Product details
Overview
5KP170AHE3_A/C from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge clamping on power rails and signal lines. It features 170 V standoff voltage (VWM), 189–209 V breakdown voltage (VBR) at 5 mA, 275 V maximum clamping voltage at 18.2 A peak pulse current, and 5000 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the 5KP170AHE3_A/C datasheet, 5KP170AHE3_A/C pinout, 5KP170AHE3_A/C application, or 5KP170AHE3_A/C equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, P600 package thermal performance, clamping voltage margin versus protected device VDS(max)/VCC, and 175 °C junction temperature capability under repetitive surge conditions.
Technical Context
This TVS diode employs a glass-passivated P600 chip junction optimized for fast response (<1 ns) and low incremental surge resistance, enabling effective suppression of lightning-induced transients and inductive switching spikes. Its unidirectional configuration provides forward conduction path during overvoltage events while maintaining low leakage (<2.0 μA at 170 V) in normal operation.
The device is rated for 500 A non-repetitive forward surge current (8.3 ms half-sine) and derates linearly above 25 °C ambient, with 8.0 W power dissipation on infinite heatsink at TL = 75 °C. It meets JESD 22-B106 solderability (275 °C, 10 s) and JESD 201 class 2 whisker resistance (HE3 suffix).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 170 V - Maximum continuous reverse voltage before clamping begins; defines operating rail margin for 24/48 V systems with safety headroom. |
| VBR (Breakdown Voltage) | 189–209 V at 5 mA - Tight tolerance ensures predictable turn-on threshold across production lots; critical for coordinated protection with downstream fuses. |
| VC (Clamping Voltage) | 275 V at IPPM = 18.2 A - Peak voltage seen by protected circuit during 10/1000 μs surge; must be below absolute max rating of downstream MOSFET or IC. |
| PPPM (Peak Pulse Power) | 5000 W - Sustains single high-energy surges per IEC 61000-4-5 Level 4 (4 kV line-to-line); enables replacement of crowbar circuits without latch-up. |
| TJ(max) | 175 °C - Enables reliable operation in under-hood automotive environments and enclosed industrial enclosures without forced cooling. |
| Polarity | Unidirectional - Provides DC-blocking reverse protection only; requires correct cathode orientation toward positive rail for power-line applications. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD; supports PPAP documentation for Tier 1 suppliers. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; UL 94 V-0 rated; 9.5 mm body length; 1.32 mm lead diameter; color band denotes cathode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path during surge | Connected to system ground or low-side return; carries full surge current to earth reference during clamping event. |
| Cathode | Protected circuit connection point | Connected to positive rail or signal line being protected; clamps voltage to VC when transient exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power (10/1000 μs) | Enables single-event suppression of 4 kV/2 Ω IEC 61000-4-5 surges without degradation; eliminates need for redundant protection stages. |
| AEC-Q101 qualification | Validates robustness across automotive temperature (-55 °C to +175 °C), humidity, and vibration profiles; supports ASIL-B system integration. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage stress on protected devices; improves margin versus MOSFET VDS(max) or IC VCC absolute maximum ratings. |
| P600 thermal mass & solderability | Supports 275 °C/10 s wave soldering and delivers >8 W dissipation on PCB copper pour; reduces thermal runaway risk during repeated transients. |
| Unidirectional polarity only | Simplifies layout and avoids AC-coupled protection complexity; ideal for DC power bus and unidirectional signal line protection. |

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 SMAJ170A | Same VWM (170 V), lower PPPM (400 W), SMA package (lower thermal mass, no AEC-Q101) | Not suitable for automotive or high-reliability industrial use; limited to low-energy signal line protection | Select only for cost-sensitive consumer electronics where 5000 W surge immunity is not required. |
| ON Semiconductor 1.5KE170A | Same VWM (170 V), same P600 package, but 1500 W PPPM and no AEC-Q101 qualification | Lacks automotive qualification and fails IEC 61000-4-5 Level 4; higher clamping voltage (290 V) | Acceptable for legacy industrial designs where AEC-Q101 is not mandated and surge levels are ≤2 kV. |

FAQ
What is the clamping voltage of the 5KP170AHE3_A/C at its rated peak pulse current?
The 5KP170AHE3_A/C has a maximum clamping voltage (VC) of 275 V when subjected to its rated peak pulse current (IPPM) of 18.2 A with a 10/1000 μs waveform. This value is measured per JEDEC standards and guarantees that protected downstream components see no more than 275 V during such a surge event - a critical parameter for ensuring compatibility with 300 V-rated MOSFETs or 280 V-rated capacitors in the same design. The 5KP170AHE3_A/C maintains this clamping performance across its full operating temperature range.
Is the 5KP170AHE3_A/C suitable for automotive applications?
Yes, the 5KP170AHE3_A/C is AEC-Q101 qualified, meaning it has passed rigorous stress tests including temperature cycling, highly accelerated life testing (HALT), and ESD validation required for automotive electronic control units. Its 175 °C maximum junction temperature, unidirectional polarity, and P600 package thermal robustness make it appropriate for under-hood and powertrain applications. The 5KP170AHE3_A/C is explicitly listed in Vishay's AEC-Q101 qualified product matrix for transient suppression in 12 V and 24 V vehicle systems.
What does the "HE3_A/C" suffix mean in 5KP170AHE3_A/C?
The "HE3" suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 class 2 whisker resistance. The "_A/C" denotes the preferred packaging code: "C" stands for 13-inch paper tape and reel, with 800 units per reel. This packaging format is optimized for automated SMT placement and ensures moisture sensitivity level (MSL) compliance per J-STD-020. The 5KP170AHE3_A/C is supplied in this configuration directly from Vishay's certified manufacturing line.
How does the 5KP170AHE3_A/C compare to standard MOV-based protection?
Unlike metal oxide varistors (MOVs), the 5KP170AHE3_A/C offers faster response time (<1 ns vs. ~25 ns), tighter voltage tolerance (±5.5% VBR vs. ±10–20% for MOVs), and no degradation after repeated surges. MOVs exhibit wear-out and increased leakage over time; the 5KP170AHE3_A/C maintains stable parameters across its lifetime. The 5KP170AHE3_A/C also provides precise unidirectional clamping ideal for DC systems, whereas MOVs are inherently bidirectional and require additional polarity management.
Can the 5KP170AHE3_A/C be used in parallel for higher surge current handling?
No - the 5KP170AHE3_A/C is not recommended for parallel operation due to mismatch in dynamic impedance and VBR tolerance, which causes uneven current sharing and potential thermal runaway. For higher surge capability, select a higher-rated part (e.g., 5KP188A) or implement staged protection with upstream MOVs and downstream 5KP170AHE3_A/C clamping. Vishay's application notes explicitly caution against paralleling P600 TVS diodes without active balancing, and the 5KP170AHE3_A/C datasheet provides no derating guidance for such configurations.
