Product details
Overview
ES3CBH from Taiwan Semiconductor is a 3A, 150V super fast surface-mount rectifier diode in DO-214AA (SMB) package, featuring 35 ns reverse recovery time, 0.92 V forward voltage at 1.5 A/25°C, and AEC-Q101 qualification for automotive use in snubber and freewheeling circuits.
For engineers reviewing the ES3CBH datasheet, ES3CBH pinout, ES3CBH application, or ES3CBH equivalent, key selection criteria include peak repetitive reverse voltage (150 V), surge current capability (100 A), junction-to-lead thermal resistance (24 °C/W), and moisture sensitivity level (J-STD-020 Level 1).
Technical Context
This super fast rectifier uses a glass passivated silicon junction to achieve low forward voltage and rapid charge carrier recombination, enabling high-frequency switching operation up to several hundred kHz in DC-DC converters and automotive lighting drivers.
Its single-die configuration, matte tin-plated leads, and DO-214AA package support automated placement and soldering per J-STD-002, with thermal performance validated on 10 mm × 10 mm copper PCB pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse blocking voltage; defines safe operating range in snubber and flyback clamp circuits. |
| IF | 3 A - Continuous forward current rating; supports sustained conduction in automotive power supplies. |
| trr | 35 ns - Reverse recovery time; enables efficient high-frequency rectification with minimal switching loss. |
| VF @ 1.5 A, 25°C | 0.92 V - Low forward drop reduces conduction loss and thermal stress in compact layouts. |
| RθJL | 24 °C/W - Junction-to-lead thermal resistance; allows direct heat transfer to PCB copper, critical for thermal reliability. |
| IFSM | 100 A - Non-repetitive surge current rating; withstands inrush and transient overloads in automotive systems. |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, low-profile plastic case with cathode band polarity marking and 0.110 g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of load or switch node; requires adequate copper pour for thermal dissipation. |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; ties to higher-potential rail or switching node; carries full load current during conduction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JEDEC standards. |
| Glass passivated junction | Enhances long-term stability and humidity resistance, critical for under-hood automotive environments. |
| Moisture sensitivity level 1 | Enables standard SMT assembly without baking; eliminates production delays and handling constraints. |

Applications
| DC–DC Converter | Automotive Lighting |
|---|---|
Use Scenario: High-efficiency synchronous buck converter in 12 V automotive subsystems. IC Role / Device Role / Timing Role: Freewheeling diode providing low-loss current path during high-side FET off-time. Use Value: 35 ns trr minimizes reverse recovery loss; 0.92 V VF reduces conduction loss at 3 A continuous load. | Use Scenario: LED headlamp driver with PWM dimming and thermal foldback protection. IC Role / Device Role / Timing Role: Snubber diode clamping inductive kickback from LED current regulation inductors. Use Value: 150 V VRRM safely absorbs transients up to 130 V; AEC-Q101 ensures lifetime reliability in vibration-prone environments. |
| Snubber Circuit | Freewheeling Application |
Use Scenario: RCD snubber across MOSFET drain-source in flyback power supplies. IC Role / Device Role / Timing Role: Fast recovery diode conducting snubber capacitor discharge pulse. Use Value: 100 A IFSM handles high-energy spikes; low CJ (46 pF) limits capacitive loading on switching node. | Use Scenario: Relay coil suppression and motor commutation in body control modules. IC Role / Device Role / Timing Role: Unidirectional current path releasing stored magnetic energy when drive signal turns off. Use Value: Glass passivation prevents leakage degradation under 125°C ambient; DO-214AA footprint enables high-density layout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600 V VRRM, 35 ns trr, 0.95 V VF @ 1.5 A - higher voltage rating but same speed and package. | Preferred where system-level transients exceed 150 V, e.g., 48 V mild-hybrid architectures. | Select STTH3L06S only if design requires >150 V blocking margin; otherwise ES3CBH offers better VF/trr trade-off at 150 V. |
| SB3150 | 150 V VRRM, 35 ns trr, 0.90 V VF @ 1.5 A - identical voltage/speed, slightly lower VF, same DO-214AA package. | Drop-in replacement in legacy designs; lacks AEC-Q101 qualification and halogen-free certification. | Choose SB3150 only for non-automotive industrial use where qualification and environmental compliance are not required. |
Compared with STTH3L06S and SB3150, ES3CBH uniquely combines AEC-Q101 qualification, halogen-free construction, and optimized 150 V/35 ns performance-making it the preferred choice for automotive-grade 12 V/24 V power conversion where reliability and regulatory compliance are mandatory.

FAQ
What is the maximum junction temperature rating for ES3CBH?
The ES3CBH has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows operation in under-hood automotive environments where ambient temperatures reach 125°C, provided thermal design maintains junction temperature within limit using the specified RθJL = 24°C/W and appropriate PCB copper area.
Is ES3CBH suitable for use in AEC-Q101-compliant automotive designs?
Yes, ES3CBH is explicitly qualified to AEC-Q101 Rev D for stress testing including HTGB, HTRB, TCT, and ESD. The qualification applies to the exact ES3CBH device marked "ES3CB" on the cathode band, confirming its suitability for automotive power modules, lighting controllers, and body electronics requiring certified reliability.
What is the forward voltage of ES3CBH at 3.0 A and 125°C?
Per electrical specifications, the ES3CBH exhibits a typical forward voltage of 0.84 V at IF = 3.0 A and TJ = 125°C. This value reflects reduced VF due to positive temperature coefficient of silicon diodes and is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating artifacts.
Does ES3CBH have a defined moisture sensitivity level (MSL)?
Yes, ES3CBH is rated MSL Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH and processed using standard reflow profiles without pre-baking. This simplifies SMT line integration and eliminates moisture-related popcorning risk during assembly.
What is the junction capacitance of ES3CBH and how is it measured?
The ES3CBH has a typical junction capacitance (CJ) of 46 pF, measured at 1 MHz and VR = 4.0 V with TJ = 25°C. This parameter directly impacts high-frequency switching noise and snubber effectiveness; lower CJ reduces capacitive coupling and improves EMI performance in fast-switching topologies.
