Product details
Overview
TPC10AHM3/86A from Vishay General Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) in SMPC (TO-277A) package, designed for clamping inductive-switching transients and lightning-induced surges on power rails and signal lines. It features a 10.0 V nominal breakdown voltage (VBR), 8.55 V stand-off voltage (VWM), 14.5 V maximum clamping voltage (VC) at 103 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the TPC10AHM3/86A datasheet, TPC10AHM3/86A pinout, TPC10AHM3/86A application, or TPC10AHM3/86A equivalent, key selection criteria include its 1500 W peak pulse power rating, 185 °C junction temperature capability, low-profile 1.1 mm height, unidirectional polarity, and compatibility with automated SMT placement per J-STD-002 and JESD 22-B102.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve low incremental surge resistance and fast response time under 10/1000 µs transients. Its junction passivation enables stable operation up to TJ = 185 °C, supporting high-reliability automotive and industrial environments where thermal cycling and long-term stability are critical.
The device operates exclusively in unidirectional mode and is not rated for bidirectional surge suppression. Its clamping behavior is defined by VC = 14.5 V at IPPM = 103 A, with a typical VBR temperature coefficient of +0.064 %/°C - enabling predictable voltage shift across operating temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (Nominal) | 10.0 V - precise breakdown threshold at 1.0 mA test current, defining turn-on sensitivity for overvoltage events |
| VWM | 8.55 V - maximum continuous reverse working voltage before leakage exceeds 20 µA, ensuring no false triggering during normal operation |
| VC @ IPPM | 14.5 V at 103 A - clamped voltage during 10/1000 µs surge, limiting downstream IC stress to safe levels |
| PPPM | 1500 W - peak pulse power handling capacity, enabling robust protection against ISO 7637-2 and IEC 61000-4-5 level 4 transients |
| TJ max. | 185 °C - extended junction temperature rating supports under-hood automotive use without derating penalties |
| Polarity | Unidirectional - configured for DC-biased rail protection only; not suitable for AC or bidirectional line protection |
| MSL Level | Level 1 per J-STD-020 - zero moisture sensitivity, allowing unlimited floor life and reflow without baking |
Pinout & Package
Package: SMPC (TO-277A), surface-mount, 3-terminal configuration with cathode band marking. Dimensions: 4.80 × 3.70 × 1.10 mm (L × W × H), compliant with JEDEC TO-277A outline and UL 94 V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Cathode | Connected to protected line; conducts during overvoltage to shunt surge current to ground |
| Terminal 2 | Cathode | Parallel cathode path - dual-cathode structure lowers dynamic impedance and improves clamping consistency |
| Terminal 3 | Anode | Common anode tied to system ground; completes conduction path during transient event |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation | Enables stable VBR and low leakage (<20 µA at VWM) over 15+ year automotive service life |
| Dual-cathode SMPC layout | Reduces effective series inductance and incremental surge resistance for tighter VC control |
| AEC-Q101 qualification | Validated for automotive applications including engine control units, body electronics, and ADAS sensor interfaces |
| 1.1 mm profile | Enables PCB space savings in dense layouts while maintaining thermal mass for 1500 W pulse dissipation |
| Matte tin-plated leads | Ensures reliable solder joint formation per J-STD-002 and passes JESD 22-B102 solderability testing |

FAQ
What is the exact breakdown voltage tolerance for TPC10AHM3/86A?
The TPC10AHM3/86A has a specified breakdown voltage (VBR) range of 9.5 V (min) to 10.5 V (max) at 1.0 mA test current, with a nominal value of 10.0 V. This ±5 % tolerance is measured per ANSI/IEEE C62.35 standards and applies at TA = 25 °C. The device's temperature coefficient of +0.064 %/°C allows accurate VBR prediction across its full -65 °C to +185 °C operating range.
Is TPC10AHM3/86A compatible with lead-free reflow processes?
Yes, TPC10AHM3/86A is fully compatible with standard lead-free reflow profiles, including JEDEC J-STD-020-compliant peak temperatures up to 260 °C. Its matte tin-plated terminals meet J-STD-002B solderability requirements, and the device is rated MSL Level 1 - meaning it has unlimited floor life and requires no pre-baking prior to assembly.
Does TPC10AHM3/86A support bidirectional transient suppression?
No, TPC10AHM3/86A is strictly unidirectional and must be used only on DC-biased lines where reverse polarity is not expected. It lacks symmetrical breakdown characteristics and will not clamp positive transients on grounded lines or negative transients on VCC-referenced nodes. For bidirectional protection, Vishay offers separate devices such as the TPSC10A series.
What is the maximum clamping voltage of TPC10AHM3/86A under standard test conditions?
The maximum clamping voltage (VC) of TPC10AHM3/86A is 14.5 V, measured at a peak pulse current (IPPM) of 103 A using a 10/1000 µs waveform per IEC 61000-4-5. This value is guaranteed across the full operating temperature range and reflects worst-case performance under standardized surge conditions.
How does the dual-cathode configuration in TPC10AHM3/86A improve surge performance?
The dual-cathode structure in TPC10AHM3/86A reduces effective series inductance and distributes surge current across two parallel paths, lowering incremental surge resistance and improving clamping consistency. This results in tighter VC control under high di/dt events and enhanced reliability during repetitive transient exposure - a key advantage over single-cathode TVS diodes like SMAJ10A.
