Product details
Overview
P6KE68CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on power and signal lines. It features a 68 V breakdown voltage (VBR min/max = 64.6 V / 71.4 V), 92.0 V maximum clamping voltage at 6.5 A peak pulse current (10/1000 μs), and 600 W peak pulse power rating - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the P6KE68CAHE3/54 datasheet, P6KE68CAHE3/54 pinout, P6KE68CAHE3/54 application, or P6KE68CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, DO-15 mechanical compatibility, and verified 175 °C junction temperature rating under transient surge conditions.
Technical Context
This device operates as a voltage-clamped shunt protector: when reverse (or forward, in bidirectional mode) voltage exceeds VBR, it avalanches into low-impedance conduction to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), critical for suppressing ESD and inductive switching spikes.
Rated for 600 W peak pulse power with 10/1000 μs waveform and 0.01% duty cycle, it sustains repetitive surges only within thermal limits defined by RθJL = 20 °C/W and derating above TA = 25 °C. The absence of polarity marking confirms its bidirectional construction, distinguishing it from unidirectional variants like P6KE68A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 64.6 V / 71.4 V at 1.0 mA test current - defines precise avalanche onset threshold for reliable clamping initiation |
| VWM | 58.1 V - maximum continuous working voltage before leakage exceeds 1.0 μA; sets safe operating margin below VBR |
| VC @ IPPM | 92.0 V at 6.5 A (10/1000 μs) - actual worst-case clamped voltage seen by protected circuit during rated surge |
| PPPM | 600 W - peak transient energy handling capacity; determines survivability against lightning or load-dump events |
| TJ max. | +175 °C - enables operation in under-hood automotive environments and high-ambient industrial enclosures |
| RθJL | 20 °C/W - quantifies thermal path efficiency from junction to lead; informs heatsinking requirements for repeated surges |

Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, epoxy-molded case with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102. No polarity marking - bidirectional symmetry confirmed per datasheet note.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | Either lead serves as input/output; no cathode band - enables placement flexibility in AC or floating signal paths |
| Lead 1 / Lead 2 | Current conduction path | Leads carry full IPPM (6.5 A) during clamping; solderable per JESD 22-B106 (275 °C, 10 s max) |

Use Scenario: Shields primary-side controller ICs and optocoupler inputs in offline AC/DC adapters against line-to-line and line-to-ground surges. IC Role / Device Role / Timing Role: Secondary-side clamp on VCC rail derived from auxiliary winding, limiting startup and fault overvoltage. Use Value: 175 °C TJ max supports compact, thermally constrained adapter designs; AEC-Q101 grade adds robustness for premium consumer products. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | DO-214AA package; 64 V VWM, 104 V VC @ 5.8 A; same 600 W rating but higher clamping voltage | Surface-mount alternative for space-constrained PCBs; requires rework of layout and thermal relief design | Select when SMT assembly and reduced height are prioritized over through-hole serviceability and lead thermal mass |
| 1.5KE68CA | Same DO-15 package; 68 V VBR; 1500 W PPPM rating; higher IPPM (13.3 A) and VC (115 V) | Higher-energy surge handling for industrial motor drives or generator excitation circuits where 600 W is insufficient | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4 and clamping voltage margin permits 115 V |
Compared with SMBJ64CA and 1.5KE68CA, P6KE68CAHE3/54 offers optimal balance of low clamping voltage (92.0 V), AEC-Q101 qualification, and proven DO-15 reliability - making it preferred for cost-sensitive automotive and industrial applications where 600 W suffices and through-hole mounting is acceptable.

FAQ
What is the clamping voltage of P6KE68CAHE3/54 under standard surge conditions?
The P6KE68CAHE3/54 has a maximum clamping voltage (VC) of 92.0 V when subjected to a 10/1000 μs waveform peak pulse current of 6.5 A. This value is measured per JEDEC standards and represents the upper bound voltage imposed on protected circuitry during a rated transient event - critical for ensuring downstream components remain within their absolute maximum ratings.
Is P6KE68CAHE3/54 suitable for automotive applications?
Yes, P6KE68CAHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its 175 °C maximum junction temperature, glass-passivated junction stability, and validation across temperature cycling, HTRB, and ESD stress make it appropriate for engine control units, body electronics, and ADAS power domains where reliability under harsh thermal and electrical conditions is mandatory.
How does the bidirectional configuration of P6KE68CAHE3/54 affect its circuit implementation?
The bidirectional nature of P6KE68CAHE3/54 means it conducts symmetrically in both polarities - eliminating the need for polarity orientation during placement and enabling use on AC-coupled lines, differential buses (e.g., RS-485), or floating power rails. Unlike unidirectional variants, P6KE68CAHE3/54 has no cathode band marking and provides identical VBR and VC characteristics in either direction.
What is the maximum continuous reverse voltage rating for P6KE68CAHE3/54?
The maximum steady-state reverse voltage (VWM) for P6KE68CAHE3/54 is 58.1 V. At this voltage, reverse leakage current remains ≤1.0 μA at 25 °C - establishing the safe operating ceiling for continuous bias conditions. Exceeding VWM risks premature conduction and accelerated degradation, so design margins must maintain VWM ≥1.1× nominal system voltage.
Does P6KE68CAHE3/54 require heatsinking for standard surge duty cycles?
No additional heatsink is required for single-event or low-duty-cycle surges (≤0.01%) due to the device's RθJL of 20 °C/W and short thermal time constant. However, for repetitive surges above 1 Hz or ambient temperatures exceeding 75 °C, PCB copper area (≥1 cm² per lead) and lead length optimization become essential to maintain TJ ≤175 °C - as defined in Figure 2 and Figure 5 of the Vishay datasheet 88369.
