Product details
Overview
1.5KE150CHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 1500 W peak pulse power rating (10/1000 µs), 143 V minimum breakdown voltage (VBR), 128 V maximum standoff voltage (VWM), and clamps transients to ≤207 V at 7.2 A peak pulse current - used in automotive power supply input stages, industrial PLC I/O protection, and telecom DC feed circuits.
For engineers reviewing the 1.5KE150CHE3/54 datasheet, 1.5KE150CHE3/54 pinout, 1.5KE150CHE3/54 application, or 1.5KE150CHE3/54 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, thermal derating behavior, clamping performance curves, and AEC-Q101-qualified alternatives for automotive-grade design-in.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 µA leakage at 128 V), then avalanches sharply at VBR = 143–158 V to divert surge energy away from downstream ICs. Its glass-passivated junction enables sub-nanosecond response time (<1 ns) and low incremental surge resistance, critical for protecting MOSFET gate drivers and microcontroller I/O pins against ESD and lightning-induced transients.
The device complies with JEDEC standard 1.5KE case style, uses matte tin-plated leads solderable per J-STD-002, and supports 275 °C solder dip (10 s). Thermal resistance is RθJA = 75 °C/W and RθJL = 15.4 °C/W, enabling reliable operation up to TJ = 175 °C with appropriate PCB copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 143 V / 158 V - defines precise avalanche onset threshold for repeatable clamping behavior |
| VWM | 128 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | ≤207 V at 7.2 A - clamping voltage during full 1500 W transient, limiting stress on protected circuitry |
| PPPM | 1500 W - peak pulse power handling with 10/1000 µs waveform, validated per REA P.E. 60 |
| IFSM | 200 A - non-repetitive forward surge current rating (8.3 ms half-sine), supports inrush tolerance |
| TJ range | −55 °C to +175 °C - extended temperature capability for under-hood automotive and industrial environments |
| Package | JEDEC 1.5KE - axial-leaded DO-201AD outline, 0.375" lead length, UL 94 V-0 molded epoxy body |
Pinout & Package
JEDEC 1.5KE package: axial-leaded DO-201AD molded epoxy case with cathode band marking. Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102; meets JESD 201 class 1A whisker test (E3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |

IC Role / Device Role / Timing Role: Unidirectional TVS installed across optocoupler input terminals to suppress inductive kickback from solenoid/relay coils. Use Value: Clamps 10/1000 µs surges to ≤207 V within 1 ns, ensuring optocoupler CTR stability and eliminating false triggering. |
| Telecom DC Power Feed Protection | Consumer Appliance Motor Drive Protection |
Use Scenario: Securing −48 V DC feed lines in remote radio head (RRH) base stations against lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Paired unidirectional TVS devices (anode-to-ground, cathode-to-rail) provide bidirectional clamping on telecom power inputs. Use Value: Maintains VWM = 128 V while delivering 1500 W pulse handling - sufficient for ITU-T K.20/21 compliance testing. | Use Scenario: Shielding BLDC motor driver ICs from back-EMF spikes generated during commutation in smart home appliances. IC Role / Device Role / Timing Role: TVS mounted across H-bridge high-side FET source-drain to clamp inductive flyback voltage. Use Value: Withstands 200 A non-repetitive forward surge (8.3 ms), preventing destructive avalanche failure during motor stall events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A-E3/52 | Lower PPPM (600 W), smaller SMB package (surface-mount), VBR = 167–185 V, VC = 243 V @ 2.5 A | Not AEC-Q101 qualified; suited for space-constrained consumer PCBs where 1500 W is not required | Select when board area is limited and surge threat level is below IEC 61000-4-5 Level 3 |
| 1.5KE150AHE3_B | Same 1.5KE package and electrical specs, but AEC-Q101 qualified version with revision code "B" and JESD 201 class 2 whisker test compliance | Approved for automotive under-hood use; identical pinout and thermal profile to 1.5KE150CHE3/54 | Choose for new automotive designs requiring formal qualification evidence and enhanced whisker resistance |
Compared with 1.5KE150CHE3/54, SMBJ150A-E3/52 trades 60 % pulse power and through-hole mounting for compactness, while 1.5KE150AHE3_B matches all key parameters but adds formal AEC-Q101 certification and class 2 whisker resistance - making it the drop-in qualified upgrade path.

FAQ
What is the exact breakdown voltage range for 1.5KE150CHE3/54?
The 1.5KE150CHE3/54 has a guaranteed breakdown voltage (VBR) range of 143 V to 158 V at 1.0 mA test current, measured per JEDEC standard. This tight ±5 % tolerance ensures consistent clamping behavior across production lots and supports predictable system-level surge margin analysis in designs using 1.5KE150CHE3/54.
Is 1.5KE150CHE3/54 AEC-Q101 qualified?
No - 1.5KE150CHE3/54 carries the E3 suffix indicating RoHS-compliant commercial grade construction. For AEC-Q101 qualification, select 1.5KE150AHE3_B, which shares identical electrical specs and package but includes formal automotive qualification and JESD 201 class 2 whisker resistance. 1.5KE150CHE3/54 itself is not certified.
What is the clamping voltage of 1.5KE150CHE3/54 at its rated peak pulse current?
At its rated peak pulse current of 7.2 A (10/1000 µs waveform), the 1.5KE150CHE3/54 clamps to a maximum of 207 V. This value is specified in the Vishay datasheet (document 88301, page 2) and defines the upper voltage limit imposed on protected circuitry during worst-case surge events involving 1.5KE150CHE3/54.
Can 1.5KE150CHE3/54 be used in bidirectional configurations?
No - 1.5KE150CHE3/54 is a unidirectional TVS diode, identifiable by its cathode band marking. Bidirectional variants use the "CA" suffix (e.g., 1.5KE150CA). Using 1.5KE150CHE3/54 in reverse-biased mode risks permanent damage due to lack of symmetric avalanche structure; always verify polarity during layout for 1.5KE150CHE3/54 placement.
What is the thermal resistance of 1.5KE150CHE3/54 and how does it affect PCB layout?
The 1.5KE150CHE3/54 has RθJA = 75 °C/W (junction-to-ambient) and RθJL = 15.4 °C/W (junction-to-lead). To maintain TJ ≤ 175 °C under 6.5 W continuous dissipation, PCB copper pour must provide ≥10 cm² of 2 oz copper connected to both leads. Layouts using 1.5KE150CHE3/54 should avoid narrow traces and maximize thermal relief to prevent thermal runaway.
