Product details
Overview
BYT231PIV-1000 from STMicroelectronics is a dual high-voltage fast recovery rectifier diode in ISOTOP package, rated for 1000 V repetitive peak reverse voltage and 30 A average forward current at Tc = 55°C with 0.5 duty cycle. It delivers 80 ns maximum reverse recovery time (trr), 1.8 V max forward voltage at 100°C, and is designed for free-wheeling in SMPS and motor control converters.
For engineers reviewing the BYT231PIV-1000 datasheet, BYT231PIV-1000 pinout, BYT231PIV-1000 application, or BYT231PIV-1000 equivalent, key selection criteria include trr ≤ 80 ns, VRRM = 1000 V, IF(AV) = 30 A per diode, ISOTOP thermal performance (Rth(j-c) = 0.8 °C/W per diode), and insulated package suitability for high-noise switching environments.
Technical Context
This dual-diode device integrates two independent fast recovery rectifiers in a single insulated ISOTOP housing, enabling compact free-wheeling paths in half-bridge or full-bridge topologies. Each diode supports 700 A repetitive peak forward current (tp = 5 µs, f = 1 kHz) and withstands 200 A non-repetitive surge current (10 ms sinusoidal).
Its low-noise turn-off behavior stems from controlled reverse recovery dynamics: tIRM ≤ 200 ns and IRM ≤ 22 A under dIF/dt = −240 A/µs, with VRP/VCC coefficient of 4.5 for overvoltage prediction in inductive switching circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Withstands 1 kV DC or peak AC reverse bias without breakdown in SMPS output stages. |
| trr (max) | 80 ns - Enables high-frequency switching (>100 kHz) with minimal commutation loss in converters. |
| IF(AV) | 30 A @ Tc = 55°C, δ = 0.5 - Sustains continuous conduction in motor drive freewheel paths with standard heatsinking. |
| VF (max) | 1.8 V @ Tj = 100°C - Limits conduction loss to ~54 W per diode at 30 A (P ≈ 1.47×IF(AV) + 0.010×IF²(RMS)). |
| Rth(j-c) | 0.8 °C/W per diode - Allows junction temperature rise of ≤40°C above case at 50 W dissipation, critical for thermal design. |
| Isolation | 2500 VRMS - Provides reinforced insulation between terminals and heatsink-mounting surface for safety-critical power systems. |
Pinout & Package
Package: ISOTOP - Insulated plastic housing with four mounting holes (M4 screws), 28 g mass, UL94 V0 epoxy, and 2500 VRMS isolation rating. Dimensions: 38.0 × 25.3 × 12.0 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input terminal for first diode; connects to switching node in half-bridge freewheel path. |
| K1 | Cathode 1 | Output terminal for first diode; ties to DC bus or load return in motor control. |
| A2 | Anode 2 | Input terminal for second diode; enables dual-channel operation or phase-leg redundancy. |
| K2 | Cathode 2 | Output terminal for second diode; electrically isolated from K1 for independent circuit routing. |
Key Features
| Feature | Design Value |
|---|---|
| Fast recovery time | trr ≤ 80 ns ensures <1% switching loss contribution at 100 kHz in hard-switched SMPS. |
| Low noise turn-off | Controlled IRM and tIRM suppress EMI generation during inductive current interruption. |
| Insulated package | 2500 VRMS isolation eliminates need for additional insulating hardware in heatsink-mounted designs. |
| Thermal coupling | Rth(c) = 0.1 °C/W between diodes enables accurate thermal modeling when both operate simultaneously. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH30L06D | 600 V VRRM, 30 A IF(AV), TO-247 package, trr = 65 ns | Limited to ≤600 V systems; lower voltage rating reduces margin in 800 V bus designs | Select only if system VRRM requirement ≤600 V and TO-247 mounting is preferred. |
| IXYS MBR40100CT | 1000 V VRRM, 40 A IF(AV), TO-247 package, Schottky-like VF but higher trr (~120 ns) | Higher conduction loss at high Tj due to VF drift; slower recovery increases switching loss | Prefer for lower VF priority in <85°C ambient; avoid where trr <100 ns is mandatory. |
Compared with STTH30L06D and MBR40100CT, BYT231PIV-1000 uniquely combines 1000 V rating, 80 ns trr, and ISOTOP insulation-enabling compact, safe, high-efficiency freewheeling in space-constrained industrial converters where voltage margin and EMI control are critical.

FAQ
What is the maximum recommended mounting torque for the ISOTOP package?
The recommended torque value for the M4 mounting screws is 1.3 N·m, with an absolute maximum of 1.5 N·m. Exceeding this risks cracking the epoxy housing or compromising thermal interface integrity. Two screws are advised for heatsink mounting; the four included screws are optimized for 0.6–2.2 mm board thickness.
Can BYT231PIV-1000 be used in parallel configurations?
Yes, but only with matched devices and symmetrical PCB layout. The 0.1 °C/W thermal coupling (Rth(c)) between diodes means unequal current sharing will cause thermal runaway unless external balancing resistors or forced-air cooling is applied. Parallel use is not recommended beyond 2 units without derating.
What is the significance of the 45 pF capacitance specification?
The 45 pF terminal-to-terminal capacitance directly impacts high-frequency EMI generation during turn-off. At 100 kHz switching, it forms a resonant tank with circuit inductance, influencing voltage ringing amplitude. Low capacitance-combined with <5 nH package inductance-ensures predictable, low-amplitude overshoot in hard-switched topologies.
How does the VRP/VCC coefficient of 4.5 affect snubber design?
The VRP/VCC = 4.5 coefficient quantifies overvoltage amplification relative to DC bus voltage during turn-off. For a 200 V bus, peak reverse voltage can reach 900 V (4.5 × 200 V), requiring snubber components rated ≥1 kV. This value is measured at dIF/dt = −30 A/µs with 5 µH series inductance and must be scaled for actual dIF/dt conditions.
