Product details
Overview
HER153G A0G from Taiwan Semiconductor is a high-efficiency, glass-passivated single-die silicon rectifier diode rated for 1.5A average forward current, 200V repetitive peak reverse voltage (VRRM), and 50A non-repetitive surge current (IFSM). It features low forward voltage (1.0V at 1.5A, 25°C), fast reverse recovery time (50ns), and operates up to 150°C junction temperature - optimized for DC-DC converters and switching-mode power supplies.
For engineers reviewing the HER153G A0G datasheet, HER153G A0G pinout, HER153G A0G application, or HER153G A0G equivalent, key selection criteria include its DO-204AC (DO-15) package, AEC-Q101 qualification availability (via HER153GH variant), 60°C/W junction-to-ambient thermal resistance, and verified performance in freewheeling and flyback topologies under industrial ambient conditions.
Technical Context
The HER153G A0G implements a planar passivated junction structure with pure tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. Its 200V VRRM and 140V VR(RMS) rating support operation in medium-voltage AC/DC front-ends and secondary-side rectification where transient clamping and low conduction loss are critical.
Thermally, it delivers 60°C/W RθJA in standard PCB mounting, enabling reliable 1.5A continuous conduction without forced air when derated per Fig.1. The 50ns trr and 35pF junction capacitance at 1MHz/4V confirm suitability for 100–500kHz switching frequencies in isolated and non-isolated converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse blocking voltage; defines safe operating range in flyback snubber networks and output rectifiers |
| IF(AV) | 1.5 A - Continuous forward current rating at TA = 75°C; supports sustained load delivery in compact 12–24V DC-DC modules |
| VF | 1.0 V @ 1.5A, 25°C - Low conduction loss reduces heat generation and improves efficiency in high-duty-cycle applications |
| trr | 50 ns - Fast recovery minimizes switching losses and EMI in high-frequency SMPS designs |
| RθJA | 60 °C/W - Thermal resistance enables passive cooling in space-constrained industrial power supplies |
| CJ | 35 pF @ 1MHz, VR = 4V - Low junction capacitance limits displacement current and improves high-frequency noise immunity |
Pinout & Package
HER153G A0G uses the DO-204AC (DO-15) axial-leaded package with cathode indicated by a band. Leads are pure tin-plated and solderable per J-STD-002. Weight ≈ 0.400g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., transformer secondary center-tap or switch node) in half-wave/freewheeling paths |
| Cathode | Forward current exit / reverse blocking terminal | Marked with band; ties to output rail or energy storage capacitor positive; blocks 200V reverse during off-state |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enhances humidity resistance and long-term reliability in automotive-grade environments (AEC-Q101 qualified variant available) |
| Low VF (1.0V) | Reduces conduction loss by ~15% vs. standard FR15x series at 1.5A, lowering thermal stress on PCB traces |
| 50A IFSM rating | Withstands startup surges and short-circuit transients in unregulated offline supplies without degradation |
| RoHS & halogen-free | Complies with IEC 61249-2-21; suitable for consumer, industrial, and automotive end-equipment requiring green material declarations |
Applications
| DC-DC Converter Secondary Rectification | Switching Mode Inverter Output Stage |
|---|---|
Use Scenario: High-efficiency 12V–48V isolated DC-DC converter delivering 1.2A output in telecom power modules. IC Role / Device Role / Timing Role: HER153G A0G serves as synchronous rectifier replacement in secondary-side flyback topology, conducting during transformer demagnetization phase. Use Value: 1.0V VF and 50ns trr reduce conduction + switching losses by >12% versus legacy 1N540x diodes, improving full-load efficiency to ≥89%. | Use Scenario: 24V input H-bridge inverter driving 100W BLDC motor with regenerative braking. IC Role / Device Role / Timing Role: HER153G A0G functions as freewheeling diode across each MOSFET, clamping inductive kickback during PWM dead-time. Use Value: 200V VRRM and 50A IFSM ensure robust protection against 150V+ voltage spikes during rapid current reversal, preventing MOSFET avalanche failure. |
| AC-DC Adapter Output Rectifier | Industrial PLC Power Supply Input Stage |
Use Scenario: 19V/1.7A wall adapter for portable medical devices requiring low EMI and high reliability. IC Role / Device Role / Timing Role: HER153G A0G rectifies filtered 24V AC from transformer secondary in bridge configuration.

