Product details
Overview
1.5KE82CARL from STMicroelectronics is a bidirectional Transil™ TVS diode designed for high-energy transient voltage suppression in DC power lines and signal interfaces. It delivers 1500 W peak pulse power (10/1000 µs), has a breakdown voltage of 77.9 V (min) to 86.1 V (max) at 1 mA, clamps transients to ≤113 V at 13.3 A, and operates across –65 °C to +175 °C - used in industrial power supply input protection.
For engineers reviewing the 1.5KE82CARL datasheet, 1.5KE82CARL pinout, 1.5KE82CARL application, or 1.5KE82CARL equivalent, key selection criteria include clamping voltage vs. peak current, unidirectional/bidirectional configuration, junction-to-lead thermal resistance (20 °C/W), and UL 497B certification for telecom surge protection compliance.
Technical Context
This device functions as a voltage-clamping transient suppressor using avalanche breakdown in silicon PN junctions. Its bidirectional structure enables symmetrical clamping on both polarities without external series components, supporting AC-coupled or floating bus protection.
It responds within <1 ns to ESD and lightning-induced surges, with low dynamic impedance (13.3 Ω typical at IPP = 13.3 A) and a voltage temperature coefficient of +10.5 mV/°C - enabling predictable clamping shift over operating temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500 W (10/1000 µs waveform): sustains single high-energy surges per IEC 61000-4-5 Level 4 without failure. |
| Breakdown Voltage | 77.9 V (min) to 86.1 V (max) @ 1 mA: defines minimum voltage at which avalanche conduction begins under DC bias. |
| Clamping Voltage | 113 V @ 13.3 A (10/1000 µs): maximum voltage seen by protected circuit during rated surge event. |
| Stand-off Voltage | 82 V (nominal): maximum continuous reverse voltage before significant leakage occurs. |
| Junction Temp Limit | 175 °C: sets maximum allowable die temperature during surge or steady-state operation. |
| Leakage Current | 1 µA @ 82 V: ensures minimal power loss and signal integrity in high-impedance circuits. |
| Capacitance | 1350 pF @ 0 V, 1 MHz: impacts high-frequency signal integrity; halved for bidirectional configuration in AC paths. |
Pinout & Package
DO-201 package: axial-leaded, epoxy-molded, lead-free, UL94 V0 compliant. Dimensions: 8.5–9.5 mm length (A), 25.4 mm lead spacing (B), 4.8–5.3 mm body diameter (C), 0.96–1.06 mm lead diameter (D).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Current entry point in forward bias; common terminal in bidirectional mode | Connected to line or signal path requiring clamping; symmetric with cathode for AC applications. |
| Cathode (Lead 2) | Current exit point in forward bias; common terminal in bidirectional mode | Paired with anode to form bidirectional clamp; no polarity assignment required in PCB layout. |
Key Features
| Feature | Design Value |
|---|---|
| Low clamping factor (VCL/VBR ≈ 1.45) | Minimizes overvoltage stress on downstream MOSFETs and logic ICs during surge events. |
| UL 497B certified (QVGQ2.E136224) | Validates suitability for primary-side telecom and data line surge protection per industry safety standards. |
| Fast response time (<1 ns) | Engages before sensitive circuitry experiences damaging voltage overshoot from ESD or fast transients. |
| Junction-to-lead thermal resistance | 20 °C/W enables efficient heat transfer to PCB copper or heatsink during repetitive surge conditions. |
| Bidirectional symmetry | Eliminates need for polarity-aware placement or external diode bridges in AC or differential signal lines. |
Applications
| Industrial Power Input Protection | RS-485 Data Line Surge Suppression |
|---|---|
Use Scenario: 24 V DC industrial PLC power input exposed to load dump and inductive switching transients. IC Role / Device Role / Timing Role: Primary clamping element placed between VIN and GND, absorbing >1 kV spikes before they reach DC-DC converters. Use Value: Limits voltage to ≤113 V during 13.3 A surge, protecting 36 V-rated input stages and meeting IEC 61000-4-5 Level 3 immunity. |
Use Scenario: Two-wire RS-485 bus in factory automation subject to ground potential differences and lightning coupling. IC Role / Device Role / Timing Role: Bidirectional TVS pair (A/B lines to GND) providing symmetrical clamping without polarity constraints. Use Value: Clamps ±113 V transients while maintaining <1350 pF capacitance to preserve signal integrity up to 10 Mbps. |
| AC Adapter Secondary-Side Protection | Automotive Body Control Module Inputs |
Use Scenario: 12 V output rail of wall-mounted AC/DC adapter subjected to capacitive discharge and cable ESD. IC Role / Device Role / Timing Role: Standoff-rated TVS connected across output terminals to shunt transients before reaching connected devices. Use Value: Withstands 1500 W surges and maintains <1 µA leakage at 82 V, avoiding battery drain in always-on systems. |
Use Scenario: 12 V sensor inputs (e.g., door switch, ambient light) in non-AEC-Q200 BCM modules. IC Role / Device Role / Timing Role: Low-leakage transient suppressor placed at connector interface to absorb ISO 7637-2 pulse 1/2a/3a energy. Use Value: Delivers 113 V clamping at 13.3 A with 175 °C max junction rating, supporting under-hood thermal environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ85CA | Lower peak power (600 W), smaller SMB package (vs. DO-201), higher clamping ratio (VCL/VBR ≈ 1.55) | Better suited for space-constrained PCBs but less robust for repeated high-energy surges | Select when board area is critical and surge duty cycle is low (e.g., consumer USB ports) |
| 1.5SMC82CA | Same 1500 W rating, SMC package (surface-mount), slightly higher clamping voltage (118 V @ 12.7 A) | Enables automated assembly and improved thermal coupling to PCB copper, but requires reflow-compatible layout | Prefer for high-volume production where pick-and-place and thermal performance outweigh through-hole reliability needs |
Compared with 1.5KE82CARL, SMBJ85CA trades surge robustness for compactness, while 1.5SMC82CA matches power handling in a surface-mount format - choice depends on assembly method, thermal management strategy, and surge repetition requirements.

FAQ
What is the maximum surge current 1.5KE82CARL can handle?
1.5KE82CARL handles up to 13.3 A peak pulse current under the standard 10/1000 µs waveform, corresponding to its 1500 W rating. At lower pulse durations (e.g., 8/20 µs), it supports higher peak currents - 146 A - as confirmed in Table 3 of ST's Doc ID 2913 Rev 4.
Is 1.5KE82CARL RoHS and lead-free compliant?
Yes. The device uses a lead-free package compliant with RoHS Directive 2011/65/EU and meets STMicroelectronics' ECOPACK® environmental specifications. The DO-201 housing is epoxy-based and certified UL94 V0 for flammability resistance.
How does the bidirectional configuration affect circuit layout?
The bidirectional design eliminates polarity sensitivity: either lead may connect to line or ground without functional impact. This simplifies layout on AC-coupled buses like RS-485 or Ethernet PHY interfaces and avoids orientation errors during manual assembly.
Can 1.5KE82CARL be used in parallel for higher surge capacity?
No - paralleling discrete TVS diodes causes current imbalance due to parameter spread (e.g., VBR tolerance ±5%). ST does not recommend parallel use. For higher energy handling, select a single higher-rated device such as 3KP82CA (3000 W) or verify derating with thermal modeling.
