Product details
Overview
ES1JAL from Taiwan Semiconductor is a 1 A, 600 V super fast surface-mount rectifier in a Thin SMA package, featuring 35 ns reverse recovery time, 1.15 V forward voltage at 1.0 A/25°C, and 15 pF junction capacitance. It serves as a freewheeling or output rectifier in high-frequency switching power supplies.
For engineers reviewing the ES1JAL datasheet, ES1JAL pinout, ES1JAL application, or ES1JAL equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (RθJL = 28°C/W), surge current capability (60 A @ 1.0 ms), and low-profile mounting compatibility with automated SMT lines.
Technical Context
The ES1JAL employs a single-die, glass-passivated PN junction optimized for fast recovery (trr ≤ 35 ns) and low conduction loss at elevated temperatures. Its 600 V VRRM rating enables use in 400 V DC bus systems with safety margin, while RθJA = 67°C/W reflects thermal performance on a 5 mm × 5 mm copper pad.
Designed for high-frequency operation, the device delivers stable reverse leakage (< 1 µA @ 25°C, < 20 µA @ 125°C) and exhibits reduced junction capacitance (15 pF @ 1 MHz, 4 V) versus lower-voltage variants-critical for minimizing switching node ringing in SMPS topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports 400 V DC-link applications with 1.5× safety margin |
| IF | 1 A continuous - suitable for medium-power DC-DC outputs up to ~12 W at 12 V |
| trr | ≤35 ns - enables efficient operation in 100–500 kHz switch-mode converters |
| VF @ 1 A, 25°C | 1.15 V (typ), 1.70 V (max) - defines conduction loss and thermal rise under load |
| CJ @ 1 MHz, 4 V | 15 pF - reduces capacitive coupling and EMI in high-dV/dt nodes |
| RθJL | 28 °C/W - allows direct heat transfer to PCB copper, easing thermal design |
| IFSM @ 1.0 ms | 60 A - withstands inrush and short-circuit transients without failure |

Applications
| DC-DC Converter Output Rectification | Switching Inverter Freewheeling Diode |
|---|---|
Use Scenario: Secondary-side rectification in isolated flyback or forward converters delivering 5–24 V at ≤1 A. IC Role / Device Role / Timing Role: Unidirectional current path enabling energy transfer from transformer to output capacitor. Use Value: 1.15 V VF minimizes conduction loss; 35 ns trr suppresses reverse recovery spikes that degrade MOSFET gate drive integrity. | Use Scenario: Freewheeling path across inductive loads (e.g., motor windings or relay coils) in half-bridge inverters. IC Role / Device Role / Timing Role: Provides low-loss current recirculation during high-side switch off-time. Use Value: 600 V VRRM accommodates inductive kickback in 400 V bus systems; 60 A IFSM handles transient overcurrent without degradation. |
| AC-DC Adapter Secondary Rectifier | Industrial Power Supply Snubber Diode |
Use Scenario: Output rectification in universal-input (90–264 V AC) offline adapters powering IoT gateways or sensors. IC Role / Device Role / Timing Role: Converts transformer secondary AC to regulated DC, operating continuously at 1 A. Use Value: 150 °C TJMAX and 20 °C/W RθJC support reliable operation in enclosed, thermally constrained enclosures. | Use Scenario: Clamping diode in RCD snubber networks across MOSFETs in industrial UPS or servo drives. IC Role / Device Role / Timing Role: Absorbs turn-off energy from leakage inductance and resets snubber capacitor. Use Value: 35 ns trr ensures rapid recombination before next switching cycle, preventing snubber inefficiency and voltage overshoot. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | Same 600 V VRRM, 1 A IF, but trr = 50 ns; VF = 1.3 V @ 1 A/25°C; TO-277 package | Higher forward drop and slower recovery increase conduction and switching losses in >200 kHz designs | Prefer ES1JAL where board space and high-frequency efficiency are critical |
| ON Semi MUR160 | 600 V VRRM, 1 A IF, trr = 50 ns; VF = 1.25 V @ 1 A/25°C; SMA package, but larger footprint than Thin SMA | Thicker profile and higher RθJA (75°C/W) limit thermal performance in dense layouts | Choose ES1JAL when low profile and superior thermal resistance (28°C/W vs. ~40°C/W) are required |
Compared with STTH1L06S and MUR160, the ES1JAL delivers faster recovery (35 ns), lower VF at 125°C (0.93 V), and better thermal coupling (RθJL = 28°C/W), making it optimal for space-constrained, high-efficiency 300–500 kHz power stages.

FAQ
What is the maximum junction temperature rating for the ES1JAL?
The ES1JAL has a maximum junction temperature (TJMAX) of +150°C, verified per absolute maximum ratings in the official TSC datasheet. This rating permits reliable operation in ambient environments up to +105°C when mounted on a 5 mm × 5 mm Cu pad, given its RθJA of 67°C/W. Derating curves confirm sustained 1 A current capability up to 125°C case temperature. The ES1JAL must not exceed 150°C at the die to avoid permanent parametric shift or failure.
Does the ES1JAL have a specified moisture sensitivity level (MSL)?
Yes, the ES1JAL is rated MSL Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/85% RH without baking prior to reflow. This classification results from its Thin SMA package construction and moisture-resistant molding compound. No floor life limitation applies, simplifying SMT line logistics. The ES1JAL's MSL Level 1 status is explicitly documented in TSC's C2103 datasheet revision.
What is the reverse recovery time (trr) of the ES1JAL, and under what test conditions is it measured?
The ES1JAL reverse recovery time is ≤35 ns, measured under standardized conditions: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, with a 50% reference point on the reverse current waveform. This value is confirmed in the Electrical Specifications table of the TSC datasheet. The ES1JAL achieves this performance via optimized doping and carrier lifetime control, distinguishing it from slower general-purpose rectifiers.
Can the ES1JAL replace the ES1GAL in a 400 V application without redesign?
No-while both share the same Thin SMA package and pinout, the ES1JAL is rated for 600 V VRRM versus 400 V for the ES1GAL, and exhibits higher forward voltage (1.15 V vs. 0.93 V @ 1 A/25°C). Substituting ES1JAL for ES1GAL introduces unnecessary conduction loss and thermal stress unless the design requires the extra 200 V margin. The ES1JAL is not a drop-in replacement; verify layout, thermal, and efficiency impact before substitution.
Is the ES1JAL halogen-free and RoHS compliant?
Yes, the ES1JAL is certified halogen-free per IEC 61249-2-21 and RoHS compliant, as stated in the Features section of TSC's official datasheet. These compliance attributes are verified through material declarations and third-party testing. The ES1JAL meets EU Directive 2011/65/EU and is suitable for consumer, industrial, and automotive-qualified end equipment where substance restrictions apply.
