Product details
Overview
1.5KE62CA from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 62 V, working stand-off voltage 50.2 V, clamping voltage 89.0 V at 17 A peak pulse current, and junction temperature range −55 °C to +175 °C - used for ESD and surge protection in automotive power supplies and industrial control inputs.
For engineers reviewing the 1.5KE62CA datasheet, 1.5KE62CA pinout, 1.5KE62CA application, or 1.5KE62CA equivalent, this page delivers verified electrical specs, bidirectional clamping behavior, ISO 7637-2 compliance, thermal derating curves, and real-world selection guidance for high-energy transient suppression in harsh environments.
Technical Context
The 1.5KE62CA is a silicon avalanche diode designed for unidirectional or bidirectional transient suppression. Its bidirectional configuration enables symmetrical clamping across both polarities without external polarity management, and it meets ISO 7637-2 Pulse 1/2a/2b/3a/3b immunity requirements for automotive electronics.
It operates with low dynamic impedance and fast response time (<5.0 ns for bidirectional mode), delivering stable clamping performance under 10/1000 μs surge waveforms. The device sustains 1500 W peak pulse power at TA = 25 °C and derates linearly above that ambient per published curve (Fig.2).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 55.8 V / 68.2 V @ IT = 1.0 mA - defines reliable avalanche onset window for consistent clamping initiation |
| VWM | 50.2 V - maximum continuous DC or RMS voltage the device blocks without significant leakage |
| VC @ IPP | 89.0 V @ 17 A - clamped voltage during 10/1000 μs surge, limiting downstream stress to safe levels |
| PPK | 1500 W - peak surge power handling capability, enabling protection against high-energy transients |
| Junction Temp Range | −55 °C to +175 °C - supports operation in under-hood automotive and industrial environments |
| Leakage Current | <1 μA @ VWM - ensures minimal standby power loss and signal integrity in high-impedance circuits |
| Response Time | <5.0 ns (bidirectional) - enables effective suppression of fast EFT and ESD events before IC damage occurs |
Pinout & Package
Package: DO-201 axial-leaded plastic case with pure tin-plated leads, UL 94V-0 rated molding compound, and cathode band marking for unidirectional variants (not applicable to 1.5KE62CA as bidirectional part).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Transient current entry (negative polarity) | One terminal of symmetrical avalanche junction; accepts reverse surge current during negative transients |
| Cathode (Lead 2) | Transient current entry (positive polarity) | Second terminal of symmetrical junction; accepts forward surge current during positive transients |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR and VC characteristics in both directions - eliminates need for polarity-aware board layout |
| ISO 7637-2 compliance | Validated against Pulse 1 (inductive load dump), Pulse 2a/2b (battery disconnect), and Pulse 3a/3b (switching noise) - suitable for automotive ECUs |
| AEC-Q101 qualification | Stress-tested for automotive reliability including temperature cycling, HTRB, and mechanical shock - qualified for under-hood use |
| Low dynamic impedance | Enables tight clamping voltage margin (VC − VBR ≈ 23 V) - reduces overvoltage exposure to protected ICs |
| Halogen-free & RoHS | Complies with IEC 61249-2-21 and EU RoHS Directive - meets environmental compliance for global OEMs |
Applications
| Automotive Power Input Protection | Industrial PLC Digital I/O Protection |

IC Role / Device Role / Timing Role: Fast-response bidirectional shunt across sensor supply and ground pins. Use Value: Sub-5 ns response captures ESD events before propagation, and 50.2 V VWM allows compatibility with 3.3 V–48 V sensor rails. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ64CA | 600 W rating, SMA package (smaller footprint), VC = 103 V @ 9.2 A | Lower power handling; suited for space-constrained consumer electronics, not automotive load dump | Select when board area is critical and surge energy is ≤600 W; verify thermal pad design for SMA mounting |
| ON Semiconductor 1.5SMC68CA | Same 1500 W rating, SMC package (surface-mount), VC = 98 V @ 15.3 A | No axial leads; requires rework of PCB layout and solder profile for SMT assembly | Choose for automated manufacturing where DO-201 through-hole is incompatible; confirm 98 V clamping meets system margin |
Compared with 1.5KE62CA, SMAJ64CA offers smaller size but lower surge capacity and higher clamping voltage, while 1.5SMC68CA matches power rating but shifts to surface-mount - making 1.5KE62CA optimal for high-reliability through-hole designs needing proven AEC-Q101 qualification and lowest clamping voltage in its class.

FAQ
What is the clamping voltage of the 1.5KE62CA under a standard 10/1000 μs surge?
The 1.5KE62CA has a maximum clamping voltage (VC) of 89.0 V at 17 A peak pulse current under the 10/1000 μs waveform. This value is measured per JEDEC standards and reflects the upper limit of voltage imposed on protected circuitry during worst-case surge conditions - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the 1.5KE62CA unidirectional or bidirectional, and how does that affect circuit placement?
The 1.5KE62CA is a bidirectional TVS diode, meaning it provides symmetrical clamping for both positive and negative transients without polarity sensitivity. Unlike unidirectional variants (e.g., 1.5KE62A), it requires no orientation during placement and can be installed across any two nodes needing balanced overvoltage protection - such as power-to-ground or differential signal pairs.
Does the 1.5KE62CA meet automotive qualification standards?
Yes, the 1.5KE62CA is AEC-Q101 qualified (as indicated by the "H" suffix option in ordering codes) and validated for automotive use. It complies with ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b test profiles, and undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias (HTRB), and mechanical shock - confirming suitability for engine control units and body electronics.
What is the maximum steady-state power dissipation for the 1.5KE62CA at elevated temperatures?
The 1.5KE62CA has a steady-state power dissipation (PD) of 5 W at lead temperature (TL) = 75 °C with 0.375" (9.5 mm) lead length on a 0.6" × 0.6" copper pad. Derating follows the published curve (Fig.2): at 125 °C ambient, usable PD drops to ~2.5 W - essential for thermal design in enclosed automotive enclosures.
How does the 1.5KE62CA compare to the 1.5KE62A variant?
The 1.5KE62CA is bidirectional, while 1.5KE62A is unidirectional. Their breakdown voltages differ slightly: 1.5KE62A has VBR = 58.9–65.1 V vs. 1.5KE62CA's 55.8–68.2 V. Clamping voltage also differs - 1.5KE62A is 85.0 V @ 18 A, versus 89.0 V @ 17 A for 1.5KE62CA. Use 1.5KE62CA where polarity-agnostic protection is required; use 1.5KE62A only when directional blocking is needed alongside clamping.
