Product details
Overview
ESH3C M6G from Taiwan Semiconductor is a 3A, 150V ultra-fast surface-mount rectifier in DO-214AB (SMC) package, featuring 20 ns reverse recovery time, 0.9 V forward voltage at 3 A, and 125 A peak surge current - deployed in high-frequency switching mode power supplies for telecom and computing infrastructure.
For engineers reviewing the ESH3C M6G datasheet, ESH3C M6G pinout, ESH3C M6G application, or ESH3C M6G equivalent, key selection criteria include repetitive peak reverse voltage (150 V), junction-to-lead thermal resistance (12 °C/W), moisture sensitivity level (J-STD-020 Level 1), RoHS/halogen-free compliance, and SMC package compatibility with automated placement.
Technical Context
The ESH3C M6G employs a glass-passivated single-die silicon junction optimized for ultra-fast recovery (trr ≤ 20 ns), enabling high-efficiency operation in 100–500 kHz SMPS topologies. Its low VF (≤0.9 V @ 3 A) and low CJ (45 pF @ 4 V) reduce conduction and switching losses in freewheeling and output rectification stages.
Thermally, the device supports continuous operation up to TJ = 175°C with RθJL = 12 °C/W, allowing direct lead heat sinking in compact layouts. Polarity is unambiguously indicated by a cathode band, and matte tin-plated leads meet J-STD-002 solderability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - maximum repetitive reverse blocking voltage; defines safe operating range in DC-link and output rectifier positions |
| IF | 3 A - average forward current rating at TA = 75°C; determines continuous power handling in 12–48 V output stages |
| trr | 20 ns - ultra-fast reverse recovery time; minimizes switching loss and EMI in high-frequency converters |
| VF | 0.9 V @ 3 A, 25°C - low forward drop improves efficiency and reduces thermal load on heatsinking |
| RθJL | 12 °C/W - low junction-to-lead thermal resistance enables effective PCB copper pour heat dissipation |
| IR | 5 µA @ 25°C, 150 V - low leakage ensures stable bias in high-impedance snubber or sensing circuits |
| CJ | 45 pF @ 1 MHz, 4 V - low junction capacitance limits displacement current and ringing in fast-switching nodes |
Pinout & Package
Package: DO-214AB (SMC) - molded plastic case with matte tin-plated leads, UL 94V-0 rated, polarity marked by cathode band, weight ≈ 0.200 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal | Connected to lower-potential node (e.g., switch node in buck sync rectifier or transformer secondary center-tap) |
| Cathode | Current exit terminal | Connected to higher-potential output rail; cathode band provides unambiguous orientation for automated placement |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enhances long-term reliability under thermal cycling and humidity exposure without requiring conformal coating |
| Ultra-fast trr ≤ 20 ns | Reduces turn-off loss and diode-induced voltage spikes in 200–500 kHz LLC and phase-shifted full-bridge converters |
| J-STD-020 Level 1 moisture sensitivity | Eliminates bake requirement prior to reflow, supporting standard SMT assembly without process modification |
| RoHS & halogen-free (IEC 61249-2-21) | Meets global environmental compliance mandates for telecom and industrial end equipment without performance trade-offs |
| Low-profile SMC package | Enables <1.1 mm board height in space-constrained AC/DC adapters and server VRMs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | Same 3 A / 600 V rating but slower trr (35 ns); VF = 0.95 V @ 3 A; TO-277 package | Higher voltage margin suits 400 V bus designs; larger footprint and higher thermal resistance (RθJL = 18 °C/W) | Select when 600 V VRRM is required and layout allows TO-277 mounting |
| MBR3150 | Schottky structure; VF = 0.82 V @ 3 A but IR = 200 µA @ 125°C; same DO-214AB package | Lower conduction loss at low voltage, but unsuitable for >100 V reverse stress due to leakage and soft recovery | Select only for ≤100 V output rectification where low VF outweighs reverse leakage concerns |
Compared with STTH3L06S and MBR3150, the ESH3C M6G delivers optimal balance of 150 V blocking, 20 ns speed, and SMC package thermal performance - making it preferred for 12–48 V telecom/server SMPS where size, efficiency, and reliability are co-constrained.

FAQ
What is the maximum junction temperature rating for the ESH3C M6G?
The ESH3C M6G has a maximum junction temperature (TJ MAX) of +175°C, enabling reliable operation in high-ambient environments such as enclosed server power supplies or industrial control cabinets. This rating is validated per absolute maximum ratings table and supported by thermal derating curves showing sustained 3 A current capability up to 75°C ambient with adequate PCB copper area. The ESH3C M6G maintains specified electrical parameters within this range when mounted per recommended pad layout.
Is the ESH3C M6G RoHS and halogen-free compliant?
Yes, the ESH3C M6G is fully RoHS compliant and halogen-free per IEC 61249-2-21. This compliance is confirmed in the official Taiwan Semiconductor datasheet Version I2102 and verified through material declarations. The device uses halogen-free molding compound and matte tin-plated leads, meeting environmental requirements for telecom, computing, and industrial end equipment without compromising electrical or thermal performance.
What does the 'M6G' suffix indicate in ESH3C M6G?
The 'M6G' suffix in ESH3C M6G denotes Taiwan Semiconductor's internal manufacturing code: 'M' indicates tape-and-reel packaging (3,000 pcs/reel), '6' specifies green compound (halogen-free), and 'G' identifies the production lot/date code format per TSC marking diagram. It does not affect electrical specifications - all ESH3C devices share identical VRRM = 150 V, trr ≤ 20 ns, and VF ≤ 0.9 V characteristics regardless of suffix variant.
Can the ESH3C M6G be used as a direct replacement for ESH3B or ESH3D?
No - the ESH3C M6G is not a direct replacement for ESH3B (100 V) or ESH3D (200 V), as each variant has distinct VRRM ratings and corresponding reverse voltage capabilities. While all three share identical package, thermal specs, and forward characteristics, substituting across voltage grades risks premature failure under overvoltage stress or unnecessary derating. Always match the exact ESH3x designation to system-level reverse voltage requirements.
What is the reverse recovery time test condition for the ESH3C M6G?
The reverse recovery time (trr) of 20 ns for the ESH3C M6G is measured under standardized conditions: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, per JEDEC test methodology. This reflects real-world behavior during commutation in hard-switched topologies. The value is guaranteed maximum (not typical), ensuring design margin for EMI and loss calculations in 100–500 kHz power converters using the ESH3C M6G.
