Product details
Overview
BYD17D,115 from NXP Semiconductors (formerly Philips) is a surface-mount controlled avalanche rectifier in SOD87 glass package, rated for 200 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, high-temperature rectifier in flyback snubber networks and inductive load switching circuits.
For engineers reviewing the BYD17D,115 datasheet, BYD17D,115 pinout, BYD17D,115 application, or BYD17D,115 equivalent, key selection criteria include its guaranteed avalanche energy absorption, low leakage (≤1 µA at 200 V, 25 °C), 3 µs reverse recovery time, hermetically sealed Implotec™ glass construction, and compatibility with automated SMT assembly using 8 mm embossed tape.
Technical Context
The BYD17D,115 is engineered for controlled avalanche operation under inductive turn-off stress, enabling reliable clamping without external Zener diodes. Its cavity-free cylindrical glass package matches thermal expansion coefficients across all materials, eliminating fatigue failure modes common in plastic-packaged rectifiers.
It operates with junction temperatures up to +175 °C and maintains stable reverse breakdown at 225 V (V(BR)R, IR = 0.1 mA), supporting designs requiring predictable overvoltage protection in DC-DC converters and relay drivers where transient suppression must be integrated into the rectification path.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage the device sustains without breakdown during normal operation. |
| IF(AV) | 1.5 A at Ttp = 105 °C - Average forward current capability when mounted on standard PCB with ≥40 µm copper, defining continuous power handling. |
| ERSM | 7 mJ - Non-repetitive avalanche energy absorbed during inductive turn-off, enabling use in snubberless relay/contactor drive circuits. |
| V(BR)R | 225 V at IR = 0.1 mA - Reverse breakdown voltage threshold, ensuring precise clamping behavior in overvoltage protection applications. |
| trr | 3 µs - Reverse recovery time measured at IF = 0.5 A → IR = 1 A, supporting moderate-frequency switching (≤100 kHz) in flyback and buck-derived topologies. |
| Rth j-tp | 30 K/W - Thermal resistance from junction to tie-point, critical for estimating temperature rise in thermally anchored SMT layouts. |
| IR | ≤1 µA at VR = 200 V, 25 °C - Low reverse leakage ensures minimal standby power loss in high-impedance bias networks. |
Pinout & Package
Package: SOD87 - Hermetically sealed, cavity-free cylindrical glass package using Implotec™ technology; cathode marked by band; 2-terminal surface-mount outline per IEC 60747-14 and JEDEC DO-213AA.

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, no guaranteed avalanche rating | Higher voltage rating but lower current and no specified ERSM; requires external clamping for inductive loads | Select when higher reverse voltage margin is needed and avalanche energy is managed externally |
| ON Semiconductor MUR120 | 200 V VRRM, 1 A IF(AV), DO-41 package, 50 ns trr, no avalanche specification | Through-hole, faster recovery, but lacks hermetic seal and guaranteed ERSM; unsuitable for high-reliability SMT designs | Select for cost-sensitive through-hole prototyping where avalanche robustness is not required |
Compared with STTH1L06S and MUR120, the BYD17D,115 uniquely combines SMT compatibility, hermetic glass packaging, guaranteed 7 mJ avalanche energy, and 1.5 A average current in a single 200 V device-making it irreplaceable in space-constrained, high-reliability snubber and relay driver applications.

FAQ
What is the maximum junction temperature rating for BYD17D,115?
The BYD17D,115 has a maximum junction temperature (Tj) of +175 °C, validated across its full reverse voltage range per Fig.5 in the original Philips datasheet. This rating enables operation in enclosed industrial enclosures and automotive under-hood environments where ambient temperatures exceed 125 °C. The device maintains stable avalanche characteristics up to this limit, and thermal design must account for Rth j-tp = 30 K/W when anchoring the tie-point to PCB copper.
Does BYD17D,115 have a guaranteed avalanche energy rating?
Yes, the BYD17D,115 is explicitly specified with a non-repetitive peak reverse avalanche energy (ERSM) of 7 mJ under L = 120 mH, Tj = Tj max prior to surge, and VR = VRRMmax conditions. This value is guaranteed per the "Electrical Characteristics" table and distinguishes it from standard rectifiers. Engineers can rely on this rating for snubberless inductive load switching without additional transient voltage suppressors.
What package type does BYD17D,115 use and how is polarity marked?
BYD17D,115 uses the SOD87 surface-mount package-a hermetically sealed, cavity-free cylindrical glass outline defined in IEC 60747-14 and JEDEC DO-213AA. Polarity is indicated by a visible cathode band on the glass body, aligned with the cathode terminal. The package dimensions are D = 2.0 mm, L = 3.5 mm, and H = 2.1 mm, optimized for high-density PCB layouts.
What is the reverse recovery time (trr) of BYD17D,115 and under what test conditions?
The reverse recovery time (trr) of BYD17D,115 is 3 µs, measured under the condition: switched from IF = 0.5 A to IR = 1 A, with measurement taken at IR = 0.25 A per Fig.10 in the Philips datasheet. This value applies at Tj = 25 °C and defines usable switching frequency limits-typically ≤100 kHz in flyback and buck-derived topologies where soft recovery is not required.
Is BYD17D,115 suitable for automotive applications?
Yes, BYD17D,115 is suitable for automotive applications including relay and solenoid drivers, provided ambient temperatures remain within its specified storage (−65 °C to +175 °C) and operating ranges. Its guaranteed 7 mJ avalanche energy, low leakage (≤1 µA at 200 V), and hermetic glass package meet key requirements of ISO 7637-2 pulse 3a/b testing. However, system-level qualification per AEC-Q101 remains the responsibility of the end designer.
