Product details
Overview
TPSMC16AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping inductive switching surges and lightning-induced transients on power and signal lines. It features 16.0 V nominal breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 66.7 A peak pulse current (IPPM), and 22.5 V maximum clamping voltage (VC) - deployed in automotive power rail protection and industrial sensor interface circuits.
For engineers reviewing the TPSMC16AHE3_B/H datasheet, TPSMC16AHE3_B/H pinout, TPSMC16AHE3_B/H application, or TPSMC16AHE3_B/H equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C junction temperature rating, unidirectional polarity, low clamping ratio (VC/VBR = 1.41), and RoHS-compliant matte tin-plated terminals solderable per J-STD-002.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, leveraging passivated anisotropic rectifier technology to achieve fast response (<1 ns) and low incremental surge resistance. Its junction passivation enables stable performance under high-temperature stress (TJ up to 185 °C) and meets MSL Level 1 reflow requirements (260 °C peak).
The device is rated for non-repetitive 10/1000 µs waveform surges only, with derating above 25 °C ambient per Figure 2. Clamping behavior is defined at IPPM = 66.7 A, delivering VC ≤ 22.5 V - critical for protecting 15 V-rated MOSFET gates and microcontroller I/O pins against ISO 7637-2 pulse 1/2a transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 15.2 / 16.0 / 16.8 V - ensures reliable conduction onset above 15 V system operating margin while avoiding false triggering during normal 13.6 V automotive battery transients. |
| VWM | 13.6 V - maximum continuous reverse voltage before leakage exceeds 1 µA; compatible with 12 V nominal automotive and industrial supply rails. |
| IPPM | 66.7 A - peak surge current capability at 10/1000 µs waveform; sufficient to absorb ISO 16750-2 load dump energy without failure. |
| VC | 22.5 V - clamped voltage at IPPM; limits downstream component stress to safe levels below typical 24 V logic and gate driver absolute maximum ratings. |
| PPPM | 1500 W - peak pulse power handling; supports robust protection against high-energy transients in motor drive and power converter applications. |
| TJ max | +185 °C - extended junction temperature rating enables operation in under-hood automotive environments and high-power industrial enclosures. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including HTOL, TC, and HAST testing; required for ECU, ADAS, and body control module designs. |
Pinout & Package
TPSMC16AHE3_B/H uses the SMC (DO-214AB) surface-mount package: 7.11 mm × 6.60 mm × 2.90 mm body with cathode band marking; matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction; connected to protected circuit ground or low-side reference. | Provides return path for surge current; must be routed with low-inductance trace to minimize VL = L·di/dt overshoot during clamping. |
| Cathode | Current exit terminal during reverse-biased clamping; connected to line being protected (e.g., 12 V rail or sensor signal). | Acts as high-impedance input until VWM exceeded; clamps to VC when transient exceeds VBR, diverting energy to ground via Anode. |
Key Features
| Feature | Design Value |
|---|---|
| Passivated anisotropic rectifier technology | Enables stable VBR tolerance (±5%) and <0.1% VBR drift over 1000 hrs at 150 °C - critical for long-life automotive modules. |
| 1500 W peak pulse power (10/1000 µs) | Supports single-event surge suppression in 12 V systems with >100 mJ energy absorption - exceeds ISO 7637-2 Pulse 5a requirements. |
| Low clamping ratio (VC/VBR = 1.41) | Minimizes overvoltage stress on downstream ICs; allows tighter design margins versus competitors with ratios >1.5. |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive use including temperature cycling, humidity bias, and high-temperature operating life - eliminates need for additional qualification testing. |
| MSL Level 1 (260 °C peak) | Enables standard lead-free reflow assembly without pre-baking; reduces manufacturing cost and process complexity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | Lower PPPM (600 W), same VBR (16.0 V), SMB (DO-214AA) package - 30% smaller footprint but 60% lower surge capacity. | Acceptable for consumer electronics with lower-energy transients; insufficient for automotive load dump compliance. | Select SMBJ16A only for space-constrained non-automotive designs where IPPM < 30 A suffices. |
| TPSMC16CAHE3_B/H | Bidirectional variant with identical VBR, VC, and PPPM - adds symmetric clamping for AC-coupled or floating signal lines. | Required for RS-485, CAN FD, or audio lines subject to bipolar transients; unnecessary for DC power rail protection. | Choose TPSMC16CAHE3_B/H when protecting differential or AC signals; retain TPSMC16AHE3_B/H for unidirectional DC rails. |
Compared with SMBJ16A and TPSMC16CAHE3_B/H, the TPSMC16AHE3_B/H delivers optimal balance of 1500 W surge capacity, AEC-Q101 qualification, and unidirectional efficiency for 12 V automotive and industrial power line protection - offering higher reliability than SMBJ16A and lower leakage than bidirectional alternatives in DC applications.

FAQ
What is the breakdown voltage tolerance for TPSMC16AHE3_B/H?
The TPSMC16AHE3_B/H has a breakdown voltage (VBR) range of 15.2 V (min) to 16.8 V (max) at 1 mA test current, corresponding to a ±5% tolerance around the nominal 16.0 V value. This tight tolerance ensures predictable clamping onset across production lots and temperature ranges, supporting consistent protection behavior in automotive and industrial designs where precise voltage thresholds are critical.
Is TPSMC16AHE3_B/H suitable for automotive applications?
Yes, TPSMC16AHE3_B/H is AEC-Q101 qualified and carries the HE3 suffix indicating RoHS compliance and automotive-grade reliability validation. It operates up to +185 °C junction temperature and meets MSL Level 1 reflow standards - making it suitable for engine control units, body electronics, and ADAS modules where sustained high-temperature performance and transient immunity are mandatory.
What is the maximum clamping voltage of TPSMC16AHE3_B/H at rated surge current?
The TPSMC16AHE3_B/H exhibits a maximum clamping voltage (VC) of 22.5 V when subjected to its rated peak pulse current (IPPM) of 66.7 A under the standard 10/1000 µs waveform. This VC value defines the upper voltage limit imposed on protected circuitry during surge events, ensuring compatibility with 24 V-tolerant ICs and MOSFETs commonly used in 12 V systems.
Does TPSMC16AHE3_B/H have bidirectional capability?
No, TPSMC16AHE3_B/H is unidirectional only, as explicitly stated in the Vishay datasheet. It conducts in reverse bias above VBR and blocks forward current up to 3.5 V at 100 A. For bidirectional protection, the pin-compatible TPSMC16CAHE3_B/H variant must be selected - it shares identical VBR, VC, and PPPM ratings but provides symmetrical clamping for AC or floating signal lines.
What package type does TPSMC16AHE3_B/H use and what are its mounting requirements?
TPSMC16AHE3_B/H uses the SMC (DO-214AB) surface-mount package with dimensions 7.11 mm × 6.60 mm × 2.90 mm and a cathode band marking. Mounting requires 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads at each terminal for rated 1500 W pulse power dissipation, per Figure 2 in the datasheet - undersized pads will cause thermal derating and potential failure under surge conditions.
