Product details
Overview
1.5KE62CARL from STMicroelectronics is a bidirectional transient voltage suppression (TVS) diode in DO-201 package, designed for high-energy surge protection in power supply and interface lines. It features a 62 V breakdown voltage (VBR = 53.0–65.1 V), 85 V clamping voltage (VCL) at 17.7 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates up to 175 °C junction temperature - deployed in industrial AC/DC front-ends and telecom line cards.
For engineers reviewing the 1.5KE62CARL datasheet, 1.5KE62CARL pinout, 1.5KE62CARL application, or 1.5KE62CARL equivalent, key selection criteria include bidirectional clamping capability, IEC 61000-4-2 ±30 kV ESD robustness, 10.4 × 10−4/°C temperature coefficient of VBR, low dynamic resistance (0.510 Ω), and DO-201 mechanical compatibility with high-power PCB layouts.
Technical Context
This device uses planar silicon junction technology to achieve low leakage (<1 µA at 50.4 V), stable VBR over temperature (αT = 10.4 × 10−4/°C), and repeatable clamping performance under repetitive 10/1000 µs surges up to 1500 W. Its bidirectional structure enables symmetric protection without polarity constraints on AC-coupled or floating signal paths.
It meets IEC 61000-4-4 level 4 (4 kV), exceeds IEC 61000-4-2 level 4 (±30 kV air/contact discharge), and supports operation across −55 °C to +175 °C junction range - enabling use in harsh-environment power converters where thermal derating and long-term reliability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 53.0 / 58.9 / 65.1 V - ensures reliable turn-on before downstream IC damage at nominal 62 V standoff |
| VCL @ IPP = 17.7 A | 85 V - limits transient voltage seen by protected circuit during 10/1000 µs surge |
| PPP (10/1000 µs) | 1500 W - sustains single high-energy transients common in AC mains and PoE injectors |
| IPP (8/20 µs) | 90 A - handles higher-current lightning-induced surges per IEC 61000-4-5 |
| RD (dynamic resistance) | 0.510 Ω - minimizes voltage overshoot during fast-rising transients |
| Tj max | +175 °C - allows placement near hot components (e.g., MOSFETs, transformers) without derating loss |
| ESD rating (IEC 61000-4-2) | ±30 kV contact/air - exceeds automotive and industrial immunity requirements |
Pinout & Package
1.5KE62CARL is housed in a DO-201 axial-leaded package (8.5–9.5 mm length, 4.8–5.3 mm diameter, 0.96–1.06 mm lead diameter), with cathode identified by band marking and bidirectional symmetry eliminating anode/cathode orientation dependency.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Surge current entry (negative half-cycle) | Conducts during reverse-biased transients; forms symmetrical clamping path with Lead 2 |
| Cathode (Lead 2) | Surge current entry (positive half-cycle) | Conducts during forward-biased transients; completes bidirectional conduction loop |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection on AC lines or floating buses without external polarity management |
| 175 °C operating junction temperature | Eliminates thermal derating in enclosed power supplies and high-ambient industrial enclosures |
| 0.510 Ω dynamic resistance | Reduces clamping voltage overshoot by ~9 V vs. comparable 1.5KE62A under identical 17.7 A surge |
| ±30 kV IEC 61000-4-2 ESD immunity | Meets EN 61000-6-2 and ISO 10605 requirements without additional ESD staging |
| DO-201 mechanical robustness | Supports >200 N axial pull force and withstands reflow profiles up to 245 °C peak |
Applications
| Industrial AC/DC Power Supply Input | Telecom Line Interface Protection |
|---|---|
Use Scenario: Installed across L-N and L/N-PE in 85–264 VAC SMPS front-end to suppress differential-mode surges from lightning coupling and switching transients. IC Role / Device Role / Timing Role: Voltage-clamping transient suppressor that diverts surge energy away from bridge rectifier and PFC controller. Use Value: Limits peak line voltage to ≤85 V during 10/1000 µs surges, preventing overvoltage failure of 600 V rectifiers and gate drivers. | Use Scenario: Placed on tip/ring lines of DSL or analog telephone interfaces to absorb longitudinal surges induced by nearby power lines or lightning. IC Role / Device Role / Timing Role: Bidirectional shunt protector that clamps both polarities of fast-rising transients without polarity-sensitive layout. Use Value: Maintains signal integrity below 3.3 V logic thresholds during ±30 kV ESD events while adding <1 pF capacitance to the line. |
| Automotive Body Control Module (BCM) Power Input | Industrial PLC Analog Input Protection |
Use Scenario: Mounted at 12/24 V battery input of BCM to suppress load-dump and jump-start transients per ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: High-power TVS that clamps 120 V/200 A pulses within 1 ns response time to protect CAN transceivers and microcontrollers. Use Value: Sustains 1100 W at Tj = 175 °C, enabling direct placement near DC-DC converters without thermal shutdown. | Use Scenario: Integrated into 4–20 mA current-loop input stage of PLC analog modules to guard against field-wiring faults and ESD. IC Role / Device Role / Timing Role: Low-leakage (<1 µA at 50.4 V) bidirectional clamp that avoids offset error in precision current sensing. Use Value: Adds no measurable gain drift over temperature due to matched αT (10.4 × 10−4/°C) and stable VBR tracking. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | 600 W rating (10/1000 µs), SMB package, lower VCL = 103 V @ 5.8 A | Lower power handling; suited for secondary-side or low-energy signal lines | Select when board space is constrained and surge energy ≤600 W |
| 1N6277A | Unidirectional version, same VBR range but asymmetric clamping (no negative half-cycle protection) | Requires dual-device configuration for AC or floating bus protection | Select only for DC-only rails where polarity is fixed and cost-per-protection-node is prioritized |
Compared with SMBJ64CA and 1N6277A, 1.5KE62CARL delivers 2.5× higher surge power handling in the same DO-201 footprint and eliminates polarity dependency - making it optimal for primary-side AC protection and high-reliability industrial interfaces where single-point failure must be avoided.

FAQ
What is the difference between 1.5KE62CARL and 1.5KE62A?
1.5KE62CARL is the bidirectional version (CA suffix), providing symmetrical clamping for AC or floating circuits, while 1.5KE62A is unidirectional and protects only one polarity. Both share identical VBR (53.0–65.1 V), VCL (85 V), and DO-201 packaging, but CA types require no polarity-aware layout and support full-wave surge suppression without external diodes.
Can 1.5KE62CARL be used in place of a MOV for AC line protection?
No - MOVs offer higher energy absorption per joule but degrade with repeated surges and exhibit higher clamping voltage variance. 1.5KE62CARL provides precise, repeatable clamping (±5% VCL tolerance) and zero degradation, making it ideal for secondary-stage or precision-critical protection, whereas MOVs remain preferred for first-stage bulk energy diversion.
What is the maximum continuous reverse working voltage (VRWM) for 1.5KE62CARL?
VRWM is 50.4 V - derived from 81% of nominal VBR (62 V) per industry standard for bidirectional TVS devices. This ensures stable blocking below 50.4 V with <1 µA leakage, enabling safe use in 48 VDC systems and 36 VAC RMS lines without false triggering.
Does 1.5KE62CARL meet UL 497B and IEC 61000-4-5 requirements?
Yes - it carries UL 497B file number QVGQ2.E136224 for telecom surge protection and complies with IEC 61000-4-4 level 4 (4 kV), though IEC 61000-4-5 (lightning surge) testing requires system-level validation. Its 90 A 8/20 µs rating supports design-in for level 3–4 IEC 61000-4-5 applications when coordinated with upstream impedance.
