Product details
Overview
TPC16AHM3_A/H from Vishay General Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) in TO-277A (SMPC) package, designed for high-reliability protection of MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning surges. It features a standoff voltage of 13.6 V, breakdown voltage range of 15.2–16.8 V at 1 mA, clamping voltage of 22.5 V at 66.7 A, and junction temperature rating up to +185 °C.
For engineers reviewing the TPC16AHM3_A/H datasheet, TPC16AHM3_A/H pinout, TPC16AHM3_A/H application, or TPC16AHM3_A/H equivalent, key selection criteria include unidirectional clamping performance, AEC-Q101 qualification for automotive use, low-profile 1.1 mm height, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on consumer, industrial, and automotive PCBs.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of sub-microsecond transients. Its unidirectional architecture provides forward conduction path during overvoltage events while maintaining low leakage (<1 μA at 13.6 V, 25 °C) in normal operation.
The device operates across -65 °C to +185 °C junction temperature range and meets JESD201 Class 2 whisker resistance requirements. Its TO-277A (SMPC) package supports high thermal dissipation and complies with UL 94 V-0 flammability rating, making it suitable for space-constrained, high-reliability board-level protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 µs) | 1500 W - sustains high-energy transients without failure in automotive load-dump or inductive kick scenarios |
| Standoff Voltage (VWM) | 13.6 V - maximum continuous reverse voltage before significant leakage; sets operating margin below breakdown |
| Breakdown Voltage (VBR) | 15.2–16.8 V at 1 mA - precise threshold for initiating clamping; ensures reliable turn-on before downstream damage |
| Clamping Voltage (VC) | 22.5 V at 66.7 A - limits peak voltage seen by protected circuitry during worst-case surge conditions |
| Junction Temperature Range | -65 °C to +185 °C - enables deployment in under-hood automotive, industrial motor drives, and harsh-environment power systems |
| Package | TO-277A (SMPC) - surface-mount, 3-terminal, low-profile (1.1 mm typical height) package compatible with standard reflow profiles |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification |
Pinout & Package
TO-277A (SMPC) is a 3-terminal surface-mount package with cathode-anode-cathode configuration. The package features matte tin-plated leads, conforms to JEDEC TO-277A outline, and measures 4.80 × 3.70 × 1.10 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 (Cathode) | Reverse-biased terminal | Connected to protected line; conducts when transient exceeds VBR, shunting current to ground |
| Terminal 2 (Anode) | Reference/ground connection | Typically tied to system ground; completes clamping path during overvoltage event |
| Terminal 3 (Cathode) | Reverse-biased terminal | Electrically identical to Terminal 1; enables dual-cathode layout for symmetric PCB routing and thermal symmetry |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation | Optimized anisotropic rectifier design reduces leakage drift and improves long-term stability under thermal stress |
| Low profile height | 1.1 mm typical - enables use in ultra-thin modules and stacked-board assemblies where Z-height is constrained |
| MSL Level 1 rating | No floor life limitation - can be stored indefinitely at ≤30 °C/60 % RH without baking prior to reflow |
| Automated placement compatibility | Standard tape-and-reel packaging (1500 pcs per 7″ reel) with precise dimensional control for high-yield pick-and-place |
| Halogen-free & RoHS-compliant | HM3 suffix denotes compliance with environmental regulations and material categorization per Vishay Doc. 99912 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A | Lower PPPM (400 W), higher VWM (12.8 V), SMA package (larger footprint, 2.3 mm height) | Not AEC-Q101 qualified; limited to commercial-grade consumer/industrial use | Select when cost sensitivity outweighs automotive qualification and surge robustness requirements |
| TPC16AHE3_A/H | Same electrical specs but HM3 vs HE3 suffix: HE3 indicates halogen-free + lead-free (Pb-free) plating; HM3 adds JESD201 Class 2 whisker resistance | Identical protection performance; HE3 variant used where whisker resistance is not mandated | Choose TPC16AHM3_A/H for automotive under-hood applications requiring whisker-resistant terminations per JESD201 |
Compared with SMAJ15A and TPC16AHE3_A/H, the TPC16AHM3_A/H delivers superior surge robustness (1500 W vs. 400 W), automotive qualification (AEC-Q101), and mechanical reliability (JESD201 Class 2 whisker resistance), making it the preferred choice for mission-critical automotive and industrial protection where long-term solder joint integrity and high-energy transient immunity are mandatory.

FAQ
What is the clamping voltage of TPC16AHM3_A/H at its rated peak pulse current?
The TPC16AHM3_A/H has a maximum clamping voltage (VC) of 22.5 V at 66.7 A peak pulse current (IPPM), measured using a 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is critical for ensuring downstream components remain within their absolute maximum ratings. The TPC16AHM3_A/H maintains this clamping performance across its full operating temperature range.
Is TPC16AHM3_A/H qualified for automotive applications?
Yes, the TPC16AHM3_A/H is AEC-Q101 qualified, having passed rigorous stress tests including temperature cycling, highly accelerated life testing (HALT), and electrostatic discharge (ESD) per the AEC-Q101 standard. This qualification confirms its suitability for automotive powertrain, body electronics, and ADAS subsystems where reliability under thermal, mechanical, and electrical stress is mandatory. The TPC16AHM3_A/H also supports junction temperatures up to +185 °C, exceeding typical automotive under-hood requirements.
What does the 'HM3' suffix in TPC16AHM3_A/H signify?
The 'HM3' suffix in TPC16AHM3_A/H indicates halogen-free, RoHS-compliant construction with matte tin-plated leads that meet JESD201 Class 2 whisker resistance requirements. It also denotes compliance with Vishay's material categorization standard (Doc. 99912). The 'A/H' denotes revision A in the H-packaging variant - 7″ tape-and-reel with 1500 units per reel. This suffix differentiates it from non-whisker-resistant variants like TPC16AHE3_A/H.
How does the TO-277A (SMPC) package of TPC16AHM3_A/H compare to SMA or SMC packages?
The TO-277A (SMPC) package of TPC16AHM3_A/H offers a 1.1 mm typical height - significantly lower than SMA (2.3 mm) and SMC (2.6 mm) - enabling use in ultra-low-profile designs. It features a 3-terminal cathode-anode-cathode layout for improved thermal symmetry and current sharing, whereas SMA/SMC are 2-terminal. The SMPC also provides higher power density (1500 W vs. 400 W for SMAJ15A in SMA) and better thermal resistance due to optimized copper slug construction.
Can TPC16AHM3_A/H replace TPC16AHE3_A/H in existing designs?
Yes, the TPC16AHM3_A/H is a direct replacement for TPC16AHE3_A/H in terms of electrical specifications, footprint, and soldering profile. The only difference is enhanced whisker resistance (JESD201 Class 2) in the HM3 variant, which adds no design constraints. No PCB layout changes, firmware updates, or requalification are required when upgrading from HE3 to HM3 - the TPC16AHM3_A/H maintains full functional and mechanical compatibility while improving long-term interconnect reliability.
