Product details
Overview
LIC01-215H from STMicroelectronics is a high-voltage bidirectional breakover diode (SIDAC) designed for light ignition circuits in high-intensity discharge lamps. It features a minimum breakover voltage of 215 V, holding current >50 mA, peak surge current capability of 50 A, and operates directly from 220/240 VAC mains - used specifically in high-pressure sodium and metal halide lamp ignitors.
For engineers reviewing the LIC01-215H datasheet, LIC01-215H pinout, LIC01-215H application, or LIC01-215H equivalent, key selection criteria include verified VBO tolerance (215–255 V), thermal resistance (Rth(j-c) = 3.5 °C/W), ITRM pulse rating, and IPAK package mechanical compatibility with high-surge lamp ballast PCB layouts.
Technical Context
The LIC01-215H is a three-terminal planar-diffused semiconductor switch that triggers into conduction when voltage across MT1–MT2 exceeds its temperature-dependent breakover threshold (VBO = 215–255 V at 25°C, α ≈ 0.22 V/°C). It remains latched until load current falls below IH ≥ 50 mA.
Its structure supports direct AC mains operation without external gate drive, delivering high di/dt (80 A/µs) and repetitive 10 µs surge pulses up to 50 A. Thermal design relies on low junction-to-case resistance (3.5 °C/W) and rated Tj range of –20 to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBO min/max | 215 V / 255 V at 25°C - defines reliable AC peak-triggering window for 220–240 VAC systems |
| IH min | 50 mA - ensures stable latching during lamp arc sustainment without false turn-off |
| ITRM | ±50 A (10 µs) - enables robust ignition pulse delivery into transformer primary windings |
| Rth(j-c) | 3.5 °C/W - allows direct heatsinking to PCB copper or small metal clips in compact lamp ballasts |
| VDRM/VRRM | 180 V - sets maximum non-triggering blocking capability under transient overvoltage |
| IRM max | 50 µA at 125°C - guarantees low leakage during hot standby, minimizing power loss in series-connected circuits |
Pinout & Package
Package: IPAK (TO-251AA), thermally enhanced plastic power package with exposed tab (non-electrical, not connected). Mounting requires isolation from heatsink unless tab is electrically tied to MT2 per layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (MT1) | Main Terminal 1 | Anode-side terminal; connects to AC line or capacitor network; polarity-agnostic due to bidirectional symmetry |
| Pin 2 (A) | Trigger/Gate Analog | Internal trigger node - not externally accessible; device is two-terminal functional despite 3-pin package |
| Pin 3 (MT2) | Main Terminal 2 | Cathode-side terminal; typically tied to transformer primary ground or return path; tab is internally connected to MT2 |
Key Features
| Feature | Design Value |
|---|---|
| Monolithic high-surge SIDAC structure | Enables single-device replacement of discrete SCR+trigger circuit in lamp ignitors, reducing BOM count and board space |
| Planar-diffused junction | Delivers ruggedness against repeated 50 A surges and operation in humid, high-temperature lamp enclosures |
| Direct 220/240 VAC mains interface | Eliminates need for step-down transformers or isolated gate drivers in cost-sensitive lighting ballasts |
| Temperature-stable VBO | Drift coefficient α = 0.22 V/°C ensures consistent firing timing across –20°C to +125°C ambient |
Applications
| High-Pressure Sodium Lamp Ignition | Metal Halide Lamp Flashing Circuit |
|---|---|
Use Scenario: Igniting HPS lamps in street lighting fixtures powered by 220–240 VAC mains with magnetic or electronic ballasts. IC Role / Device Role / Timing Role: Bidirectional breakover switch triggering high-voltage pulse into ignition transformer primary upon capacitor voltage rise. Use Value: Enables reliable cold-start within 1–2 seconds using only passive R-C network and no active control IC. | Use Scenario: Generating repetitive flash pulses for advertising or signaling metal halide lamps in commercial signage. IC Role / Device Role / Timing Role: Self-oscillating relaxation switch controlling charge/discharge cycle of timing capacitor to produce periodic HV pulses. Use Value: Provides deterministic flash rate (adjustable via R-C values) without microcontroller or timer IC. |
| Lamp Ballast Protection Interface | AC Mains Surge-Triggered Safety Cut-off |
Use Scenario: Integrating into electronic ballasts where lamp end-of-life detection must trigger open-circuit protection. IC Role / Device Role / Timing Role: Voltage-sensing latch that fires when lamp arc fails and voltage rises above VBO, diverting current to disable output stage. Use Value: Prevents transformer saturation and MOSFET failure during lamp open-circuit fault conditions. | Use Scenario: Detecting lightning-induced overvoltage transients on 240 VAC distribution lines feeding outdoor lighting. IC Role / Device Role / Timing Role: Fast-acting crowbar element that shorts line-to-neutral when transient exceeds 255 V peak, clamping downstream voltage. Use Value: Complements MOV-based protection with precise, repeatable breakdown and self-recovery after transient decay. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage breakover diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BT134-600E | Triac with gate control; requires external trigger circuit; VDRM = 600 V; IT(RMS) = 4 A | Not self-triggering - needs timing IC or optocoupler; suited for phase-controlled dimming, not passive ignition | Select only if active gate drive and dimming capability are required alongside ignition function |
| K2200S | SIDAC with VBO = 220 V (min), IH = 150 mA, TO-92 package, Rth(j-a) = 100 °C/W | Lower surge rating (ITRM = 12 A); unsuitable for direct mains pulse generation without derating | Acceptable only in low-power flashing circuits with heatsink and <10 A peak demand |
Compared with BT134-600E and K2200S, the LIC01-215H uniquely combines self-triggering behavior, 50 A surge capability, and IPAK thermal performance - making it the only drop-in solution for compact, transformer-coupled HID lamp ignitors operating directly from 220–240 VAC.

FAQ
What is the function of Pin 2 on the LIC01-215H?
Pin 2 is an internal connection to the trigger structure and is not externally accessible or usable. The device functions as a two-terminal device between MT1 (Pin 1) and MT2 (Pin 3); Pin 2 serves only mechanical and thermal roles in the IPAK package and must remain unconnected in circuit layout.
Can the LIC01-215H replace a standard DIAC in lamp ignitor designs?
Yes - it is a direct functional upgrade to legacy DIACs like DB3, offering higher VBO precision (215–255 V vs. ±30 V tolerance), 10× higher ITRM (50 A vs. ~5 A), and improved thermal robustness. No circuit modification is needed beyond verifying R-C timing network values for exact firing point.
Is the tab on the IPAK package electrically connected?
Yes - the exposed tab in the LIC01-215H IPAK package is internally connected to MT2 (Pin 3). When mounting to a heatsink, electrical isolation is required unless MT2 is referenced to system ground; otherwise, short-circuit risk exists.
How does junction temperature affect breakover voltage stability?
VBO increases linearly with junction temperature at +0.22 V/°C. At 125°C, VBO rises ~23 V above its 25°C value - e.g., 215 V min becomes ~238 V. This positive TC ensures safe margin against false triggering during thermal stress in enclosed luminaires.