IC Role / Device Role / Timing Role: HER153G A0G provides input rectification after EMI filter, handling 1.5A continuous load with surge tolerance. Use Value: -55°C to +150°C TJ range and JESD201 Class 2 whisker resistance ensure stable operation over full industrial temperature cycle with zero field failures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06U | 1.0A IF(AV), 600V VRRM, VF = 0.95V @ 1A, trr = 35ns, SOD-123FL package | Lower current rating; surface-mount only; unsuitable for 1.5A continuous axial-leaded designs | Select when board space is constrained and peak reverse voltage exceeds 200V, but verify thermal margin at 1.5A derating |
| ON Semi MUR1520 | 1.5A IF(AV), 200V VRRM, VF = 0.93V @ 1.5A, trr = 35ns, DO-15 package, RoHS/halogen-free | Near-identical ratings; slightly faster recovery and lower VF, but no AEC-Q101 option | Prefer for cost-sensitive industrial SMPS where AEC-Q101 compliance is not required and 15ns faster trr improves light-load efficiency |
Compared with STTH1L06U and MUR1520, HER153G A0G offers optimal balance of axial-leaded manufacturability, 200V/1.5A capability, and AEC-Q101-ready qualification path - making it preferred for automotive-adjacent and high-reliability industrial power supplies where leaded assembly and long-term supply continuity matter.

FAQ
What is the maximum junction temperature rating for HER153G A0G?
The HER153G A0G has a maximum junction temperature (TJ MAX) of +150°C, validated per absolute maximum ratings in the official Taiwan Semiconductor datasheet Version I2105. This allows continuous operation in high-ambient environments such as enclosed industrial enclosures or automotive under-hood locations when properly heatsinked or PCB-coupled. Derating curves in Fig.1 must be followed above 75°C ambient.
Is HER153G A0G RoHS and halogen-free compliant?
Yes, HER153G A0G is fully RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the "Features" and "Mechanical Data" sections of the Taiwan Semiconductor datasheet. The molding compound meets UL 94V-0, and the pure tin-plated leads satisfy J-STD-002 solderability requirements - supporting compliance documentation for EU WEEE and China RoHS submissions.
What does the 'A0G' suffix mean in HER153G A0G?
The 'A0G' suffix in HER153G A0G indicates the packaging format: DO-204AC (DO-15) in 1,500-piece ammo box packaging. Per the "Ordering Information" table, 'HER15xG' denotes standard grade, 'A0G' specifies ammo box, and 'H' (e.g., HER153GH) signals AEC-Q101 qualification - HER153G A0G itself is not AEC-Q101 qualified unless ordered with the 'H' suffix.
How does HER153G A0G compare to HER152G and HER154G in voltage rating?
HER153G A0G is rated for 200V VRRM, positioned between HER152G (100V) and HER154G (300V) in the HER151G–HER158G family. All share identical IF = 1.5A, IFSM = 50A, VF = 1.0V, and trr = 50ns - differing only in reverse voltage capability. Selection depends strictly on system-level peak reverse stress; using HER153G A0G where 200V margin is sufficient avoids overdesign and cost premium of higher-voltage variants.
Can HER153G A0G be used in place of a 1N4004 or 1N5402?
HER153G A0G can replace 1N4004 (400V, 1A) or 1N5402 (100V, 3A) only with circuit validation: it matches 1N5402's 1.5A rating but exceeds its 100V VRRM (HER153G A0G = 200V); however, its 1.0V VF and 50ns trr offer superior efficiency and switching behavior. Unlike legacy 1N-series, HER153G A0G requires attention to thermal design due to higher power density - direct substitution is possible only if layout and heatsinking accommodate its higher efficiency profile.
