Product details
Overview
1.5KE220 from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with 220V nominal breakdown voltage (VBR = 198–242 V @ 1.0 mA), 175 V working stand-off voltage (VWM), and 344 V maximum clamping voltage (VC) at 4.5 A peak impulse current. It protects automotive power rails and industrial I/O interfaces against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE220 datasheet, 1.5KE220 pinout, 1.5KE220 application, or 1.5KE220 equivalent, key selection criteria include clamping performance under 10/1000 µs surge, junction temperature rating up to +175°C, AEC-Q101 qualification status, DO-201 mechanical compatibility, and leakage current <1 µA above 10 V.
Technical Context
The 1.5KE220 operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 198–242 V breakdown range. Its low dynamic impedance ensures rapid energy diversion during transients, while the 344 V clamping voltage limits downstream stress during 4.5 A 10/1000 µs surges.
Designed for high-energy pulse suppression, it sustains 1500 W non-repetitive peak power per JEDEC standard, derates linearly above 25°C ambient, and maintains stable VBR with 0.110 %/°C temperature coefficient. It meets ISO 7637-2 immunity requirements without external biasing or control circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT = 1.0 mA | 198–242 V - defines precise avalanche initiation threshold for overvoltage detection and clamping onset |
| VWM | 175 V - maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPP = 4.5 A | 344 V - peak clamped voltage seen by protected circuit during standardized 10/1000 µs surge |
| PPK | 1500 W - non-repetitive surge power handling capability per JEDEC test waveform Fig.3 |
| TJ max | +175°C - maximum junction temperature enabling operation in under-hood automotive and industrial environments |
| ID @ VWM | <1 µA - ultra-low leakage preserves signal integrity and minimizes standby power loss |
| Package | DO-201 - industry-standard axial-leaded package with UL 94V-0 molding compound and tin-plated leads |
Pinout & Package
DO-201 package: axial-leaded, cylindrical epoxy body with cathode band marking polarity. Cathode terminal is marked with a band; anode is unmarked lead. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for unidirectional clamping | Connected to ground or low-side return path; establishes reference for reverse-biased operation |
| Cathode | Transient input / protected line connection | Connected to line being protected (e.g., 24 V rail); conducts avalanche current to anode during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified option available | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification |
| 10/1000 µs surge rating | 1500 W peak power handling enables protection against severe load-dump and inductive-switching transients |
| Clamping voltage ≤344 V | Ensures downstream 200 V-rated components remain within safe operating area during worst-case surge events |
| Leakage current <1 µA @ VWM | Minimizes quiescent current draw and avoids false triggering in high-impedance sensing circuits |
| ISO 7637-2 compliance | Validated for Pulse 1 (inductive load disconnect), Pulse 2a/2b (switching transients), and Pulse 3a/3b (line capacitance discharge) |
Applications
| Automotive Power Rail Protection | Industrial PLC Digital Input Protection |
|---|---|
Use Scenario: 24 V battery-fed control modules exposed to load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp transients before they reach DC-DC converters and microcontrollers. Use Value: Limits rail voltage to ≤344 V during 1500 W surges, preventing latch-up or permanent damage to 36 V-input regulators and CAN transceivers. |
Use Scenario: 24 V digital input channels on programmable logic controllers subjected to field-wiring ESD and inductive kickback. IC Role / Device Role / Timing Role: Front-end protection device mounted directly at connector entry point, shunting fast transients to common ground. Use Value: Responds in <1 ps to sub-nanosecond ESD events and clamps 10/1000 µs inductive spikes to safe levels for optocoupler input stages. |
| Telecom Power Supply Surge Suppression | Motor Drive Control Signal Protection |
Use Scenario: -48 V DC telecom power distribution boards encountering lightning-induced surges on long-line feeds. IC Role / Device Role / Timing Role: Primary-level unidirectional TVS on input bus, coordinated with MOVs and gas discharge tubes in multi-stage architecture. Use Value: Provides precise 175 V standoff and 344 V clamping to protect upstream rectifiers and downstream PMICs without premature conduction. |
Use Scenario: Isolated gate drive signals for IGBTs in variable-frequency drives exposed to cross-talk and ground bounce. IC Role / Device Role / Timing Role: Low-capacitance TVS on logic-level signal lines (e.g., PWM inputs) referenced to local ground plane. Use Value: Maintains signal integrity with <1 µA leakage and fast response, preventing false triggering of gate drivers during system-level EFT bursts. |
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 SMAJ220A | Same DO-214AC (SMA) package; lower PPK (400 W); VBR = 244–269 V; VC = 356 V @ 1.1 A | Lower surge rating suits consumer-grade 24 V systems; not AEC-Q101 qualified | Select when board space constraints favor surface-mount and surge energy is ≤400 W |
| ON Semiconductor 1N6297A | Same DO-201 package; identical VBR (108–132 V) and VC (173 V) but for 120 V nominal; not rated for 220 V operation | Not electrically interchangeable - designed for lower-voltage rails requiring tighter clamping | Use only for 120 V systems; 1.5KE220 remains required for 220 V nominal applications |
Compared with SMAJ220A, the 1.5KE220 delivers 3.75× higher surge power handling and AEC-Q101 qualification, making it suitable for harsh automotive environments; compared with 1N6297A, it provides correct 220 V clamping headroom essential for 200–240 V industrial mains-connected equipment.

FAQ
What is the breakdown voltage range of the 1.5KE220?
The 1.5KE220 has a guaranteed breakdown voltage (VBR) range of 198 V to 242 V when tested at 1.0 mA DC current, per JEDEC specification. This range ensures consistent avalanche initiation across manufacturing lots and temperature extremes, and is verified during 100% production testing. The 1.5KE220 uses this precise VBR window to reliably clamp transients above 175 V while remaining fully blocking below that threshold.
Is the 1.5KE220 unidirectional or bidirectional?
1.5KE220 is a unidirectional TVS diode, intended for DC line protection where polarity is fixed. Its cathode band marks the transient input terminal, and it conducts only in reverse bias. Unlike bidirectional variants (e.g., 1.5KE220CA), the 1.5KE220 does not conduct in forward bias beyond typical diode drop and is not rated for AC or bipolar surge suppression.
Does the 1.5KE220 meet AEC-Q101 qualification?
The base 1.5KE220 is not AEC-Q101 qualified; however, the AEC-Q101-compliant variant is designated 1.5KE220H (or 1.5KE220HA0G for ammo pack). This version undergoes full stress testing per AEC-Q101 including HTGB, HTRB, TCT, and ESD, and is documented in Taiwan Semiconductor's qualified parts list. Always verify part suffix when selecting for automotive use.
What is the maximum clamping voltage of the 1.5KE220 under surge conditions?
The 1.5KE220 exhibits a maximum clamping voltage (VC) of 344 V when subjected to a 4.5 A peak impulse current with a 10/1000 µs waveform. This value is measured per JEDEC standard and represents the highest voltage imposed on the protected circuit during worst-case transient events. It ensures compatibility with 400 V-rated downstream components while maintaining margin for voltage overshoot.
Can the 1.5KE220 be used in place of the 1.5KE200 or 1.5KE250?
No - the 1.5KE220 is not interchangeable with 1.5KE200 or 1.5KE250 due to distinct VBR and VWM specifications: 1.5KE200 has VBR = 180–220 V and VWM = 162 V, while 1.5KE250 has VBR = 225–275 V and VWM = 202 V. Substituting the 1.5KE220 would result in either premature clamping (if replacing 1.5KE250) or insufficient protection margin (if replacing 1.5KE200), compromising system reliability.
