Product details
Overview
1.5KE160CHE3/54 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 152 V to 168 V breakdown voltage range at 1 mA, 136 V maximum standoff voltage, 219 V clamping voltage at 6.8 A peak pulse current, 1500 W peak pulse power rating (10/1000 µs), and operates across –55 °C to +175 °C junction temperature. It is used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the 1.5KE160CHE3/54 datasheet, 1.5KE160CHE3/54 pinout, 1.5KE160CHE3/54 application, or 1.5KE160CHE3/54 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping behavior under surge conditions, thermal resistance data, and AEC-Q101-qualified alternatives - all confirmed from Vishay's official 88301 specification document.
Technical Context
This TVS diode employs a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its unidirectional polarity enables cathode-referenced clamping on positive-going transients, with a 3.5 V forward voltage at 100 A per JEDEC spec.
The device complies with UL 497B recognition (QVGQ2) and meets JESD 201 Class 1A whisker testing (E3 suffix). It is rated for 1500 W peak pulse power with 0.01% duty cycle, derated linearly above 25 °C ambient using a 75 °C/W junction-to-ambient thermal resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 152 V to 168 V at 1 mA - defines minimum clamping onset threshold under controlled test conditions |
| Standoff Voltage VWM | 136 V maximum - ensures no conduction during normal 136 V DC operation |
| Clamping Voltage VC | 219 V at 6.8 A (10/1000 µs) - maximum voltage seen by protected circuit during specified surge |
| Peak Pulse Power PPPM | 1500 W - sustains single 1 ms transient without failure; limited by thermal mass and RθJA = 75 °C/W |
| Junction Temperature Range | –55 °C to +175 °C - supports operation in under-hood automotive and industrial environments |
| Leakage Current ID | 1.0 µA max at 136 V - negligible standby power loss in high-impedance circuits |
| Forward Voltage VF | 3.5 V at 100 A - relevant only during reverse-transient conduction path; confirms low dynamic impedance |
Pinout & Package
Package: JEDEC DO-201AD (Case Style 1.5KE), axial-leaded molded epoxy body with matte tin-plated leads. Complies with UL 94 V-0 flammability rating and RoHS Directive 2011/65/EU.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for unidirectional clamping | Connected to ground or low-side return; absorbs positive transients when cathode is biased above anode |
| Cathode | Transient voltage sensing and clamping node | Connected to protected line (e.g., 136 V rail); conducts when line exceeds VBR, shunting surge to ground |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable VBR tolerance (±5%) and long-term reliability under repeated surge stress |
| 1500 W peak pulse rating (10/1000 µs) | Protects against IEC 61000-4-5 Level 4 surges (4 kV line-earth) when properly mounted with low-inductance layout |
| AEC-Q101 qualified (HE3 variant) | Validated for automotive powertrain and body electronics where qualification evidence is contractually required |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage exposure to downstream ICs compared to MOVs or polymer-based suppressors |
| UL 497B recognized (QVGQ2) | Meets safety agency requirements for telecom and industrial interface protection without additional certification effort |
Applications
| Industrial Motor Drives | Automotive Body Control Modules |

IC Role / Device Role / Timing Role: Parallel-connected TVS on MPPT controller input to absorb fast-rising transients from nearby lightning strikes or grid switching. Use Value: Enables compliance with IEC 61000-4-5 (10/1000 µs, 2 kV) without requiring oversized capacitors or active crowbar circuits. |
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 peak power (600 W), smaller SMB package (vs. DO-201AD), 150 V VBR min, 243 V VC at 2.5 A | Limited to lower-energy surges; unsuitable for IEC 61000-4-5 Level 4 without parallel staging | Select when board space is constrained and surge threat level is ≤ Level 2; verify thermal margin with RθJA = 110 °C/W |
| 1.5KE160AHE3_B | Same electrical specs and DO-201AD package; AEC-Q101 qualified (HE3_B), vs. commercial-grade E3/54 | Approved for automotive production; includes extended reliability testing (HTOL, TC, UHAST) | Choose for OEM automotive programs requiring PPAP documentation and AEC-Q101 traceability; identical pinout and layout |
Compared with 1.5KE160CHE3/54, SMBJ150A-E3/52 offers compactness at the cost of 60% lower surge capacity, while 1.5KE160AHE3_B provides identical protection performance with certified automotive qualification - enabling drop-in replacement where qualification evidence is mandatory.

FAQ
What is the exact breakdown voltage range for 1.5KE160CHE3/54?
The 1.5KE160CHE3/54 has a guaranteed breakdown voltage (VBR) range of 152 V to 168 V measured at 1 mA test current, per Vishay Document Number 88301. This tolerance reflects manufacturing consistency and ensures predictable clamping onset across production lots. The value is confirmed in the Electrical Characteristics table on page 2 of the datasheet.
Is 1.5KE160CHE3/54 AEC-Q101 qualified?
No, 1.5KE160CHE3/54 is not AEC-Q101 qualified. It carries the E3 suffix indicating RoHS-compliant commercial grade. For AEC-Q101 qualification, select 1.5KE160AHE3_B - which shares identical electrical specs and DO-201AD packaging but includes full automotive stress testing and PPAP documentation.
What does the "54" in 1.5KE160CHE3/54 signify?
The "54" in 1.5KE160CHE3/54 is the preferred package code denoting 13-inch diameter paper tape and reel packaging containing 1400 units, per Vishay's Ordering Information table on page 3 of Document 88301. It does not affect electrical performance or qualification status.
How does the clamping voltage of 1.5KE160CHE3/54 compare to its breakdown voltage?
The 1.5KE160CHE3/54 clamps to 219 V at 6.8 A (10/1000 µs waveform), yielding a clamping ratio (VC/VBR) of approximately 1.37. This low ratio indicates efficient voltage limiting - critical for protecting 200 V-rated MOSFETs or 250 V capacitors without excessive overvoltage margin.
Can 1.5KE160CHE3/54 be used in bidirectional configurations?
No, 1.5KE160CHE3/54 is unidirectional only. Bidirectional variants use the "CA" suffix (e.g., 1.5KE160CA). Per Vishay's note on page 1, bidirectional types are available only up to 1.5KE220CA; 1.5KE160CHE3/54 has a color band marking the cathode and must be oriented with cathode toward the protected line.
