Product details
Overview
BYD17J,115 from NXP Semiconductors (formerly Philips) is a controlled avalanche rectifier in SOD87 glass package, rated for 600 V repetitive peak reverse voltage (VRRM), 1.5 A average forward current (IF(AV)) at 105 °C tie-point temperature, and 7 mJ non-repetitive reverse avalanche energy (ERSM). It serves as a rugged, surface-mount power rectifier in flyback snubber networks and inductive load switching circuits.
For engineers reviewing the BYD17J,115 datasheet, BYD17J,115 pinout, BYD17J,115 application, or BYD17J,115 equivalent, key selection criteria include its guaranteed avalanche energy absorption, low leakage (≤1 µA at VR = VRRM), fast 3 µs reverse recovery time (trr), and thermal resistance of 30 K/W (junction-to-tie-point), critical for high-reliability industrial power conversion designs.
Technical Context
The BYD17J,115 employs Implotec™ hermetically sealed cavity-free cylindrical glass packaging with matched thermal expansion coefficients, eliminating fatigue failure modes. Its controlled avalanche capability enables reliable clamping during inductive turn-off transients without external suppressors.
It operates with a typical forward voltage of 1.05 V at 1 A and 25 °C, reverse breakdown voltage of 650 V at IR = 0.1 mA, and diode capacitance of 21 pF at 0 V - parameters optimized for high-voltage, medium-current switching applications where stability under thermal stress is essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse voltage the device withstands without breakdown in normal operation |

|---|---|
Use Scenario: Used across MOSFET drain-source in flyback or forward converters to absorb leakage inductance energy during switch turn-off. IC Role / Device Role / Timing Role: Avalanche rectifier providing passive clamping function with precise voltage threshold and energy handling. Use Value: Eliminates need for external RC snubber or TVS, reducing BOM count and improving efficiency by recovering stored energy. | Use Scenario: Placed across relay coils or solenoid windings in PLC I/O modules and industrial controllers. IC Role / Device Role / Timing Role: Controlled avalanche rectifier acting as freewheeling and voltage-clamping element during coil de-energization. Use Value: Prevents voltage spikes >1000 V that could damage driving transistors, extending system lifetime and meeting IEC 61000-4-4 immunity requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar controlled avalanche rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | 600 V VRRM, 1 A IF(AV), TO-277 package, 50 ns trr - faster but lower current and no guaranteed avalanche energy spec | Preferred in space-constrained high-frequency PFC stages where speed outweighs energy handling | Select when trr < 10 ns is required and ERSM > 5 mJ is not mandatory |
| ON Semiconductor MUR160 | 600 V VRRM, 1 A IF(AV), DO-41 package, 75 ns trr - axial leaded, no avalanche rating, higher VF (1.7 V) | Suitable for low-cost, non-critical AC/DC adapters where board space and reliability margins are less constrained | Choose only for legacy through-hole designs; not recommended for surface-mount or high-reliability use |
Compared with STTH1L06S and MUR160, the BYD17J,115 uniquely combines SOD87 surface-mount form factor, guaranteed 7 mJ avalanche energy, and 3 µs trr - making it the only option among the three qualified for high-stress inductive switching in industrial control PCBs requiring both miniaturization and robust transient suppression.

FAQ
What is the maximum junction temperature rating for BYD17J,115?
The BYD17J,115 has a maximum junction temperature (Tj) of +175 °C and a minimum of −65 °C, validated per IEC 60134 limiting values. This wide range supports operation in harsh environments such as motor drive enclosures and automotive under-hood applications. The BYD17J,115 maintains specified electrical characteristics across this full range when mounted per Fig.9 PCB guidelines.
Does BYD17J,115 have a specified reverse recovery time (trr)?
Yes, the BYD17J,115 has a maximum reverse recovery time (trr) of 3 µs, measured under standard conditions: IF = 0.5 A switched to IR = 1 A, with measurement at IR = 0.25 A. This value is confirmed in the Electrical Characteristics table on page 3 of the original Philips datasheet. The BYD17J,115 delivers consistent trr performance due to its controlled avalanche structure and glass-passivated junction.
Is BYD17J,115 compatible with lead-free reflow soldering processes?
Yes, the BYD17J,115's SOD87 glass package is qualified for lead-free reflow soldering per JEDEC J-STD-020. Its hermetic Implotec™ construction withstands peak temperatures up to 260 °C for 10 seconds. The BYD17J,115 requires standard preheat and soak profiles; no special flux or nitrogen atmosphere is needed for reliable joint formation on FR-4 or high-Tg PCBs.
What does "controlled avalanche" mean for BYD17J,115?
"Controlled avalanche" means the BYD17J,115 is designed and tested to safely operate in reverse breakdown mode with predictable voltage clamping and guaranteed energy absorption (7 mJ ERSM). Unlike standard rectifiers, the BYD17J,115 avoids destructive thermal runaway during transient overvoltage events. This behavior is intrinsic to its process and verified per test condition L = 120 mH, Tj = max prior to surge.
How is the cathode identified on BYD17J,115?
The cathode of the BYD17J,115 is marked with a distinct band on the cylindrical glass body, as shown in Figure 1 (Simplified outline) and Package Outline drawing on page 7 of the datasheet. This marking aligns with industry-standard polarity identification for SOD87 devices. When mounted on PCB, the banded end connects to the higher-potential node during reverse bias - confirming correct orientation for avalanche clamping functionality in the BYD17J,115.
