Product details

Overview

BYT230PIV-400 from STMicroelectronics is a dual fast recovery rectifier diode in ISOTOP package, rated for 400 V repetitive peak reverse voltage, 30 A average forward current (Tc = 75°C), and 50 ns maximum reverse recovery time (trr). It serves as a free-wheeling diode in high-frequency switch-mode power supplies and motor control circuits, delivering low switching losses and low-noise turn-off.

For engineers reviewing the BYT230PIV-400 datasheet, BYT230PIV-400 pinout, BYT230PIV-400 application, or BYT230PIV-400 equivalent, key selection criteria include trr ≤ 50 ns at 100°C, V_F ≤ 1.4 V at 30 A/100°C, 2500 V_RMS insulation rating, and ISOTOP thermal coupling performance with R_th(j-c) = 0.8 °C/W per diode.

Technical Context

This dual-diode device integrates two independent fast recovery rectifiers in a single insulated metal-base package. Each diode exhibits soft reverse recovery behavior with I_RM ≤ 12 A and Q_rr dependent on dI_F/dt - e.g., 50 nC at 200 A/µs (T_j = 100°C).

The ISOTOP package provides galvanic isolation (2500 V_RMS) and low parasitic inductance (< 5 nH) and capacitance (45 pF), enabling stable operation in hard-switched topologies where voltage overshoot and EMI must be minimized during turn-off.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - supports DC bus voltages up to 280 V RMS in SMPS designs with safety margin
trr (max)	50 ns - enables operation at ≥100 kHz switching frequencies with minimal recovery loss
I_F(AV)	30 A @ T_c = 75°C - defines continuous conduction capability with heatsink mounting
V_F (max)	1.4 V @ 30 A, 100°C - determines conduction loss P_cond ≈ 1.1×I_F(AV) + 0.0095×I_F(RMS)²
R_th(j-c)	0.8 °C/W per diode - sets junction-to-heatsink thermal resistance for thermal design
Insulation	2500 V_RMS - allows direct mounting on live heatsinks without additional isolation
C_j	45 pF - limits capacitive coupling noise in high-dV/dt environments

Pinout & Package

BYT230PIV-400 uses the ISOTOP (Insulated Super Top) thermally enhanced plastic package with four terminals: two anodes (A1, A2) and two cathodes (K1, K2), arranged symmetrically for dual-diode configuration. Mounting requires six M4 screws (torque ≤1.5 N·m) to ensure low thermal resistance and reliable insulation.

Pin/Terminal	Circuit Role	Design Meaning
A1	Anode of Diode 1	Connects to inductive load or switching node requiring freewheeling path
K1	Cathode of Diode 1	Common return path for Diode 1; electrically isolated from heatsink
A2	Anode of Diode 2	Independent freewheeling path - usable for phase-leg or dual-output configurations
K2	Cathode of Diode 2	Isolated return for Diode 2; enables split-rail or interleaved converter layouts

Key Features

Feature	Design Value
Fast recovery time	trr ≤ 50 ns ensures minimal tail current and reduced EMI in hard-switched converters
Low forward voltage	V_F ≤ 1.4 V @ 30 A/100°C lowers conduction loss and thermal stress under full load
Galvanic isolation	2500 V_RMS insulation enables direct heatsink mounting without insulating pads or washers
Low parasitic inductance	< 5 nH minimizes voltage overshoot during diode turn-off in high-dI/dt circuits
Thermal coupling	R_th(c) = 0.1 °C/W between diodes enables balanced thermal sharing in dual-channel use

Applications

Motor Drive Inverter

Use Scenario: Output rectification in 1–3 kW telecom or server PSUs with active clamp forward topology.

IC Role / Device Role / Timing Role: High-current, low-loss output stage rectifier handling 30 A DC with minimal thermal derating.

Use Value: 0.8 °C/W R_th(j-c) per diode allows compact heatsink design while maintaining T_j ≤ 125°C at full load.

UPS Power Stage

Welding Inverter

Use Scenario: Bidirectional energy transfer in online UPS inverters with regenerative braking capability.

IC Role / Device Role / Timing Role: Reverse-biased blocking element during battery charging; forward-conducting during inverter mode.

IC Role / Device Role / Timing Role: High-repetition surge handling (10 ms pulses) during arc ignition and re-strike cycles.

Use Value: 350 A non-repetitive surge rating sustains 200 A peak currents for >5000 cycles without degradation.

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	Single-diode TO-247; 600 V V_RRM, 30 A I_F(AV), trr = 65 ns	Lacks dual-diode integration and ISOTOP insulation; requires external isolation	Choose when higher voltage rating is needed and board space permits discrete mounting
IXYS MBR4045PT	Dual-diode TO-247AC; 45 V V_RRM, 40 A I_F(AV), trr = 45 ns	Lower voltage rating unsuitable for 400 V bus; higher current but no insulation	Use only in low-voltage, high-current DC-DC outputs where isolation is handled elsewhere

Compared with STTH30L06D and MBR4045PT, BYT230PIV-400 uniquely combines dual-diode integration, 400 V rating, 50 ns trr, and 2500 V_RMS insulation in one package - eliminating isolation components and reducing PCB footprint by ~40% in SMPS and motor drive designs.

FAQ

What is the maximum junction temperature and how does it affect derating?

The maximum operating junction temperature is 150°C. Derating follows Fig. 3 in the datasheet: at 75°C case temperature, I_F(AV) = 30 A (δ = 0.5); above 75°C, linear derating applies down to zero at 150°C. Thermal design must maintain T_j ≤ 150°C using R_th(j-c) = 0.8 °C/W and heatsink R_th(c-a).

Can BYT230PIV-400 be used in parallel with another unit for higher current?

No - parallel operation is not recommended. The device lacks built-in current-sharing features, and mismatched V_F and thermal coupling between units can cause uneven current distribution. For higher current, use a single higher-rated diode or redesign with interleaved phases.

What is the significance of the ISOTOP package's 2500 V_RMS insulation rating?

The 2500 V_RMS rating certifies galvanic isolation between the die and the metal baseplate, allowing direct mechanical mounting to a live heatsink without insulating hardware. This simplifies thermal design and eliminates creepage/clearance risks in Class I AC-connected equipment.

How does the 50 ns trr specification relate to actual circuit performance?

The 50 ns trr is measured under standardized conditions (T_j = 100°C, I_F = 1 A, V_R = 30 V, dI_F/dt = −15 A/µs). In real circuits, trr increases with higher I_F and dI_F/dt - e.g., t_IRM reaches 75 ns at 30 A/−120 A/µs - so layout inductance and snubber design must account for this scaling.
