Product details
Overview
BYT30P-1000 from STMicroelectronics is a fast recovery rectifier diode in SOD93 plastic package, rated for 1000 V repetitive peak reverse voltage (VRRM), 30 A average forward current at Tc = 85°C, and ultra-fast 70 ns typical reverse recovery time (trr) under IF = 0.5 A / IR = 1 A conditions. It serves as a high-efficiency freewheeling diode in motor control inverters and high-frequency SMPS secondary-side rectification.
For engineers reviewing the BYT30P-1000 datasheet, BYT30P-1000 pinout, BYT30P-1000 application, or BYT30P-1000 equivalent, key selection criteria include verified trr ≤ 165 ns, VRRM = 1000 V with low noise turn-off switching, and thermal resistance Rth(j–c) = 1 °C/W for conduction-cooled mounting in high-power industrial converters.
Technical Context
This diode employs optimized lifetime-controlled silicon to achieve fast, soft recovery with low reverse recovery charge (Qrr) and minimal peak reverse current (IRM), critical for reducing EMI and switching losses in hard-switched topologies. Its low VF (1.9 V @ 30 A, Tj = 25°C) and low Rth(j–c) enable high-current operation with minimal thermal derating.
The SOD93 package features case-connected cathode and is designed for direct heatsink mounting via screw torque (80 cm·N recommended). Turn-off overvoltage coefficient is specified at 4.5 with 5 µH series inductance, supporting robust snubberless design in 200 V bus applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Withstands repetitive 1 kV reverse transients in DC-link and flyback circuits without breakdown |
| trr (typ.) | 70 ns - Enables operation up to ~1 MHz switching frequency with low di/dt-induced voltage spikes |
| IF(AV) | 30 A @ Tc = 85°C - Sustains continuous 30 A conduction when case temperature held at 85°C |
| Rth(j–c) | 1 °C/W - Delivers 60 W power dissipation capability with ≤60 K junction-to-case temperature rise |
| VF @ 30 A | 1.9 V @ Tj = 25°C - Low forward drop reduces conduction loss to ~57 W at full load |
| IRM (max) | 22 A @ diF/dt = −240 A/µs - Limits reverse current overshoot during rapid commutation in IGBT-based inverters |
Pinout & Package
SOD93 plastic package with case-connected cathode; designed for conduction cooling via heatsink mounting using M4 screw (recommended torque: 80 cm·N).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead) | Forward current entry point | Connected to internal die anode; accepts up to 375 A non-repetitive surge (IFRM) |
| Cathode (Case) | Forward current exit & thermal path | Electrically and thermally tied to metal case; must be isolated from other potentials unless referenced to system ground |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast soft recovery | trr = 70 ns typ., low IRM and Qrr reduce EMI and snubber stress in high-di/dt circuits |
| High-voltage ruggedness | VRRM = VRSM = 1000 V enables use in 800 V DC-link systems with margin |
| Low thermal resistance | Rth(j–c) = 1 °C/W supports 60 W dissipation with simple heatsinking |
| Noise-optimized turn-off | Soft recovery waveform minimizes voltage ringing and audible noise in motor drives |
Applications
| Motor Drive Freewheeling | SMPS Secondary Rectification |
|---|---|
Use Scenario: Bidirectional current path in 3-phase IGBT inverter leg for induction motor control. IC Role / Device Role / Timing Role: Freewheeling diode clamping inductive kickback during IGBT turn-off. Use Value: 70 ns trr limits voltage overshoot to <250 V at diF/dt = −240 A/µs, avoiding IGBT overvoltage failure. | Use Scenario: Output rectification in 100–300 kHz resonant LLC converter delivering 500 W. IC Role / Device Role / Timing Role: High-frequency unidirectional current steering on secondary side. Use Value: Low Qrr and soft recovery cut switching losses by ≥35% vs. standard recovery diodes at 200 kHz. |

IC Role / Device Role / Timing Role: High-current AC-to-DC conversion feeding inverter DC bus. Use Value: 200 A non-repetitive surge rating handles weld initiation peaks; 30 A average rating sustains 100% duty cycle. |
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 | VRRM = 600 V, trr = 45 ns, VF = 1.75 V @ 30 A | Limited to ≤600 V DC-link; better efficiency but lower voltage margin | Select when bus voltage ≤500 V and lowest conduction loss is prioritized |
| IXYS MBR30100CT | Schottky construction, VF ≈ 1.1 V, but VRRM = 100 V only | Not suitable for >200 V applications; higher leakage at elevated Tj | Reject for 1000 V systems; consider only for low-voltage, high-efficiency SMPS |
Compared with STTH30L06D and MBR30100CT, BYT30P-1000 uniquely balances 1000 V capability with sub-100 ns recovery-enabling robust operation in 800 V industrial drives where Schottky alternatives fail and 600 V fast diodes lack margin.

FAQ
Is BYT30P-1000 still in active production?
No-BYT30P-1000 is marked "Obsolete Product(s)" in its official STMicroelectronics datasheet (Ed: 2A, October 1999). However, Aetrix Electronics maintains legacy inventory with full traceability and offers engineering support for ongoing production programs requiring this specific performance profile.
What is the maximum allowable case temperature for continuous 30 A operation?
The datasheet specifies IF(AV) = 30 A at Tc = 85°C with duty cycle δ = 0.5. For continuous (100% duty) conduction, derating is required: at Tc = 70°C, IF(AV) ≈ 25 A; at Tc = 60°C, IF(AV) ≈ 22 A-based on linear interpolation of thermal resistance and power dissipation limits.
Can BYT30P-1000 be used as a replacement for BYT30P-600?
No-while both share SOD93 packaging and similar current ratings, BYT30P-600 has VRRM = 600 V and different doping profile. Substituting into a 1000 V circuit risks catastrophic reverse breakdown; the 1000 V rating is not backward-compatible with 600 V designs due to higher leakage and thermal stress at elevated VR.
How is the cathode connection implemented in SOD93?
The cathode is electrically and thermally bonded to the metal case, which serves as the second terminal. The case must be electrically isolated from other circuit nodes unless intentionally grounded. Mounting requires insulating shoulder washers and torque-controlled fastening (80 cm·N) to ensure reliable thermal contact without mechanical fracture.
