a common anode in BYT60P-1000.
