Product details
Overview
BA158GHB0G from Taiwan Semiconductor is a 1A, 600V fast recovery rectifier diode in DO-204AL (DO-41) package, featuring 150 ns reverse recovery time, 1.2 V max forward voltage at 1 A, and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in DC-DC converters and switching inverters where low conduction loss and high surge tolerance are required.
For engineers reviewing the BA158GHB0G datasheet, BA158GHB0G pinout, BA158GHB0G application, or BA158GHB0G equivalent, key selection criteria include its 600 V repetitive peak reverse voltage, 30 A non-repetitive surge rating, glass-passivated junction, RoHS/halogen-free compliance, and AEC-Q101 qualification status - all critical for automotive power supply and industrial SMPS designs.
Technical Context
This device is a single-die, unidirectional silicon rectifier optimized for high-efficiency switching power supplies. Its fast recovery (trr ≤ 150 ns) minimizes switching losses during turn-off, while the glass-passivated junction ensures stable performance under thermal cycling and humidity stress.
The BA158GHB0G operates with a maximum junction temperature of 150°C and exhibits low leakage (≤5 µA at 25°C, ≤100 µA at 125°C), enabling reliable operation in ambient temperatures up to 125°C when derated per the forward current curve. Its 60 °C/W junction-to-ambient thermal resistance supports compact board layouts without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands repetitive reverse voltage up to 600 V, suitable for 48 V–400 V DC bus applications with safety margin. |
| IF | 1 A continuous - Supports steady-state output rectification in low-to-medium power SMPS (e.g., <15 W adapters). |
| IFSM | 30 A (8.3 ms half-sine) - Handles inrush and transient surges without failure, critical for cold-start conditions. |
| trr | 150 ns - Enables efficient operation at switching frequencies up to ~200 kHz with minimal reverse recovery loss. |
| VF | ≤1.2 V @ 1 A, 25°C - Limits conduction loss to ≤1.2 W per diode, reducing thermal load in thermally constrained designs. |
| IR | ≤5 µA @ 25°C, ≤100 µA @ 125°C - Ensures low standby leakage in high-impedance feedback or hold-up circuits. |
| RθJA | 60 °C/W - Allows estimation of junction temperature rise (ΔTJ = Pd × 60) for thermal design without heatsink. |
Pinout & Package
Package: DO-204AL (DO-41), axial lead, glass-passivated chip, cathode indicated by band. Weight: 0.330 g. Leads are pure tin-plated, J-STD-002 solderable, JESD201 Class 2 whisker compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal | Connected to lower-potential side (e.g., transformer secondary center-tap or switch node); must withstand full IF and IFSM. |
| Cathode | Current exit terminal | Marked with band; connects to output capacitor/inductor; carries full forward current and blocks VRRM during off-state. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive power modules requiring zero-defect reliability under temperature cycling, vibration, and humidity stress. |
| Glass passivated junction | Prevents moisture ingress and surface contamination, improving long-term stability and preventing parametric drift in harsh environments. |
| Low VF (≤1.2 V) | Reduces power dissipation by ≥15% vs. standard recovery diodes, directly lowering heatsink requirements and improving system efficiency. |
| Fast trr (150 ns) | Minimizes reverse recovery charge (Qrr), reducing EMI generation and MOSFET/FET switching losses in synchronous or quasi-resonant topologies. |
| RoHS & halogen-free | Complies with IEC 61249-2-21; enables use in consumer, industrial, and automotive electronics subject to environmental compliance mandates. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06U | Same 1 A / 600 V rating; trr = 100 ns (faster), VF = 1.15 V (lower), but not AEC-Q101 qualified. | Suitable for industrial/commercial SMPS where automotive qualification is not mandated. | Select when faster recovery and lower VF outweigh qualification requirements. |
| ON Semi MUR106 | 1 A / 600 V; trr = 75 ns, VF = 1.1 V; JEDEC DO-41 package, RoHS-compliant, but no AEC-Q101 documentation found. | Better suited for cost-sensitive, high-volume consumer power supplies with tighter EMI budgets. | Choose for higher-speed designs needing sub-100 ns trr and lowest possible VF, accepting non-automotive qualification. |
Compared with STTH1R06U and MUR106, the BA158GHB0G trades slightly higher trr and VF for guaranteed AEC-Q101 compliance and proven reliability in automotive thermal and mechanical stress profiles - making it the preferred choice where qualification traceability and long-term field stability are mandatory.

What is the peak repetitive reverse voltage rating for BA158GHB0G?
The BA158GHB0G has a peak repetitive reverse voltage (VRRM) rating of 600 V. This value is specified in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version I2106) and defines the maximum reverse voltage the device can block repeatedly without breakdown. It is critical for selecting appropriate voltage margins in DC-DC and inverter designs.
Is BA158GHB0G qualified to AEC-Q101 standards?
Yes, BA158GHB0G is explicitly AEC-Q101 qualified, as confirmed by the "H" suffix in the ordering code and documented in the Features and Ordering Information sections of the Taiwan Semiconductor datasheet. This qualification covers stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing (uHAST), ensuring suitability for automotive under-hood applications.
What is the reverse recovery time (trr) of BA158GHB0G and how is it measured?
The BA158GHB0G has a maximum reverse recovery time (trr) of 150 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per the Electrical Specifications table. This parameter reflects the time required for the diode to transition from conduction to blocking state, directly impacting switching loss and EMI in high-frequency power converters.
What package type does BA158GHB0G use and what are its mechanical features?
BA158GHB0G uses the DO-204AL (DO-41) axial-leaded package. Key mechanical features include glass-passivated chip junction, pure tin-plated leads compliant with J-STD-002, UL 94V-0 molding compound, cathode polarity indicated by a band, and a weight of approximately 0.330 g. These attributes support automated assembly and long-term reliability in humid or thermally cycled environments.
Does BA158GHB0G have halogen-free and RoHS-compliant construction?
Yes, BA158GHB0G is both RoHS compliant and halogen-free in accordance with IEC 61249-2-21, as stated in the Features section of the Taiwan Semiconductor datasheet. This makes it suitable for environmentally regulated markets including EU, China, and Japan, and aligns with corporate sustainability requirements for consumer, industrial, and automotive electronics.
