Product details

Overview

HER153G B0G from Taiwan Semiconductor is a high-efficiency, glass-passivated silicon rectifier diode in DO-204AC (DO-15) package, rated for 1.5A average forward current, 200V repetitive peak reverse voltage (V_RRM), and 50A surge current (I_FSM). It delivers low forward voltage drop (1.0 V at 1.5 A, 25°C) and fast reverse recovery time (50 ns), making it suitable for switching-mode power supplies and freewheeling paths in automotive-grade DC-DC converters.

For engineers reviewing the HER153G B0G datasheet, HER153G B0G pinout, HER153G B0G application, or HER153G B0G equivalent, key selection criteria include its AEC-Q101-qualified variant availability, junction temperature range (–55°C to +150°C), thermal resistance (60°C/W), junction capacitance (35 pF), and compliance with RoHS and halogen-free standards per IEC 61249-2-21.

Technical Context

This device is a single-die, unidirectional, planar passivated PN-junction rectifier optimized for high-frequency switching applications. Its 50 ns reverse recovery time and low VF support reduced conduction and switching losses in SMPS topologies operating up to several hundred kHz.

The DO-204AC (DO-15) package features pure tin-plated leads compliant with J-STD-002, UL 94V-0 molding compound, and cathode band polarity marking. Thermal performance is characterized by R_θJA = 60°C/W, enabling reliable operation at full rated current with minimal heatsinking in ambient temperatures up to 75°C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - Maximum non-repetitive reverse voltage the diode blocks without breakdown; defines usable input voltage range in bridge or freewheeling configurations.
I_F	1.5 A - Continuous average forward current at T_A = 75°C; determines steady-state power handling in DC-DC output stages.
I_FSM	50 A - Peak non-repetitive surge current (8.3 ms half-sine); supports inrush and transient overload tolerance in power converters.
V_F	1.0 V @ 1.5 A, 25°C - Forward voltage drop directly impacts conduction loss (P_cond ≈ I_F × V_F) and thermal design margin.
t_rr	50 ns - Reverse recovery time measured at I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A; critical for minimizing switching loss and EMI in high-frequency SMPS.
C_J	35 pF @ 1 MHz, V_R = 4.0 V - Junction capacitance affects high-frequency impedance and snubber design in resonant or quasi-resonant topologies.
T_J max	+150°C - Maximum junction temperature; sets upper limit for thermal design and derating curves in enclosed or high-ambient environments.

Pinout & Package

HER153G B0G uses the DO-204AC (DO-15) axial-leaded package with cathode indicated by a colored band. The device has two terminals: anode and cathode - no internal connections beyond the PN junction.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to lower-potential side of load or switch node; must withstand full forward surge and continuous current.
Cathode	Forward current exit point / reverse voltage blocking terminal	Marked with band; connects to higher-potential rail; reverse-biased during off-state and must sustain full V_RRM without leakage.

Key Features

Feature	Design Value
High-efficiency rectification	VF = 1.0 V @ 1.5 A enables >92% conduction efficiency in 12 V output rails, reducing thermal stress vs. standard FR/UF diodes.
Glass-passivated junction	Enhances moisture resistance and long-term reliability under thermal cycling and humid environments, critical for automotive under-hood use.
AEC-Q101 qualification option	HER153G H variants meet stress-test requirements for automotive electronics, including temperature cycling, HTSL, and ESD robustness.
Low junction capacitance	35 pF minimizes displacement current during voltage transitions, lowering EMI generation and gate-drive loading in synchronous rectifier circuits.
Halogen-free & RoHS-compliant	Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU, supporting environmentally regulated industrial and automotive supply chains.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-efficiency rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1L06S	Same DO-204AC package, 1.0 A rating, 600 V V_RRM, 1.15 V V_F, 50 ns t_rr; lower I_F but higher V_RRM.	More suited to higher-voltage, lower-current flybacks; not recommended for 1.5 A continuous loads.	Select when system requires >400 V blocking with moderate current, and thermal headroom allows for higher V_F.
ON Semi MUR120	DO-41 package, 1.0 A I_F, 200 V V_RRM, 0.92 V V_F, 35 ns t_rr; faster recovery but lower current rating and different footprint.	Preferred in space-constrained PCBs where ultra-fast recovery dominates over current capacity.	Choose only if layout accommodates DO-41 and peak load current stays ≤1.0 A; verify mechanical fit and thermal pad compatibility.

Compared with STTH1L06S and MUR120, HER153G B0G uniquely balances 1.5 A current capability, 200 V rating, 1.0 V forward drop, and DO-204AC manufacturability-making it optimal for cost-sensitive, medium-power automotive and industrial SMPS where both current and thermal robustness are prioritized.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for HER153G B0G?

The HER153G B0G has a V_RRM rating of 200 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version I2105). This value defines the highest reverse voltage the diode can block repeatedly without avalanche breakdown. It is distinct from the HER151G (50 V) and HER154G (300 V) variants in the same family, and must be respected in circuit design to prevent premature failure.

Is HER153G B0G AEC-Q101 qualified?

HER153G B0G itself is not AEC-Q101 qualified; however, the HER153G H variant (e.g., HER153GH) is explicitly listed as AEC-Q101 qualified in the Ordering Information section. The "H" suffix denotes qualification, while "B0G" indicates standard commercial-grade packaging (tape & reel, green compound). For automotive applications requiring qualification, specify HER153GH instead of HER153G B0G.

What is the forward voltage (V_F) of HER153G B0G at rated current?

The forward voltage of HER153G B0G is 1.0 V maximum at I_F = 1.5 A and T_J = 25°C, per the Electrical Specifications table. This value is typical for the HER153G variant (HER151G–HER154G group) and reflects low conduction loss critical for efficiency in power supplies. At elevated junction temperatures (e.g., 125°C), V_F decreases slightly due to semiconductor physics, but derating curves must be consulted for design margins.

Does HER153G B0G have a specified reverse recovery time (t_rr)?

Yes, HER153G B0G has a specified reverse recovery time of 50 ns maximum, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This value applies to the HER151G–HER155G subgroup and is documented in the Electrical Specifications table. The 50 ns t_rr supports high-frequency switching up to ~500 kHz with manageable switching loss and EMI.

What package type does HER153G B0G use, and what are its key mechanical features?

HER153G B0G uses the DO-204AC (DO-15) axial-leaded package. Key mechanical features include UL 94V-0 flammability-rated epoxy molding, pure tin-plated leads compliant with J-STD-002 solderability, cathode polarity marked by a visible band, and a nominal weight of 0.400 g. The package outline dimensions and marking diagram are provided in the official Taiwan Semiconductor datasheet (Version I2105, Page 5).
