Product details
Overview
BR100/03 from Philips Semiconductors is a silicon bidirectional trigger diode (DIAC) in SOD27 glass envelope, designed to initiate conduction in triac and thyristor gate circuits. It features 28–36 V breakover voltage (VBO), 7 V output voltage (VO), 2 A repetitive peak forward current (IFRM), 150 mW total power dissipation, and operates up to 100 °C junction temperature - used in phase-control dimmers and AC motor speed controllers.
For engineers reviewing the BR100/03 datasheet, BR100/03 pinout, BR100/03 application, or BR100/03 equivalent, key selection criteria include verified VBO symmetry (<3.5 V), sub-1.5 µs risetime (tr), thermal resistance (Rth j-a = 330 K/W), IBO ≤ 50 µA, and compatibility with 50/60 Hz AC mains-triggered TRIAC circuits.
Technical Context
The BR100/03 functions as a two-terminal, symmetrical avalanche switch that conducts only after either polarity exceeds its specified breakover voltage. Its bidirectional VBO range (28–36 V) and tight symmetry (≤3.5 V difference between +VBO and –VBO) ensure balanced triggering in AC phase-control topologies.
It delivers a stable 7 V output voltage into a 20 Ω load per test circuit Fig.2, with a typical risetime of ≤1.5 µs at 0.5 A peak current. Its thermal design relies on lead-mounted dissipation (Rth j-lead = 150 K/W) and is rated for operation up to 100 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBO | 28–36 V - defines minimum AC voltage threshold before conduction onset in either polarity |
| |VBO+| − |VBO−| | ≤3.5 V - ensures matched positive/negative triggering for zero-crossing stability in AC control |
| VO | 7 V - clamped output voltage delivered to TRIAC gate under 20 Ω load, enabling reliable firing |
| IFRM | 2 A - peak repetitive forward current rating supports surge-tolerant operation in 50/60 Hz line applications |
| tr | ≤1.5 µs - fast risetime ensures sharp gate pulse delivery to minimize TRIAC turn-on delay jitter |
| Rth j-a | 330 K/W - thermal resistance in free air dictates derating above 50 °C ambient for sustained 150 mW dissipation |
| Tj | 100 °C - maximum allowable junction temperature limits continuous operation in enclosed or high-ambient environments |
Pinout & Package
Package: SOD27 glass axial-lead envelope (24 mm length × 4.5 mm diameter, 1.95 mm max lead diameter). Two-terminal device with no polarity marking; terminals are interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Trigger electrode | Either terminal serves as input; conduction initiates when voltage magnitude exceeds VBO in either direction |
| Lead 1 / Lead 2 | Thermal and electrical path | Leads provide mechanical mounting and primary heat conduction path (Rth j-lead = 150 K/W) |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional symmetry | VBO polarity mismatch ≤3.5 V ensures consistent TRIAC firing across AC half-cycles |
| Controlled output voltage | Stable 7 V output into 20 Ω load provides predictable gate energy for standard triacs |
| Fast switching risetime | ≤1.5 µs enables precise phase-angle control without timing drift in dimmer/motor control |
| High surge current capability | 2 A IFRM rating supports repeated line-voltage transients in 50/60 Hz mains environments |
| Low breakover current | IBO ≤ 50 µA minimizes standby leakage and prevents false triggering in high-impedance gate networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional trigger diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BT151-500R | Higher VBO (45–55 V), TO-92 package, higher IFRM (1 A continuous, 10 A surge) | Used where higher breakover voltage is required to avoid false triggering in noisy 230 V lines | Select BT151-500R when system noise immunity or higher gate drive energy is needed; not drop-in due to different VBO and package |
| DB3 | VBO = 30–35 V (closer match), DO-35 glass package, same 7 V VO, but lower IFRM (1 A) | Common in cost-sensitive consumer dimmers; slightly lower surge tolerance than BR100/03 | DB3 is a functional alternative with near-identical VBO and VO; verify thermal margin if operating above 50 °C ambient |
Compared with BR100/03, BT151-500R offers higher noise immunity but requires layout adaptation, while DB3 matches VBO closely but demands thermal verification under sustained load - both serve distinct trade-offs in reliability, size, and EMI resilience.

FAQ
What is the exact breakover voltage range for BR100/03?
The BR100/03 has a guaranteed breakover voltage (VBO) range of 28 V to 36 V at 25 °C, with a typical value of 32 V. This specification is measured at I = IBO and applies symmetrically to both polarities. The BR100/03 datasheet confirms this range under Quick Reference Data and Characteristics sections, and it is validated by the limiting values table.
Does BR100/03 have polarity markings or directional orientation?
No, the BR100/03 is a truly bidirectional device with no anode/cathode distinction. Its SOD27 glass envelope contains no polarity marking, and either lead may be connected to either side of the triggering network. The BR100/03 conducts identically in both directions once the voltage magnitude exceeds VBO, as confirmed by its symmetrical VBO specification and test circuit Fig.1.
What is the maximum ambient temperature for continuous operation of BR100/03?
The BR100/03 is rated for continuous operation up to 50 °C ambient temperature at full 150 mW power dissipation. Above 50 °C, derating is required per its Rth j-a = 330 K/W thermal resistance. The BR100/03 junction temperature must not exceed 100 °C, and its storage temperature range is –55 °C to +125 °C.
Can BR100/03 directly replace DB3 in existing designs?
The BR100/03 and DB3 share similar VBO (30–35 V vs. 28–36 V) and VO (7 V), but BR100/03 offers higher IFRM (2 A vs. 1 A) and different thermal resistance. While functionally comparable, BR100/03 is not a guaranteed drop-in replacement due to SOD27 vs. DO-35 mechanical differences and higher surge capability - board layout and thermal validation are recommended before substitution.
What test circuit defines the 7 V output voltage (VO) specification for BR100/03?
The 7 V output voltage (VO) of BR100/03 is defined under RL = 20 Ω load using the test circuit shown in Fig.2 of the Philips datasheet: a 100 nF capacitor, 10 kΩ resistor, and 500 kΩ potentiometer feeding the BR100/03, with output measured across the 20 Ω load. This circuit replicates real-world TRIAC gate drive conditions, and the BR100/03 consistently delivers ≥7 V under these conditions.
