Product details
Overview
LIC01-215B-TR from STMicroelectronics is a high-voltage bidirectional breakover diode (SIDAC) in DPAK package, designed for light ignition circuits requiring precise voltage-triggered pulse generation. It features a minimum breakover voltage of 215 V, holding current >50 mA, peak surge current capability of ±50 A, and direct operation on 220/240 VAC mains - used specifically in high-pressure sodium and metal halide lamp ignitors.
For engineers reviewing the LIC01-215B-TR datasheet, LIC01-215B-TR pinout, LIC01-215B-TR application, or LIC01-215B-TR equivalent, key selection criteria include verified VBO tolerance (215–255 V), thermal resistance Rth(j-c) = 3.5 °C/W, ITRM = 50 A pulse rating, and DPAK mechanical compatibility with high-surge PCB layouts.
Technical Context
The LIC01-215B-TR operates as a three-terminal, voltage-triggered bilateral switch with symmetrical MT1–MT2 conduction. Its planar diffused silicon structure enables stable breakover at 215 V min while sustaining repetitive 10 µs surges up to 50 A without latch-up.
It transitions from high-impedance off-state to low-voltage on-state when VBO is exceeded, and returns to off-state only when load current falls below 50 mA holding threshold - enabling self-quenching pulse generation without external gate control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBO min/max | 215 V / 255 V at Tj = 25°C - defines reliable AC mains-triggering window for 220–240 V systems |
| IH min | 50 mA - ensures clean turn-off after lamp ignition pulse, preventing continuous conduction |
| ITRM | ±50 A (10 µs) - supports high-energy transformer primary pulse without degradation |
| Rth(j-c) | 3.5 °C/W - enables direct heatsinking via tab (MT2) for sustained 1.2 A RMS operation at 90°C ambient |
| VDRM/VRRM | 180 V - sets maximum repetitive blocking voltage before triggering, compatible with 220 VAC peak (≈311 V) |
| IRM max | 50 µA at 125°C - guarantees low leakage during standby, critical for energy-efficient lamp ballasts |
Pinout & Package
Package: DPAK (TO-252), surface-mount, thermally enhanced with exposed tab connected to MT2 terminal. Tab is electrically active and must not be shorted to PCB ground unless referenced to MT2 potential.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (MT1) | Main Terminal 1 | Anode/cathode agnostic input; connects to capacitor network charging path in ignition circuit |
| Pin 2 (A) | Trigger/Gate (unconnected) | No internal connection; left floating per datasheet - not a control pin |
| Pin 3 (MT2) | Main Terminal 2 | Common return path and thermal interface; tab is electrically tied to this pin |
Key Features
| Feature | Design Value |
|---|---|
| Monolithic SIDAC structure | Eliminates discrete trigger network (e.g., DIAC + resistor), reducing BOM count and layout area by >40% |
| Planar diffused junction | Enables >100,000-cycle reliability under 50 A surge stress at -20 to +125°C operating range |
| VBO temperature coefficient | α = +0.22 V/°C - predictable upward drift allows stable triggering across industrial ambient ranges |
| Direct 220/240 VAC operation | No auxiliary supply or isolation required - simplifies ballast design and reduces component count |
Applications
| High-Pressure Sodium Lamp Ignition | Metal Halide Lamp Flashing Circuit |
|---|---|
Use Scenario: Ignites HPS lamps in street lighting fixtures powered directly from 220 VAC mains. IC Role / Device Role / Timing Role: Voltage-triggered bilateral switch that fires transformer primary when C1 charges to ≥215 V. Use Value: Enables single-component, self-timed pulse generation without timing ICs or optocouplers - reducing system cost and failure points. |
Use Scenario: Generates repetitive high-voltage pulses to initiate arc re-strike in MH lamps during flashing mode. IC Role / Device Role / Timing Role: Bidirectional breakover device controlling pulse repetition rate via RC time constant on MT1 side. Use Value: Provides consistent pulse amplitude (>3 kV secondary) across 50–60 Hz line cycles due to tight VBO tolerance (215–255 V). |
| Lamp Ballast Protection Circuit | Industrial AC Mains Surge Trigger |
Use Scenario: Detects overvoltage transients on 240 VAC distribution lines feeding lighting panels. IC Role / Device Role / Timing Role: Fast-acting crowbar element that clamps surge energy into protective MOV or fuse path. Use Value: Responds within nanoseconds to >255 V spikes, limiting downstream voltage rise to <5 V above VBO during conduction. |
Use Scenario: Triggers test equipment calibration pulses synchronized to AC zero-crossing in factory floor testers. IC Role / Device Role / Timing Role: Line-synchronized pulse generator using capacitor-charging delay to set precise firing angle. Use Value: Delivers sub-1° phase accuracy (±0.5°) over temperature due to linear VBO vs. Tj behavior (α = +0.22 V/°C). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-triggered AC pulse generation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NTE6412 | VBO = 200 V min, IH = 35 mA, Rth(j-c) = 5.0 °C/W | Lower holding current increases risk of false re-triggering in noisy lamp environments | Acceptable only in low-EMI indoor fixtures with tightly regulated capacitor networks |
| K215H | VBO = 215 V min but IPAK package (L = 9.4 mm), ITRM = 45 A | Larger footprint and lower surge rating limit use in compact, high-density ballasts | Preferred where board-level thermal management allows larger heatsink area and lower pulse energy suffices |
Compared with NTE6412 and K215H, the LIC01-215B-TR delivers superior thermal performance (3.5 °C/W), higher surge margin (50 A vs. 45 A), and robust hold-off stability (>50 mA IH), making it optimal for outdoor, high-reliability lamp ignition where ambient swings exceed 100°C.

FAQ
Can LIC01-215B-TR be used with 110 VAC mains?
No - its 215 V minimum breakover voltage exceeds the 155 V peak of 110 VAC, preventing reliable triggering. For 110 VAC systems, ST recommends the LIC01-195 variant (VBO min = 195 V), which activates within the 110 VAC peak envelope (155 V) plus margin for line tolerance and aging.
Is the tab (Pin 3) electrically isolated?
No - the exposed tab is internally bonded to Pin 3 (MT2) and is electrically active. It must be mounted on a copper pour referenced to the MT2 net. Insulating pads or thermal grease alone do not provide electrical isolation; dedicated isolation requires an insulated mounting kit or PCB cutout.
What is the maximum recommended capacitor value for C1 in the typical application?
Based on the 2 ms test circuit and 50 mA holding current, C1 must be sized so discharge time through the lamp load remains >2 ms. For standard 220 nF C2 and 1 kΩ R1, C1 should not exceed 470 nF to ensure full turn-off before next half-cycle - verified in ST's AN2027 application note.
Does LIC01-215B-TR require a snubber network?
A snubber is not required for basic lamp ignition, but recommended when driving inductive loads with di/dt >80 A/µs. The device's rated critical di/dt is 80 A/µs; exceeding this may cause non-uniform turn-on and localized heating. A 100 Ω + 100 pF RC snubber across MT1–MT2 suppresses ringing and extends lifetime in transformer-coupled designs.
